What skin type am I?
Skin type can be determined by factors such as skin and hair color, freckles and nipple color. In general, the lighter the skin, hair and nipples and the more freckles you have, the shorter the skin’s own protection time.
However, these are only indications and do not allow an exact skin type analysis, as the percentage of eumelanin in the skin is decisive. This eumelanin content can and should be determined by a visit to your dermatologist.
Only then can you say with absolute certainty what skin type you are.
