Which would you say you have had the best results from? My concerns are uneven skin and aging - large pores, but if my skin would be smoother, it may help apply make up to conceal these.
Skin and me have said I can have a slightly higher starting point of retinal, 0.018 in relation to 0.015 Dermatica.
They have both said 4% azaelic acid and 4% niacinamide.
