Unfortunately, the Neulii serum has the consistency of aloe vera gel, and provides no exfoliation, whatsoever. However, if your skin is particularly sensitive to BHA products, I can see this being useful when applied after your BHA--to soothe the skin.

Surprisingly, I have oily, acne-prone skin, and rather enjoy the CosRX mask. The texture is somewhat bouncy, and, when applied lightly before bed, leaves my skin with a supple feeling in the morning. When applied heavily, however, my face becomes somewhat greasy. (A heavier application would be ideal for dry, or dehydrated skin, I believe.)

**I experienced no blemishes from either of these products.
