If you protect your skin from the sun to prevent the appearance of sunspots, you are also protecting it against wrinkles and pore dilation. And without any added effort, you are preventing SKIN CANCER.
The two most frequent types of spots that appear in both women and men after sun exposure: solar lentigines and melasma, also called chloasma.
- Solar lentigines are small rounded spots with well-defined borders and different shades of brown that appear exclusively on sun-exposed areas such as the face, décolleté, back of the hands, arms and legs. Generally these spots darken in summer and lighten slightly in winter but do not disappear spontaneously. Therefore, the best treatment for solar lentigines is prevention with topical sunscreens of SPF 50+ or higher, especially in the months of April through September, both included. In addition, it is very useful to wear a wide-brimmed hat, sunglasses and an umbrella. This type of stain cannot be treated with depigmenting creams. If we want to make them disappear we will have to use more aggressive methods such as laser or freezing with liquid nitrogen.
- Melasma, chloasma or cloth are larger, brown, ill-defined spots that appear mainly on the forehead or symmetrically on the cheekbones, cheeks, upper lip or forearms. Their cause is mainly genetic and hormonal, as they may appear or worsen during pregnancy, due to contraceptives or other hormonal treatments. However, there are other important factors in its appearance such as sun exposure or emotional stress. In this case we can almost treat them with depigmenting creams at home, although they are more effective if they are supervised by a dermatologist and combined with periodic medical chemical peelings in the doctor’s office.
To avoid the appearance or worsening of melasma, chloasma or blotchiness, it is necessary to use topical sunscreens of SPF 50+ or higher all year round, even if we are not going to be exposed to sunlight. It is best to use moisturizing creams with maximum SPF 100 filters throughout the year.
