The right sunscreens to prevent and treat sunspots

When talking about sunspots it is necessary to make a distinction between them, also because there are spots that can be treated with aesthetic-medical treatments and or prevented and others that cannot. We have solar lentigo and simple lentigo that cannot be treated with a depigmenting agent because in these spots, in addition to the presence of melanin, there is also the presence of melanocytes and therefore they cannot be removed. We also have post-inflammatory hyperpigmentation spots, melasma or chloasma that, being composed only of melanocytes, can be treated with depigmentants and prevent them from worsening with excellent sun protection. Let's take a look at each spot individually so that we have an idea of how to recognize them.

We have the solar lentigo that can be recognized because it has a generally circumscribed shape and a uniform color, but sometimes it can be slightly pigmented inside, they are generally and mostly found in older people who have exposed themselves disproportionately to the sun without sunscreen.

- Then we have the simple lentigo that look a little like freckles, are small spots and frequent both on the face and body.

It is very important to obtain medical advice for the treatment and identification of these spots since some of them may over time turn into melanomas and become dangerous. Therefore, it is absolutely recommended not to treat them with depigmenting agents since, not only will they not go away, but they may become irritated.

Post-inflammatory hyperpigmentation spots can be generated as a consequence of acne, aggressive peeling or pimples. Since there are no melanocytes and they are created due to inflammation, it is possible to obtain results with depigmenting agents and it is also possible to prevent them from getting worse and darker.

While melasma or also called chloasma is created by an excess of hyperpigmentation and by an imbalance in the synthesis of melanocytes, it can be found in an age range between twenty and fifty years old and can arise due to hormonal therapies, use of contraceptive pills or during pregnancy and in this case it can be defined as a mask of pregnancy, melasma can improve a lot with depigmentation but in some cases there is also the need for laser.

The sunscreens that we are now going to see do not act as real lightening treatments since, it is important to remember that their main action is to protect from the harmful rays of the sun but, in part, they can help not only to prevent these hyperpigmentations from getting worse but also to improve their appearance.

The first protector recommended in case of hyperpigmentation is Anthelios Age Correct with SPF 50 by La Roche Posay, composed of niacinamide, which helps the inhibition of melanin, helps against sun redness and, in case of sensitive skin or skin with couperose, helps to avoid excessive skin redness; vitamin E which has an antioxidant action and hyaluronic acid which helps moisturize the skin or in case of dry skin, helps prevent it from increasing dehydration with sun exposure.

Next we have another really good sunscreen that can also help in the treatment of spots and is the Bioderma Photoderm Spot Age with SPF 50 + which has a strong antioxidant action is composed of vitamin C known for its depigmenting action apart from antioxidant and vitamin E excellent against free radicals.
