“The COSRX AHA/BHA Refresh Vitamin C Lip Plumper volumizes, smooths and hydrates dry and chapped lips.”

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: betaine salicylate.

What the product description says
“It’s a lightweight gel-cream that can easily be scooped with your fingertips and softly melts on your lips for an effortless, smooth application that turns dry lips hydrated and dewy.”

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: butyrospermum parkii butter, diisostearyl malate.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: petrolatum
