Redness on the face can happen due to prolonged exposure to the sun, during moments of anxiety, shame and nervousness or when you are doing physical activity, being considered normal.
However, redness on the face can arise due to some he alth conditions, and may be indicative of autoimmune diseases, such as systemic lupus erythematosus, or indicate allergies.
As redness on the face can be indicative of several situations, the most appropriate thing to do is to seek advice from a dermatologist when the cause of the redness cannot be identified or when other symptoms arise, such as joint pain, fever, swelling of the face or increased sensitivity of the skin, for example.
The main causes of redness on the face are:
1. Heat and sun exposure
Staying in the sun for a long time or in a very hot environment can make the face a little redder, which is considered normal. This is due to the dilation of blood vessels in the skin.
However, in cases of prolonged exposure to the sun, skin redness may be related to sunburn, which causes skin cell damage and inflammation, leaving the face red.
What to do: It's important to wear sunscreen daily, not just when you're going to spend a lot of time in the sun. That's because in addition to protecting the skin against the sun's rays, the protector prevents the appearance of stains and slows down the aging of the skin. In addition, it is recommended to wear lighter clothes, to relieve the discomfort caused by excessive heat, and to drink plenty of fluids during the day, as this is also possible to avoid dehydration.
2. Psychological situations
It is common for the face to redden when the person is in more stressful situations, which generate anxiety, shame or nervousness, because in these situations there is a rush of adrenaline, which makes the heart accelerate and body temperature begins to rise, in addition to dilating blood vessels, increasing blood flow. As the skin on the face is thinner, this increase in blood flow can be easily noticed through the redness on the face.
What to do: as redness only reflects a psychological state at the moment, it is best to try to relax and get comfortable with the situation. As time passes, the changes caused by the adrenaline rush, including redness in the face, diminish. If these changes are frequent and interfere with personal or professional life, it is important to seek help from a psychologist, so that relaxation techniques can be adopted, for example.Check out some relaxation techniques.
3. Intense physical activity
Redness on the face due to physical activity is common, as in these cases there is an increase in heart rate and, consequently, increased blood flow, which makes the face redder.
What to do: as the red face is just a consequence of physical activity, it is not necessary to take any specific measures for this, because as the person relaxes, the momentary changes caused by the exercise disappear, including the redness of the face.
4. Systemic lupus erythematosus
Systemic lupus erythematosus, or SLE, is an autoimmune disease characterized primarily by the appearance of a red butterfly-shaped patch on the face.
In this disease, the immune system cells attack the body's own he althy cells, as if they were foreign to the body, causing joint inflammation, tiredness, fever and the appearance of sores inside the mouth or nose, for example..Know how to recognize the symptoms of lupus.
What to do: the treatment indicated by the doctor should be carried out according to the symptoms and severity of the disease, and the use of anti-inflammatory drugs may be recommended, corticosteroids or immunosuppressants, for example. See how systemic lupus erythematosus is treated.
Furthermore, lupus is characterized by periods of crisis and remission, that is, periods in which symptoms are not observed and periods in which signs and symptoms are quite present, which justifies the treatment to be carried out in a uninterrupted way and the medical follow-up happens regularly.
Redness on the face can also be a sign of allergy, and is usually related to food or contact allergies. Allergy is also related to the fact that the person's skin is more sensitive, which can result in redness when the person passes a different cream on their face or washes it with a soap they are not used to, for example.
What to do: In these cases, it is important to identify the triggering factor and avoid contact or consumption. In addition, it is important to consult a dermatologist so that a skin assessment can be carried out and specific creams or soaps for the skin type can be recommended, avoiding allergic and hypersensitivity reactions.

Rosacea is a skin disease of unknown cause, which is characterized by redness on the face, especially on the cheeks, forehead and nose. This redness arises as a consequence of exposure to the sun, excessive heat, use of some dermatological products, such as acids, consumption of spicy foods, alcohol abuse and psychological factors, such as anxiety and nervousness.
In addition to redness on the face, in some cases it is also possible to observe increased skin sensitivity, feeling of heat on the skin of the face, swelling in the face, appearance of skin lesions that may contain pus and drier skin.
What to do: Rosacea treatment should be indicated by a dermatologist and aims to relieve symptoms and improve the person's quality of life. Thus, it may be recommended to apply a cream on the area of redness or just neutral moisturizing soap, in addition to sunscreen with a high protection factor. Understand how to treat rosacea.
7. Slap disease
Slap disease, scientifically called erythema infectiosum, is an infectious disease caused by Parvovirus B19 characterized by impairment of the airways and lungs, mainly in children.
In addition to the flu-like respiratory symptoms, such as fever and runny nose, it is possible to verify the appearance of red spots on the child's face, as if he had been slapped in the face, and also on arms, legs and trunk, associated the slight itch. The presence of a red spot on the face is one of the main factors that make it possible to differentiate erythema infectiosum from the flu.
What to do: It is important that the child is taken to the pediatrician so that the diagnosis can be made and the treatment can be started, the most appropriate one that can be done through the rest and drinking plenty of fluids, as the immune system can easily eliminate the virus from the body. Your doctor may also recommend medication to relieve symptoms, such as antipyretics or anti-inflammatories, such as acetaminophen or ibuprofen, for pain and fever, and antihistamines, such as loratadine, for itching.
Although the immune system is able to resolve the infection, it is important that the child is followed up by a pediatrician to check if there is a risk of complications, such as severe anemia, in children with a weakened immune system or who have a known blood disorder, since the disease is easily transmitted to other people, often affecting several members of the same family.
Telangiectasia, also known as vascular spiders, is a common skin disorder that causes small red spider veins to appear on the face, especially in more visible regions such as the nose, lips or cheeks, causing redness on the face., which may be accompanied by a slight sensation of itching or pain.
What to do: you should consult the dermatologist who can indicate the most appropriate treatment that can be done with laser application directly on the spider veins, which increases the local temperature and closes them, making them less visible, sclerotherapy in which a substance is injected inside the spider veins to make them thinner, and in some cases, surgery.

9. Cold exposure
Redness on the face can also be caused by exposure to cold, such as in the winter period or even due to the profession, such as working in environments with low temperatures, such as a refrigerator, for example.
This is because low temperatures or cold and dry wind can reduce the oiliness of the skin, causing damage to the epidermis, which is the outermost layer of the skin, responsible for the skin's natural protective barrier.
In this way, the skin of the face, especially the cheeks and nose, can become irritated and inflamed, resulting in redness, increased sensitivity, or peeling.
What to do: Face moisturizers should be used, especially those containing ceramide or hyaluronic acid, as they retain water in the skin and increase the protective barrier. In addition, you should avoid very hot baths, as they increase the dryness of the skin, and you can use a humidifier at home, in order to increase the humidity of the air, which helps to avoid excessive drying of the skin. In more severe cases, the doctor may recommend the use of corticosteroid ointments.
