Three questions we hear
What does a booster do?
It is a light first layer that hydrates and helps the products after it spread more evenly.
Can I use it with retinol?
Yes. It is gentle and works well as a hydrating layer around retinol.
When will I see results?
Hydration is immediate; firmness and fine lines take weeks of daily use.
