    Pictures of Skin Infections

    Medically Reviewed by Carol DerSarkissian, MD on February 22, 2023

    Like an onion, your skin has layers. When it comes to infections, usually the deeper it is, the worse it can be. The first layer (epidermis) makes cells and gives you color. The second (dermis) makes oils to protect the skin and sweat to cool you. Its nerve endings help you feel heat, cold, and pain. The third layer (subcutaneous fat) attaches skin to muscles and bones, and helps control your temperature.

    A cut in your skin — from an injury or surgery, for example — makes it easier for germs to get in, and that can lead to infection. Viruses, bacteria, and fungi can all cause them. Bacteria are living organisms that are all around you. Many are harmless or even good for you, but some can cause problems. Viruses are tiny particles that can only grow inside other living cells. Fungi are living organisms that feed off other living things.

    Ones caused by bacteria usually can be cured with antibiotics, though some bacteria have become resistant to the drugs and are harder to kill. Medication or prescription creams can stop most fungal infections, and there are several ways to treat viruses. Your doctor may recommend antiviral medicines, or they might need to remove skin growths. In other cases, your symptoms may go away on their own.

    Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection that antibiotics don’t always stop. It can cause an abscess — pus in your tissue. If you have one, your doctor may drain it and not give you medicine. People who’ve been in a hospital or other facility, like a nursing home, are most likely to get MRSA. Those who often have skin-to-skin contact with others, like wrestlers or child care workers, can get it, too.

    This is a serious bacterial skin infection that happens most often on your lower leg, but it can be anywhere on your skin. The area may get swollen, hot, and tender. It can be very serious if it’s in deeper tissue and gets in your bloodstream. If you have red streaks on your skin, fever, chills, and aches, see your doctor right away. In serious cases, you’ll need IV antibiotics — a needle in your hand or arm that puts medicine into a vein.

    This is a bacterial infection that’s common in preschool and school-age children. It can cause blisters and sores on the face, neck, hands, or diaper area. It often happens after the skin has been irritated by another problem like a cut, scrape, or rash. It can be cleared up with antibiotics (in ointment, pill, or liquid form).

    Also known as flesh-eating bacteria, this is a life-threatening infection that spreads quickly and kills your body’s soft tissue (muscle, fat, and other tissue that connects muscles to bones). If you’re healthy, have a strong immune system, and bathe or shower often, you’re not likely to get it. If you do have it, you’ll need antibiotics put directly into one of your veins, and a surgeon will remove the infected tissue. 

    This happens when follicles — tiny pouches of skin that hold the roots of your hair — get inflamed and cause red, itchy, burning skin, tenderness, and pain. It’s usually brought on by bacteria, but fungi and viruses can cause it, too. Folliculitis often goes away on its own, but if it doesn’t, your doctor may give you an antibiotic or antifungal cream.

    A boil is a sore that starts as a red, tender bump, gets more painful as it fills with pus, and finally bursts. It happens when bacteria infect one or more hair follicles, often getting in through a cut or insect bite. A carbuncle is a cluster of boils under your skin. A warm washcloth on the area is usually enough to ease pain and help boils drain, but if it’s large, your doctor may make a small cut to let the fluid out.

    This is typically linked to sores in the genital area in both men and women, caused by a form of the herpes virus (type 2). Once you’re infected, the virus stays in your body, but it doesn’t always cause sores. Your doctor can give you medicine to control outbreaks. It’s contagious, so you shouldn’t have sex when you have an outbreak. If you do, tell your partner, and use a condom so you’re less likely to pass it on.

    The type 1 herpes virus causes these on your lips or mouth, and they can be painful and embarrassing. Most people get the virus as children from contact with people who have it. The virus stays in your body, and sores may break out when you’re sick, anxious, or overtired. They usually go away on their own, but prescription drugs can help control outbreaks.

    This virus affects your whole body and is mainly known for its itchy rash. Most of the time, it goes away within a week. It’s very contagious, so if you have it, stay home and rest until it’s gone. Once you’ve had chickenpox, you won’t get it again, but you may have an outbreak of shingles later in life — a painful, itchy rash. Vaccines can make you less likely to get chickenpox and shingles, or make you less sick if you do get one of them.

    This virus causes smooth, firm, mounds of skin with a dimple in the center, and you get it from contact with people who have it or things they’ve touched. The itchy, painful sores can show up almost anywhere on your body — as small as a pinhead or as big as a pencil eraser. They usually disappear in 6 to 12 months, but your doctor may give you a cream or suggest office treatments that freeze or scrape the nodules away.

    This fungal infection causes red, itchy, ring-shaped rashes on the top layer of your skin. It can show up anywhere on your body, and it’s very contagious. Many types of fungi can cause it, and they’re all around you. They can live on your skin as well as on floors, countertops, clothing, towels, and bedsheets. A number of antifungal creams, sprays, and pills can get rid of the infection, but it sometimes comes back in problem areas.

    The same types of fungi that cause ringworm can cause this, too. It often shows up on the bottom of your feet and between your toes, where it’s dark and moist. It can make them itchy, dry, and cracked, and can sometimes cause bleeding. Many locker room floors are covered in it, so use rubber flip-flops at the gym — and clean them often. Keep your feet clean and dry to keep it from coming back.

    Tiny creatures can burrow into your skin and feed or lay eggs, which can cause red, irritated, itchy skin. Lice are common parasites, especially in children. They affect the scalp and pass easily from person to person. Other skin parasites are mites (scabies) and hookworm, called “creeping eruption.” Special creams, lotions, or shampoos can get rid of them, and they don’t often cause long-term problems.

      Skin texture

      Leather – one of the largest organs in the human body. It is elastic, strong enough, differs in texture and thickness in different parts of the body. Consists of two main layers – epidermis and dermis .


      refers to the superficial layer of the skin and consists of several layers of skin cells.


      is located under the epidermis and consists of elastin fibers that provide mobility to the upper integument and protein fibers (collagen) that give the skin strength. The dermis contains sebaceous glands, hair follicles, nerves and blood vessels.

      Injuries to the skin from cutting objects can affect both the epidermis and the dermis.

      Cuts by depth

      Small cuts

      Small cuts go through the upper layers of the skin. With timely treatment of the damaged area of ​​​​the skin, such wounds rarely become infected.

      Damage can be caused by fingernails, a piece of metal, a tree branch or a bush.

      Usually a minor cut or scrape can be treated at home. The main thing is that there is no contamination in the wound surface.

      Deep cuts

      Deep cuts go through all layers of the skin.

      They occur when the skin is exposed to a sharp object: a knife, a razor, a piece of glass or a sharp edge of a piece of metal. On examination, it is important to make sure that there is no contamination in the wound.

      If the size of the damage is significant, then it is necessary to seek medical attention in order to apply stitches.

      Cuts require first aid.

      A deep cut involving an artery is a medical emergency.

      Help for cuts

      First aid for cuts required 2.3 :

      • b bleeding by pressure on the wound
      • Treat the wound with sterile saline or clean water
      • Treat the wound with an antiseptic, such as Betadine solution ®
      • Cover the cleaned wound with a sterile dressing
      • Monitor the cleanliness of the wound

      How to treat cuts, see a short video with surgeon Fedor Yanovich Kraskovsky

      How to determine damage to the vessel

      If the cut is deep and the bleeding does not stop, then the vessel is most likely damaged. In this case, you need to seek professional medical help.

      Bleeding from an artery:

      Blood is bright scarlet and gushing from a wound

      Bleeding from a vein:

      blood is dark red and flows slowly from the wound

      During transport to the hospital, you should: possibly (

    • Do not remove the bandage if it is soaked with blood, but instead put a fresh bandage over it

    Cut healing phases

    There are four phases of cut healing:

    Exudation phase

    Transfer of the liquid part of the blood through the vessel wall to the site of injury

    Resorption phase

    Reverse absorption of fluid from the site of injury

    Proliferation phase

    New growth tissues

    Regeneration phase


    During the first two phases inflammation develops.

    Inflammation occurs in response to damage to the skin and serves as a protective reaction of the body to a cut: it separates the injured area from intact tissues. After delimitation, the body immediately begins to repair the wound, and this process can continue for several days, weeks, months, or even years, it all depends on the injury.

    As the cut heals, the following processes are observed:

    • After the cut occurs, the body begins to turn on protective functions. The blood vessels in the wound constrict, thereby reducing blood loss. A clot forms in the damaged area.
    • After a clot has formed, the blood vessels dilate, providing maximum blood flow to the damaged area. This leads to symptoms of inflammation (pain, swelling). Further, leukocytes (blood cells) rush to the site of the wound and begin to clean the damaged area from bacteria, microorganisms and other foreign agents.
    • At the site of the cut, the process of tissue repair is underway: new collagen fibers are formed and blood vessels are restored. All of this supports the healing process.
    • The wound begins to shrink along the edges, its size decreases.
    • Superficial skin cells migrate from one side of the wound to the other, a new area of ​​skin is formed.
    • Depending on the depth of the cut, it may leave a scar. As a rule, scar tissue is not as durable as intact skin.

    Factors affecting wound healing

    Injured skin heals at different rates depending on the individual characteristics of the body and environmental factors, which include:

    • General state of human health
    • Age – in older people, the skin recovers more slowly than in young people
    • State of the immune system
    • Dietary habits
    • Weather conditions
    • Degree of infection of the wound
    • 90 005 Bad habits (smoking, alcohol, drugs)

    • Concomitant diseases (diabetes, cancer)

    Treatment of cuts

    There is a great variety of preparations for the treatment of cuts, differing both in the main active substance and dosage form 4,5,6 .


    Povidone Iodine

    Betadine ® Solution is manufactured at a concentration of 10%. For the treatment of cuts, the drug can be used without dilution or diluted 1:10 and applied as a 1% solution (2 X 5 ml (2 teaspoons) and 100 ml (½ cup) 10% solution) 2.3 . It should be diluted with saline, Ringer’s solution, phosphate buffer solution, water for injection, in extreme cases, with clean drinking water.

    Povidone-iodine has antiseptic, antiviral, antifungal, antiprotozoal activity.

    Active against Gram-positive and Gram-negative bacteria.

    Unlike 5% iodine in alcohol, povidone-iodine can be applied directly to a cut. It does not cause burning, does not dry the skin, does not interfere with tissue regeneration.

    Chlorhexidine bigluconate

    Chlorhexidine bigluconate is an antiseptic that fights bacteria, fungi and viruses. It exists in the form of an aqueous and alcoholic solution. For the treatment of cuts, a 0.2-0.5% aqueous solution should be used. An alcohol-based drug can cause unpleasant reactions in the form of a burning sensation, as well as slow healing.

    Hydrogen peroxide

    The solution is produced and used at a concentration of 3%. Hydrogen peroxide has a hemostatic effect, helps to remove dirt from the wound mechanically due to the formation of gas bubbles. The use of hydrogen peroxide can cause allergic reactions.



    Betadine ® ointment contains 100 mg of povidone-iodine. The agent acts on gram-positive and gram-negative bacteria, contributes to the destruction of their cell wall. The ointment has a wide spectrum of action, namely: antiseptic, antiviral, antifungal, antiprotozoal 11 . The drug demonstrates anti-inflammatory action, accelerates the healing of wound surfaces, demonstrating a low level of cytotoxicity (damage to tissue cells due to its antimicrobial action) 12 .

    Povidone-iodine in a convenient dosage form in the form of an ointment allows you to carry the drug with you and use it at a convenient time, applying, for example, under occlusive dressings.

    Unlike 5% iodine solution, which contains alcohol, ointment based on povidone-iodine does not dry the skin, does not cause discomfort.

    A clinical study has shown that the combination of 1% solution and 10% Betadine ® ointment has a high clinical effect in the treatment of wounds and cuts 5 .


    Dexpanthenol is a derivative of pantothenic acid, vitamin B5. The drug is able to moisturize the skin, strengthen its barrier function, prevent skin irritation, promote wound healing, and have an anti-inflammatory effect 7 .

    Dexpanthenol stimulates skin regeneration, activates the genes responsible for wound healing.

    Chloramphenicol and dioxomethyltetrahydropyrimidine

    It has a wide spectrum of antimicrobial and anti-inflammatory action, which persists even in the presence of blood, pus. It penetrates into the wound and stimulates its healing, has an anti-inflammatory effect.

    However, the ointment may cause allergic contact dermatitis spreading like nodular pruritus, as well as changes in taste, headache 8 .

    Betadine® Solution and Ointment Cut Flow Chart

    Prepare everything needed to treat the cut 5.6 water)

  • Betadine 10% solution ® or Betadine 1% solution prepared ®
  • Betadine ointment ®
  • Gauze, cut patch
  • 90 016 Wash your hands and wear gloves to prevent infection

    Treat the wound as follows:

    • Clean the injured area with saline or water.
    • Remove loose particles or objects. To do this, twist the gauze to form a “corner” and remove foreign bodies.
    • Treat the wound with 10% or pre-prepared 1% solution of Betadine ® . Dry the wound with gauze or a napkin with blotting movements.
    • Apply a thin layer of Betadine ® Ointment directly to the wound and cover with a sterile gauze dressing, cover with plaster. You can also apply the ointment first to the dressing and then to the wound.
    • Repeat the procedure until the wound heals.

    Frequently asked questions

    What should I do if I cut myself?

    The most important thing is not to panic. Wash the wound with water or saline, treat with an antiseptic, for example, solution Betadine ® . To stimulate healing, you can use ointments. If you cannot stop the bleeding on your own or the wound does not heal for a long time, festering, consult a doctor.

    How to treat the cut?

    Treat the cut with antiseptics. Aqueous solutions of antiseptics, for example, Betadine ® solution, can treat the entire wound field, alcohol – only the edges of the wound. After treatment, it is desirable to apply ointment Betadine ® for faster healing.

    How to stop bleeding from a cut?

    After cleansing the wound, cover the wound with a sterile dressing and apply pressure to the cut, elevating the injury above the level of the heart, if possible (for example, in case of a hand injury). If the blood pulsates, and it is not possible to stop the blood on its own for a long time, then you should seek qualified medical help.

    Infected wounds – diagnosis and treatment at the medical center “Andreev hospitals”

    In case of injury (with insufficient treatment), infection of the wound may occur. This is due to the fact that when injured, microbes enter the wound area, which can subsequently multiply. that the infection does not penetrate when a certain part of the body is affected, but with subsequent improper care of it – microbes can be introduced from clothing or from surrounding objects (in the event that a person walks without a bandage).0021

    As a rule, it is possible to detect this disease a week after the infection has got. Of course, getting an infection into a wound does not always lead to the fact that bacteria begin to multiply. Bacteria begin to develop in the area of ​​injury, usually resulting in sepsis. This is a very serious disease that can occur if the patient has not received timely assistance.

    Causes of infection of wounds

    Usually pathogens that contribute to the development of the strongest infection are various kinds of bacteria or viruses. They can enter the human body if it does not follow the rules of hygiene, which must necessarily be accompanied by the use of antiseptics. It happens that tissue infection occurs during the implantation of prostheses. In this case, the body cannot accept foreign material, and suppuration begins to develop. In people who do not monitor their health and eat improperly, immunity weakens. This causes the wounds to fester. Experts have found that people who have chronic, untreatable diseases, infection occurs much more often than those people who are completely healthy.

    Symptoms of infected wounds

    When a wound becomes infected, the following symptoms are possible:

    • Redness is noted in the place where the infection has occurred.
    • Possible tissue swelling.
    • Many patients note the appearance of severe pain.
    • Since an inflammatory process begins throughout the body, as a result, the patient’s body temperature rises.
    • Purulent discharge at the wound site.
    • Tachycardia.
    • Headache, nausea.

    If any of the above symptoms appear, you should immediately consult a doctor, as the consequences can be extremely serious.

    Diagnosis of infected wounds

    It is not recommended to diagnose the disease on your own, you should seek help from an experienced doctor who works in the field of surgery. First of all, the doctor will collect an anamnesis, after which the patient will be offered to undergo a series of activities, which must include a blood test, as well as x-rays.

    Treatment of infected wounds

    If the disease is complicated, the patient will need surgery. After that, the doctor must prescribe medications to the patient that will act on microbes, in other words, they will kill all harmful microorganisms, and also remove the inflammatory process. As a rule, these are antibiotics. If the patient is not very severe, then the following measures are usually applied:

  • Daily dressings are required and must be done using only sterile bandages.
