What is better for anti aging? Tretinoin 0.5% or tazarotene 0.1%? What can be used? AHA or BHA? Any advice on how to apply the retinoid? I only know it should be applied to clean dry skin at night. Can i mix it with lotion or cream? Can i put a moisturizing cream or hyaluronic acid over it? I have noticed most dermatologists have flawless skin which i am assuming its from their daily topical skin care routine and trying their lasers? Any serums or moisturizer you would recommend? Physical or chemical blocks? (I have a beard and physical sunscreen makes beard all white). Currently i use cetaphil cleanser, caudalie premier cru le serum, Dermaceutic Tri Vita C30 - 30% Vitamin C Serum, sun screen. Nocte i only use tazarotene without any moisturizer. Thanks in advance.
