I'm in my early-mid 20s with combination/dry skin, and I began using this essence almost a year and a half ago and I've never stopped. This essence has transformed my skin in so many ways but, first and foremost, it helped fade my hyperpigmentation/minor acne scars in addition to making my skin glow - something I began noticing after just a few weeks of using it. Over the year, I've used this essence in my daily routine and I've noticed that it has helped prevent breakouts (I only have a breakout very occasionally in comparison to the past). There was a short period of time (a couple of weeks) during which I didn't have this essence with me and I had noticed that my skin tone seemed duller, which made me realize that this essence was a major factor in helping my skin maintain a healthy glow.

FYI: Although I use the serum on a daily basis, it usually lasts several months (atleast 4-5 months). It's not super hydrating but it works well for my combination skin and absorbs fairly quickly as well. If you are wondering whether to purchase this product or not, I would definitely recommend it - it transformed my skin and lived up to its holy grail status from my experience.
