Some background on my skin before I review my experience with the product: I have combination skin: oily in the T-zone, dry everywhere else, and sensitive skin around my mouth and chin (only discovered this recently).

I received a travel size set (balancer, emulsion, and gel cream) at a local retailer during one of their promotions. I was really excited to try The History of Whoo and this skincare line. The packaging is cute, the product contains a light fragrance, and the product is absorbed quickly.
Unfortunately, this product contains denatured alcohol (aka alcohol denat.), which I did not know at the time that would cause severe dehydration and flakiness on the sensitive part of my face.

I tried the travel set of products one morning and all seemed well until the afternoon. I was experiencing some itchiness and irritation around my mouth and chin, but didn't think anything of it. Fast forward another hour or so and the irritation has become worse. I got home from work and that area was inflamed and was noticable reddish-pink color. I immediately wash off my face, pat dry and put on some aloe to reduce the reaction. For the following 1.5-2 weeks, the skin around my mouth and chin is super dry and flaky. My lips were also chapped as a result of the denatured alcohol disrupting my moisture barrier.

On the non-sensitive parts of my face, the balancer absorbed well and did not dry me out. It made my skin feel soft and lightly moisturized. I wasn't oily in my T-zone or dry on my cheeks. It was a great base to begin applying essences, serums, emulsions and creams. After using the rest of the travel size on my cheeks and forehead, I would say that this is a decent product. However, for those with sensitive skin or a history of adverse reactions to alcohol denat., steer clear of this product/skincare line as most (if not all) of the Soo SooYeon (aka Super Hydrating line), contains denatured alcohol.
