How does it act
They normalise the skin around the hair, make the skin cells or keratinocytes less sticky ( cohesive) so that follicle opening is not obstructed and there is no back head or whitehead formation. It softens the skin and decreases stickiness so it can be easily shed and does not accumulate. Since they cause shedding of the dead skin layer, they also improve penetration of other agents applied with it such as antibacterial or anti-inflammatory. It is usually combined with clindamycin, benzoyl peroxide or salicylic acid.
Tretinoin also causes a reduction and even distribution of melanin, thus helping in mottled hyper-pigmentation and lentigines.
