Melanin is the biopolymer responsible for skin and hair colour and is produced by melanocytes, cells located at the base of the epidermis and in the hair follicle. Sometimes, this melanin accumulates in certain areas of the dermis, resulting in skin spots, which are usually darker than the rest of the skin. The most common are called solar lentigines, caused by ongoing exposure to the sun, but there are also other types, such as melasma or actinic keratosis.
How can we prevent the appearance of skin spots? The first (and most important) preventive measure we should take is using a good sunscreen. Ideally with a high protection factor, which helps to block the action of UVA-UVB rays on the skin. It is also especially advisable to avoid exposure to the sun during the central hours of the day and to use accessories such as sunglasses or hats to avoid the direct impact of the sun.
Following a facial routine specifically designed for blemish-prone skin is very important to prevent the appearance or reproduction of blemishes. Anti-blemish cosmetics often contain exfoliating and depigmenting ingredients that help to soften the pigmentation and help to even out skin tone. A good facial care routine starts with an anti-spot serum to boost the action of your usual cream. Active ingredients such as Vitamin C, Glycolic Acid, Niacin or Cholic Acid are perfect for treating this type of skin. If you notice unusual looking spots or of unknown causes, it is advisable to consult a dermatologist. If your skin has actinic keratosis or many nevi (moles), you must go for a medical check-up to get them checked.
