White spots from the sun

One of the causes of the appearance of white spots on the face and the rest of the body is the lack of response of the skin to sun exposure accumulated throughout life. Melanocytes, the cells responsible for manufacturing melanin, degenerate over time and lose the ability to manufacture melaninand, therefore, to pigment uniformly.These spots white with an oval shape and presence on the neckline, arms or legs, they usually appear with age and are dominated idiopathic guttate hypomelanosis.

White spots due to allergies

In many cases white spots are caused by an allergic reaction. They tend to produce redness and itching that lead to consequent white spots as a reminder on the skin. In these cases it will be convenient to hydrate the skin with soothing and regenerating products that hide the marks

White fungal spots

Another possible cause of white spots on the skin can be fungal infection. It is a very common cause of spots, especially in the summer months, since heat and humidity are essential factors in their appearance. The affected area becomes lighter in this case (although there are also those that become hyperpigmented). They are white spots that grow rapidly if they are not treated and are usually favored, in addition to heat, by pregnancy, oily skin or sweat.

Other causes that can cause white spots on the skin are pigmentation (the person does not produce enough pigment), dermatitis, psoriasis, acne or vitiligo in the most extreme cases.

White spots due to dermatitis

Another cause that favors the appearance of white spots on the skin of the body is atopic dermatitis or eczema, which is more common at an early age. Sometimes, spots appear in the area where the reddish and itchy rash originates, causing dryness. In this sense we talk about pityriasis alba, a type of atopic eczema of unknown origin caused by abundant skin dryness. It produces peeling and a bacterial superinfection whose main symptom is the appearance of white spots.

Other causes

As we have seen, white spots on the skin are not always caused by the sun. There are several dermatological conditions that can also cause its appearance. In summary, we highlight the most common:

  • Vitiligo: An autoimmune condition that causes loss of skin pigment in localized areas.
  • Pityriasis alba: Commonly occurs in children and adolescents, causing pale spots that do not respond to tanning.
  • Skin Fungus: Infections such as tinea versicolor, caused by fungi, lighten the skin tone in specific areas.

Knowing the exact cause of white spots is essential to choosing the appropriate treatment.

Treatment for white spots

It is best to go to a dermatologist to determine the cause of the white spots so that he or she can recommend the appropriate treatment in each case. However, at home there are products that can help improve white spots on the skin:

  • Caused by allergies: it will be important to use regenerating and soothing products to hydrate the skin and reduce the sensation of itching or stinging. Products with aloe vera, panthenol, oat extract or calendula will help the skin achieve these goals. In addition, it will be very important to protect the skin from sun exposure by avoiding staying in open spaces and in the sun unless we wear sun protection and clothing such as hats, caps and t-shirts or long pants.

In addition, it will be advisable to include antioxidants in your routine both topically (you can use the antioxidant creams that we offer) and orally, with ingredients such as vitamin C (also highly recommended for summer), turmeric or phenylalanine that They enhance melanin synthesis and help unify skin tone. 
  • Caused by lack of nutrients: there are also cases in which these white spots appear due to a lack of calcium or vitamins D and E. In this case, it is advisable to change the diet to add an extra supply of nutrients and vitamins.

Atopic dermatitis

Atopic dermatitis is a chronic condition that causes inflammation and can cause light spots on the skin after sun exposure. It is common in people with sensitive skin and usually improves with the use of moisturizing products and sunscreen.

Acroleucoderma puntacta

This type of hypopigmentation, also known as acroleucoderma puntacta, is less common, but can appear in people who are exposed to the sun a lot without adequate protection. Affected areas often have white spots on the skin.

Fungus on the skin

Fungal infections, such as tinea versicolor, are another common cause of white spots. These fungi proliferate in humid and hot conditions, affecting the production of melanin in the skin.

How to remove white spots on the skin caused by the sun?

Removing white spots on the skin caused by the sun requires patience and perseverance. Here are some effective tips:

  1. Gentle exfoliation: Helps eliminate dead cells and improve cell renewal.
  2. Depigmentation creams: Although white spots are not due to hyperpigmentation, these creams help even out skin tone.
  3. Dermatological treatments: Such as light therapy or chemical peels that can improve the appearance of the skin.
  4. Regular dermatological consultations: If the spots do not improve, it is essential to consult a dermatologist.

After a tan, some people may notice small white spots. To treat them, it is recommended:

  1. Moisturize the skin deeply: This helps restore the melanin balance.
  2. Avoid using abrasive products: Opt for mild creams and exfoliants.
  3. Apply sunscreen: Even if the tan has disappeared, it is essential to protect the skin from the sun.

What can I do to prevent white spots from appearing when tanning from the sun?

To avoid the appearance of white spots during tanning:

  1. Apply broad-spectrum sunscreen: Use SPF 30 or higher and reapply every 2 hours.
  2. Avoid prolonged exposure to the sun: Especially between 10 a.m. and 5 p.m. and 4 p.m.
  3. Keep skin hydrated: Well-hydrated skin has greater resistance to sun damage.
