Currently back on s+m and on baby dose of 0.006% tret plus azelaic acid and niacinimide. Think it's the anti ageing pathway.
If you say dark spots are your biggest concern what else can they offer? Same but stronger or different ingredients entirely? I actually think my uv damage ages me far more than wrinkles, and most of mine are dehydration rather than 'true' wrinkles.
Thanks
