If I use Differin at night, do I have to lubricate my face with sunscreen during the day and how do I combine the use of this cream with the Soolantra drug that I apply in the morning?

When using Differin cream, as a result of reducing the stratum corneum of the epidermis, the skin becomes more sensitive to the effects of ultraviolet radiation, so during the treatment you should avoid excessive exposure to UV radiation and sunlight - using, for example, a headdress and protective filters. Sunscreen should be applied about 15-30 minutes after Soolantra cream or just before leaving home. Please note that sunscreens work for up to several hours and require reapplication during the day.
