So far, nothing.. doesn&#39;t irritate my skin for about 5 months of daily usage. :)

Helps keep my skin clear. I love this product. :) a must for oily skin. I use this as my toner..

So far, none.. just a slight bluish tint on my skin upon a bit thick application but that&#39;s not a concern at all for it can be washed off.. or just apply thinly... :)

I love this Buffet + Copper Peptide... i use this after microneedling with PRP.. so moisturizing and i believe this helps accelerate collagen synthesis as scientifically explained.. ;)
