I have come to expect nothing but the best results from OKOKO as every product purchased has become a favorite. After falling in love with the original Les 16 Précieux and placing an order for my third or fourth bottle this spring, I received this version as a gift. Because of the retinol, I put off trying it until this month as my skin is very sensitive to the sun and I would be incorporating it into a nighttime routine that already includes an Adapalene treatment and a couple targeted retinol treatments. After just two evenings, my skin felt more taught and was noticeably smoother in the morning. I did have a tiny bit of flaking around my cheeks but knew this was my skin getting accustomed to the additional retinol. A week and a half later, my skin is more radiant, clearer and smoother to the touch. It looks like this will be my Winter/Spring evening serum and the original version will work for Summer/Autumn months. I encourage anyone looking for a skincare routine that delivers results quickly to invest in OKOKO. The prices may seem high, but only a tiny amount of each bottle or jar will deliver amazing results for many months.
