Recommendation for RETINAL line use
For retinoid beginners:
Recommended to start using only 1 product containing retinoids (including retinal) in your skin care routine.
For experienced retinoid users:
Combine 2-3 retinal liposome products in your skincare routine, e.g. 2% serum with 1% moisturizer or 4% eye cream with 1% moisturizer.
