During the summer, the skin glows thanks to the sun, but it can also suffer from a less desirable effect: the appearance of dark spots , often concentrated on the face, décolleté, and hands. These discolorations, called sunspots , are caused by irregular melanin production in response to UV rays.
The good news? They can be prevented and treated effectively, especially with targeted skincare, rich in depigmenting and even-looking active ingredients .
Why do sunspots appear?
Sunspots form when melanocytes , the cells responsible for producing melanin, overreact to solar stimulation. The causes can be:
- prolonged exposure to the sun without adequate protection
- discontinuous use of sunscreen
- hormonal changes (pregnancy, pill, menopause)
- previous skin inflammations (post-acne, dermatitis)
- photosensitizers (poorly managed drugs or cosmetics)
How to really prevent them
-
Sunscreen is the first treatment
Often overlooked, consistent daily sun protection is the best anti-blemish skincare investment. Even in the city or on cloudy days, UVA rays penetrate and stimulate melanin production.
2. Antioxidant serum in the morning
Combining vitamin C and SPF is a powerful weapon. Vitamin C neutralizes free radicals generated by the sun and helps even out skin tone .
How to treat them with functional active ingredients
If the spots have already appeared or tend to return every summer, it is essential to introduce lightening and rebalancing active ingredients into your routine:
Niacinamide (Vitamin B3)
It reduces excessive melanin production, calms inflammation, and strengthens the skin barrier. It's also perfect for sensitive skin.
Tranexamic Acid
Increasingly used for its anti-inflammatory and depigmenting properties, it targets stubborn stains without sensitizing them.
Azelaic Acid
Multifunctional: reduces discoloration, refines skin texture, and fights bacteria that cause mild acne. An excellent ally for combination skin.
Mandelic Acid
A gentle exfoliant that stimulates cell turnover without irritation. Helps gradually lighten blemishes and improve radiance.
Retinoids
They stimulate cell turnover and reduce the appearance of dark spots. However, be careful: they should only be used at night and always combined with a high SPF.
Extra tips for a complete action
- Consistency: Brightening active ingredients take time. The first visible results appear after 3–6 weeks.
- Avoid aggressive scrubs: they can worsen discolorations and sensitize the skin.
- Constant hydration: A strong skin barrier helps prevent recurrences.
Sunspots aren't an inevitable fate , but the result of poor skincare habits. With a targeted strategy that combines prevention (SPF + antioxidants) and treatment (gentle active ingredients), skin can regain an even, radiant, and visibly healthier appearance .
Choose effective yet skin-friendly formulations, like those from Reysense , designed to accompany you in every season with simplicity and visible results.
