(R.S.G) Cosrx retinol 0.5%oil
This is the best oil i used .it is not drying ,its a great anti aging products i have ever used ,it has reduced my fine lines ,and gave that firmness to my skin .and it also has squalane which is skin friendly ingredient which helped me in moisturising my skin .whereas retinol is sometimes drying because of squalane it doesn’t .i must say cosrx never disappoints.i started using twice a week and gradually every alternative days.
