I've been struggling with hormonal acne in my 30's and didn't want to change my entire skin care routine to target acne, as I'm not usually prone to it and don't have an oily skin type. This targets specifically the type of acne I'm dealing with, but has properties to address my other skincare issues as well. Bonus: it's super moisturizing, which I wasn't expecting. I'm sure an oilier skin type could use it alone as a serum/moisturizer combo. I've been combining it with the bamboo firming fluid and it's a perfect amount of moisture for my skin in the mornings.
