I’ve been using this for 4 weeks now and have definitely noticed a difference in the fine lines around my eyes, forehead and mouth. It takes longer to absorb than other retinols I’ve tried but as it’s in an oil, it’s be be expected. One great thing about the oil is that it hydrates the skin at the same time, so isn’t as drying as other retinols. Lovely texture and once you’ve left it a few minutes it does absorb well. Ensure you use it at night and then use an SPF in the day time, due to the increased cell turn over making skin more sensitive to the suns rays.
