ISNTREE Hyper Retinol EX 1.0 Serum 20mL is a lightweight, milky serum designed to refine the look of fine lines while helping skin feel firmer and smoother. It absorbs quickly into the skin, making it an elegant treatment step for a focused evening routine.
 
This formula pairs retinol and retinyl palmitate with bakuchiol, peptides, ceramides, and TECA to support a more refined, resilient-looking complexion without a heavy finish. Ideal for those introducing a higher-performance retinol serum, it is best used gradually to help skin adjust.
 
How to use: After toner, apply 2-3 drops to the face in your nighttime routine, starting slowly and increasing use as tolerated. Use sunscreen the next day.
