Etude House Thermal Black Cleanser

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (ceteth-25, oleth-10, peg-120 methyl glucose dioleate, polysorbate 20, sodium cocoyl glutamate, sodium lauroyl glutamate, xanthan gum) and should be able to cleanse the skin gently. Still keep in mind that any cleansing can disrupt the skin barrier, and most people do not need to cleanse their skin more than once per day.

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: glycolic acid.

This product contains ingredients (glycolic acid) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.
