❤️ crepes, but not crepey skin 😢 Options: @anua_global retinol, @SOMEBYMI ID retinol, @COSRX US , @LaRochePosayUS lipikar, @@differin Adapalene. So you can actually the retinoid right to the body, it is sometimes very irritating. Body skin is less forgiving than facial skin. Sandwich method also works :) Yum. Questions? And be patient: need 3-6 months for results #Skincare #hack #dessert #crepes #dermatology
