Sunless tanners are cosmetic solutions based on chemical formulas that when applied directly on the skin can generate a darkening effect very similar to natural suntan. The pigment is almost identical as in the case of exposure to sun rays but the rest differs. We have the opportunity to spot out such dissimilarity when we compare artificial tanning processes, the epidermis layers affected either by DHA-based formulas or by UV rays actions. The very first difference we should bring into question is the tanning technique. There is no doubt about the fact that sunless tanners are artificial tanning solutions and the tanning effect cannot be called tan.
