well i found if i do use primer, i don't get any spots etc ..well cleanser, toner, after caffeine solution 5% + egcg (reduce dark circles), hyaluronic acid 2% + b5 (hydrate ), cream with SPF, we have just one skin so we should take care of. for nigh have i have retinol or vitamin C, caffeine again, oils and night creams, to be honest i wasn't intro skin care at all, but getting older, thinking about investing more to my self, and i have to say i see huge difference.
