𝘽𝙪𝙘𝙠𝙘𝙝𝙤𝙞𝙡 𝙨𝙚𝙧𝙪𝙢 "buckchoil" so it's a gentle yet effective alternative to retinol. This serum,caramel color and lightweight texture, has a somewhat chemical scent. It is easily absorbable without any heavy feelings or irritation upon use. While I haven't observed overnight changes in my wrinkles,it's a gentle serum that I hope will gradually serve as a retinol alternative. Particularly during the winter season, when rough skin and skin purging issues can arise with retinol, this buckchoil serum may come to the rescue, in my opinion.
