SK-II - Heehee review for Facial Treatment Essence with 90% Pitera

I purchased this awhile ago. Got excited and purchased two of these during a sale. I saw it got promoted by many celebrities, and have high expectations for this. It's extremely lightweight and refreshing on skin. The slightly fermented scent is acceptable, nothing pungent. I like how it's hydrating and gave me the luxurious user experience. The pitera essence is skin brightening and hydrating. Though I don't see much improvement in wrinkles and dark spots, mainly the essence brighten the skin tone. My skin does feel more healthy after this, and weirdly my skin also feel less oily. I have been soaking this essence with cotton pads and leave it on skin for a few minutes to really optimize the results - more hydrated skin.
