If you have dark pigment spots, any self-tanner will make the spots darker yes.
As an alternative to self-tanner, we recommend that you use Perfect Skin Sun Kiss, which is a make-up product. It also gives colour, glow and sunshine to the skin - without dark pigmentation becoming more obvious.
Check out the product here.
However, our self-tanner, Perfect Skin Summer Glow, does not increase the risk of pigmentation, nor is it a problem if you have light and white pigmentation – here the product will help to hide them.
