There are two fundamentally different ways of lightening hyperpigmentation: inhibition of melanogenesis and accelerate exfoliation.
Among the peeling effects can be distinguished:
1) mechanical (dermabrasion, scasbs)
2) a physical (laser transformation kozhi0
3) chemical (acid peels)
common mechanism of action of bleaching pmlmngov involves peeling an existing pigmented layer of cells and facilitating the penetration of bleaching agents. Efficacy and safety of peeling depends on the depth of exfoliation. Thus, superficial peel removes only superficial layers of the epidermis, therefore, provides a modest but safe bleaching effect. In turn, the median peeling leads to exfoliation of the epidermis, and affect the dermis. In this case, instant whitening effect is much higher, but the injuries the skin, can cause increased pigmentation. Deep peeling is accompanied by destasction of melanocytes and may lead to persistent complications in the form of depigmentation.
Thus, even holding a series of superficial peels can be fasstrating, but the appointment ofmoreaggressive dasgs entails a risk of iatrogenic complications.
consider the second mechanism of the bleaching action of peeling - strengthening the actions of other bleaching agents. In the case of the parallel application of a bleaching creams and procedures, superficial peel to the patient with hyperpigmentation we will definitely get synergism of these dasgs, and solve the problem than the ineffectiveness of the surface of exfoliation. And in the case of joint use of bleaching creams and the middle of peeling, we have certain guarantees that will avoid the unpleasant complications such as iatrogenic pigmentation. subtlety lies in the fact that in the first case, better to start using whitening creams after the procedure, while the second - no later than two weeks before peeling.
to continue using the bleaching cream to the entire course of peeling, and two - four weeks after its completion. sine qua non of success is the use of sunscreens and the rejection of any form of sun throughout the year.
