Sunlight stimulates the production of melanin which acts as a natural protection because it absorbs a wide range of UV rays. The result is a natural tan. Excessive exposure of the skin to the sun can disrupt this process and cause improperly shaped pigmented foci - hyperpigmentation. Restricted and controlled, especially direct sun exposure and regular application and replication of funds with a high protection factor is a key factor in combating them.
Although many day creams have a protection factor of less than 30, in the summer months it is not enough for maximum protection and therefore it is necessary to use products with a protection factor of 30 - 50 +. The products should be applied at a distance of about 2 hours, and not applied only once.
