I use this after toner and before my serums, no dramatic changes yet (only on week 2) but no averse effects.

Lots of skin caring peptides love it 😀

Lovely serum use as part of my daily skincare AM & PM great under make up 

I think this product is really good value for money. I put it on after I have cleansed and top off with moisterizer. I have very dry skin so this works a treat! A real gem so glad I found this product

I love the Cosrx snail mucin power essence so I decided to give this new peptide skin booster serum and try and I will definitely be repurchasing. It is a thin water like serum and on reading reviews you use it as the toner step (directly on skin) in your skin care regimen. It has left my skin plump and hydrated but not oily. It mixes well with other products and can be used day and night. Can't wait to see the longer term results.
