Age Defying + Restoring Formula Retinol Serum - 10 ml

@Ionelutzu
you have to contact the brand to know more about tte concentration.
It cannot be 2.5% PURE Retinol. Much too strong concentration to buy freely.

Most brands keep their formula secret due to the strong competition in the cosmetics industry. However as a customer you can always ask for clarification. 🤞🏼

@Ionelutzu how do you know this?

@amina.bdk
2.5% is too strong and forbidden to sell OTC.
This percentage is a complex of retinol and derivates and not a pure retinol concentration.

@InesSun thanks
