Frequently asked questions
We've got answers
Everything you wanted to know about your nightly Glass Skin ritual.
Will this work on my skin type?
Yes — for all skin types. The application changes slightly.
Glass Skin works for dry, mature, sensitive, oily, combination and acne-prone skin. Apply over your full nighttime routine for dry/mature skin, patch test first if sensitive, avoid active breakouts on acne-prone areas, and use a thinner layer if oily.
How long does it take to dry, and will it stain my pillow?
15-20 minutes to dry. Zero pillow transfer once it's dry.
Apply your skincare, then a thin layer of Glass Skin. It feels tacky at first, then dries into a clear, comfortable film. Once dry, you can sleep face-down, side-sleep, toss and turn — it doesn't budge or stain.
How often should I use it?
3-4 nights a week is the sweet spot. Daily use is fine in dry weather or before events.
For most skin types, 3-4 nights a week gives you continuous results without over-occluding. Use nightly during dry winter months, after travel, leading up to a wedding/event, or recovering from a retinol-heavy routine.
What if it doesn't work on my skin?
Then you don't pay. Simple as that.
