There are several causes that can lead to a rash on your face, from skin conditions like dermatitis to an allergy or an acne breakout. Let’s see each of them:
Dermatitis
It is commonly known as atopic dermatitis and causes inflammation of the skin. Dermatitis is itself the irritation of the dermis or its inflammation and can occur from various causes, such as an allergic reaction. When it comes to the neck and face area it is usually a contact dermatitis, that is, there is some agent that, having been in contact with the skin, has caused the rash. They are usually products such as soaps, detergents or perfumes, although sometimes they are also produced by some jewelery. People who suffer from dermatitis often have very sensitive skin and need to use hypoallergenic products or even medicated creams for their treatment.
Psoriasis
Psoriasis is a skin condition due, in this case, to a immune system condition. It produces a rash on the face, especially in the area of the temples, which can lead to dryness and loss of dry skin. In this case, the immune system stimulates the production of skin cells and that is why the rash occurs. You have to be careful when leaving wounds, as they could become infected. Psoriaris can be treated with specific creams or soaps.
Seborrhea
In seborrheic dermatitis, the secretion of the sebaceous glands of the skin increases. Seborrhea is similar to psoriasis but it also produces scales. Also, the flakes are usually yellowish in color rather than white.
Irritation
Another reason why a rash can appear on the face is irritation. In men it is very common after shaving. It is because the cut hairs are pushed into the follicle, causing irritation. For this reason, it is advisable to apply a good moisturizer after shaving and do it with a damp face and accompanied by a specific gel that softens the hair and opens the pores. Or just after the bath, where the hot water has acted to open the pores. The razor or blade must be suitable and sharp and the cut must be made in the direction of hair growth and not the other way around, as is thought.
Allergy
Allergy is the main cause of rash on the face. It usually appears due to skin contact with the product that causes the reaction, although it can also appear due to some foods. To avoid this, you should eliminate from the diet those foods or drinks to which you are sensitive, or avoid those products (soaps, creams …) or utensils and materials that cause the reaction. However, once it has appeared, it can be treated with antihistamines. Depending on the reaction, these will be taken orally or even injected. Sometimes they require several injections throughout the year.
Acne
There are many types of acne. They usually affect mainly adolescents, but it can also appear in adults. Although it is thought that it only affects people with oily skin, the truth is that this condition can appear in any type of skin, although it is true that in these it is more common. Some types of acne can cause rashes.
Heat rash
When a person is too hot and sweats, the sweat glands become clogged if the sweat is excessive, causing possible breakouts or rashes. The acids in sweat in contact with the skin also play a role.
Lupus erythematosus
It is an autoimmune disease that affects many organs in the body. In the case of the face, a reddish rash usually appears, like a kind of spot, very characteristic for its shape like a butterfly. It is a disease that can be treated but has to be done from within, as it affects the immune system. However, it is recommended to avoid exposure to the sun when suffering.
Infections
However, the rash does not only appear due to the reasons mentioned above, but it can also be due to infections. This is the case of eruptive diseases such as chickenpox or measles. In this case, in addition to blisters, they can cause rashes all over the body, also affecting the face. Also, it can be due to folliculitis where the hair follicle becomes infected.
Treatment of the rash on the face will depend at all times on the cause that caused it. The best is go to the doctor as soon as possible so that it can make a diagnosis and offer you the best treatment. If the rash is not treated, it may increase or even reappear.
In some cases, such as allergy, they are usually used antihistamines or simply trying to avoid the substance that causes the condition. Antihistamines, as well as corticosteroids (sometimes also prescribed in these cases), will help reduce itching, inflammation, and pain.
When it comes to an immune problem, they are usually treated with immunomodulators to decrease or increase the function of defenses, depending on the disorder suffered.
