- What does this serum do?
- It is a hydrating serum built on collagen peptides, aimed at supporting firmness and smoothing the look of fine lines over time. It is not a spot treatment or a brightening serum.
- How does it compare with retinol serums?

- How should I apply it?
- Apply a few drops to clean skin before moisturizer, morning or night. Use sunscreen daily in the morning.
