The peach & lily glass skin refining serum has really taken hold in the US skincare market. The “glass skin” look-intensely hydrated, glowy skin with visible pores to be minimized- is still a really sought-after texture. This serum promises multi-tasking hydration, brightening, firming, and skin refining effects without any harsh actives, and I’ve been testing it out for quite some time.

Positioning in Skincare Routine
This is something that sits between toner/essence and moisturizer. Essentially this serum is designed to deliver active ingredients more deeply into the skin while moisturizing and refining your skin. “Glass skin” is not a textured based goal such as matte skin or oil-free skin, but is a skin barrier focused hydration goal that avoids harsh treatments.
What Is “Glass Skin”?
Before evaluating the serum, it is necessary to understand the concept it is built around.
“Glass skin” refers to:
- Highly hydrated, dewy complexion
- Even skin tone
- Smooth, refined texture
- Minimal visible pores
