The dermatologist explains the main risk factors and strategies for maintaining healthy skin in summer
Summary
Summer and intense sun exposure worsen melasma, causing dark spots and the appearance of new lesions. Prevention is essential with sunscreens, hats and treatments indicated to control melasma.
Summer brings with it longer days and intense sun exposure, which can worsen skin problems like blemishes and melasma. Melasma is a condition characterized by the appearance of dark spots, especially on the face, influenced by hormonal and genetic factors and, mainly, by exposure to ultraviolet (UV) rays.
Why does melasma get worse in summer? Solar radiation is the main factor that triggers and worsens melasma. “UV rays stimulate the production of melanin, the pigment responsible for skin color. In people predisposed to melasma, this causes the darkening of existing spots and the appearance of new lesions,” explains dermatologist Fátima Tubini.
Not only the sun, but also the heat itself can worsen the condition. “Heat stimulates the release of inflammatory mediators in the skin, which also contributes to hyperpigmentation. Therefore, even visible light, such as that emitted by cell phones and computers, can represent a problem,” explains Tubini.
The specialist underlines that prevention is the main ally in the fight against melasma, especially in the summer period.
• Use of sunscreen: “Sunscreen should be applied daily, with a sun protection factor (SPF) of at least 30, and reapplied every 2 hours or after contact with water,” advises Dr. Fátima.
• Physical protection: Hats, caps and sunglasses are essential. Additionally, the dermatologist recommends avoiding direct sun exposure between 10 am and 4 pm.
• Cosmetics with antioxidants: Products with vitamin C or tranexamic acid help fight free radicals, which worsen pigmentation.
• Visible light: Sunscreen with visible light protection is essential for melasma sufferers.
And what are the most recommended treatments? While the focus should be on prevention in the summer, there are treatments that can help control melasma. “Light peels, low-power lasers and depigmenting creams with medical advice can be used safely. However, the intensity of treatments is generally greater in winter, when exposure to the sun is less,” explains dermatologist Fátima.
Melasma has no permanent cure. “It is a chronic condition that requires ongoing care. Even when the spots disappear, maintaining sun protection habits is essential to avoid relapses,” concludes Fátima Tubini.
