If you've ever tried AHA acids and want to increase the percentage you use, this is the toner for you. It contains 5% AHA acids —glycolic acid and lactic acid—, which chemically exfoliate the skin, improving its texture and promoting skin cell renewal. If you have very sensitive skin and you've never tried an acid, a gentler toner (like this one) is a great starter.
Pour a small amount of toner to your fingers and apply to your face by gently tapping the skin. Remember: try not to pull on your skin! If you prefer, you can also use a cotton pad, though Koreans never do that. Why? To avoid swiping the cotton pads over the skin, generating unnecessary waste and wasting toner (as pads soak up most of the product). Also, by using your fingers, the temperature of the toner will be similar to that of your skin.
It's one of the products with the highest content of AHA available at MiiN Cosmetics.
