This is one of my 2020 empties skincare. All i could say this just my cup of tea that helps me fighting with my acne and over production of sebum. It contains 2% of Lactic Acid - types of alpha hydroxy acid (AHA), which in short chemical exfoliant. Plus, it has bigger molecule than glycolic acid - that it’s not as strong on the skin, making it a better option for sensitive because it only targetting the top layer of the skin.
This toner doesnt leave any stickiness or feeling tight. also, absorb superb fast as soon as you pat it on your face.
It contains denatured alcohol.
If you want to be cautious of alcohol denat to begin with, but because it does increase the penetration of other ingredients, be especially wary of products where it's combined with other potential irritants, such as fragrance.
