I recommend Innisfree Cica Cream.

Because I have sensitive skin, I often experience redness, breakouts, or itching if I apply the wrong product, especially before my period. I kept switching between different cosmetics, and one product I really liked was Amphigel. It is an aloe gel that I purchased from a dermatologist, and I found that applying only that definitely soothed my skin. However, it was a bit expensive, so I couldn't keep buying it. Recently, I discovered Innisfree Cica Cream. Since Innisfree and Amore Mall have been having big sales lately, I bought it at a really, really low price. It applies very smoothly and feels as smooth as melted candle wax. Also, because my skin is sensitive, I usually get itchy or a burning sensation immediately, but with this product, I don't feel anything at all after applying it; I only feel a moist, hydrating sensation. So, I plan to keep using only this. I highly recommend it to anyone with sensitive skin.
