Skin redness: causes
There are several factors that can cause skin redness. Among the most common are:
Inflammatory conditions, such as eczema and rosacea, can cause redness, itching, and skin irritation;
Allergic reactions to certain substances, usually found in skincare products, perfumes, makeup, and cleaning products, manifest as skin redness;
Prolonged sun exposure can cause skin redness, sunburn, and even skin cancer;
Exposure to heat can cause skin redness, especially on the face;
Viral and bacterial infections are also among the causes of erythema.
Below, we present some skin problems that have skin redness as a symptom:
Sunburn
Sunburn is a common skin problem that occurs when overexposed to the sun's ultraviolet (UV) rays. Symptoms can appear even after just a few minutes of exposure. Redness and painful irritation are the main effects of overexposure to the sun, especially without adequate protection.
In some cases, prolonged sun exposure can cause more serious health problems, such as heatstroke or skin cancer.
Rosacea
Rosacea is a chronic condition that affects millions of people worldwide. It usually manifests as redness and visible blood vessels on the face, especially on the cheeks, nose, chin, and forehead. Rosacea usually develops after the age of 30. Initially, the redness appears and disappears. However, once it becomes more intense and persistent, dilated blood vessels may also be observed.
? Try Ivatherm products, recommended by dermatologists, for treating rosacea:
Rosederm Cream for sensitive skin with couperose – reduces redness, irritation, the number and size of visible small veins of sensitive skin with rosacea, improves peripheral microcirculation, preventing the appearance of other visible capillaries, has a repairing and anti-inflammatory action.
Rosederm Cream for sensitive skin with couperose SPF30 – has a repairing, calming, anti-irritant action on very fragile skin and prevents the increase of intradermal temperature. UVA and UVB sun filters protect the skin from the harmful effects of solar radiation.
Rosederm Micellar Anti-redness Lotion – gently cleanses, removes makeup and calms fragile and irritated, slightly reactive skin, rebalancing the pH. It is recommended for daily care of couperose skin and seborrheic skin, with redness and flakes.
Eczema
Eczema is also known as atopic dermatitis. It is one of the most common skin conditions, which can affect babies, children and adolescents, as well as adults and the elderly. Generally, eczema begins in childhood, but symptoms can reappear in adulthood.
One of thesymptoms of atopic dermatitis is skin redness, accompanied by itching, dry and scaly patches, edema (swollen, puffy skin) and, in some cases, bleeding may occur.
Eczema looks different depending on a person's skin tone. Eczema usually appears as red patches accompanied by scaling and itching.
? Test: Ivahidra + Intensive Relipidant Balm – reduces the intensity and frequency of flares in atopic dermatitis, due to its complex mechanism of action: restores the skin's barrier function and microbiome, intensely and durably hydrates, reduces redness and irritation associated with severely dry skin, reduces the sensation of itching.
One of the most common types of eczema is contact dermatitis. This form of dermatitis occurs when the body reacts to an irritant or a harmful substance. Allergic contact dermatitis is an immune system reaction to an irritant (latex or metal) and irritant contact dermatitis occurs when a substance, usually in repeated contact, irritates the skin.
Factors that trigger contact dermatitis include soaps, detergents, solvents, jewelry, latex, and poisonous plants.
? Try: Cicaderm Barrier Cream – isolates, repairs, and protects skin exposed to external aggressions and prevents the appearance of contact dermatitis. It restores skin integrity, soothes the skin, and provides a long-lasting state of comfort.
Autoimmune diseases
There are several types of autoimmune skin diseases, which occur when the immune system attacks healthy skin cells and causes, among other things, skin redness.
Psoriasis is one of the most well-known skin conditions. The exact cause of psoriasis is still unknown, but scientists believe it is a combination of genetic and environmental factors. People with a family history of psoriasis are more likely to develop this condition, as are those with a weakened immune system.
Usually, the body takes several weeks to produce new skin cells to replace dead ones. Psoriasis occurs when the immune system mistakenly attacks healthy skin cells, causing them to grow and reproduce faster than normal. This can lead to the appearance of red, dry, and scaly patches.
The rash most commonly forms on the elbows, knees, lower back, scalp, and genitals.
Another chronic condition that can cause facial redness is cutaneous lupus. It is an autoimmune skin condition in which the immune system attacks healthy cells and damages the skin. Symptoms include redness, itching, pain, and scarring. Some people with lupus develop a butterfly-shaped rash on their forehead.
Viral diseases
Skin rashes are a common symptom of many viral diseases, such as chickenpox, measles, and shingles.
The appearance of viral rashes can vary. They can appear as red, brown, or purple spots and can develop only on one part of the body or spread.
Measles is an infection caused by the measles virus and causes a spotty rash all over the body.
Chickenpox is an infection caused by the varicella-zoster virus and initially manifests as red spots. Subsequently, edema and vesicles appear.
The varicella-zoster virus remains dormant in the body and can cause, in adulthood, Shingles, which manifests as a red, very painful rash that can cause tingling, itching, or burning.
Another viral condition that manifests as skin redness is erythema infectiosum, also known as fifth disease or slapped cheek syndrome. The infection is caused by parvovirus B19 and manifests on the cheeks, which become red and shiny.
West Nile and Zika virus infections, transmitted by mosquito bites, also cause rashes on the face, trunk, arms, or legs.
Most of these viruses are highly contagious. Some of them can be prevented by vaccination, while for others there is no specific treatment.
? Use: Herculane Thermal Water spray to soothe and protect sensitive skin. Ivatherm product is beneficial for all skin types, with proven properties for all degrees of skin sensitivity, from sensitive to intolerant or allergic.
Folliculitis
Folliculitis is the name for an infection of a hair follicle on the skin. When it is infected, the skin around it can become red. Slight bumps may also appear.
Folliculitis occurs when bacteria or fungi enter the hair follicle. Shaving, as well as epilation, can cause folliculitis.
Skin redness: prevention
There are several simple methods to prevent skin redness:
Avoiding known triggers, such as allergens and irritants;
Using gentle, fragrance-free and hypoallergenic cosmetic products;
Washing hands after contact with a known allergen or irritant;
Avoiding prolonged sun exposure, especially during peak hours (10:00 AM – 4:00 PM), when ultraviolet rays are stronger, and applying a cream with sun protection factor every day;
Avoiding crowded places, where viruses are more easily transmitted, as well as people suffering from certain viral diseases;
Constantly hydrating the skin, both by applying cosmetic products appropriate for the skin type and by consuming at least two liters of liquids every day;
Avoiding hot water, which can cause irritation by removing the skin's natural oils;
Managing stress levels, an aggravating factor for certain inflammatory skin conditions, such as eczema and psoriasis.
Skin redness: treatment
Before undergoing treatment, it is important for a specialist doctor to determine the cause of skin redness. Based on the patient's medical history, as well as family history, analyzing symptoms and possible exposure to irritants or allergens, a dermatologist can make a correct diagnosis. In some situations, allergy tests, blood tests, or a skin biopsy are needed, as there are numerous factors that can cause a rash, which is why diagnosis can be difficult to establish.
Among the most common treatments for red skin are:
Removing irritating products from the skin care routine;
Using gentle cleansing products and moisturizing creams that contain soothing ingredients that can reduce inflammation and rebuild the skin's protective barrier;
Applying cold compresses to the skin to calm redness and reduce inflammation.
Lifestyle changes (avoiding triggers, managing stress, and maintaining a healthy diet) can help prevent skin redness and improve overall skin health.
In conclusion, redness is a symptom of many skin conditions and problems. Redness can be caused by numerous factors and can be unsightly, as well as bothersome. Even when redness comes from a condition for which there is no cure, symptoms can be managed through a few accessible measures. Sun protection, avoiding allergens, and keeping the skin hydrated can help prevent skin redness.
