Yes — but how you use it matters.

Glass Skin works for all skin types, but the application changes slightly:

• Dry / mature skin: Apply over your full skincare routine including a rich moisturizer. The mask seals everything in — without that base layer, you'll wake up tight.
• Sensitive skin: Patch-test first on your jawline for one night. If you feel tightness or burning at any point, peel it off and rinse — don't push through.
• Acne-prone skin: Avoid applying directly over active, inflamed breakouts. The occlusive seal can intensify a flare. Apply on healthy areas of skin around them.
• Oily / combination skin: Apply a thinner layer. You don't need much — your skin is already producing its own moisture.

Bottom line: this isn't a moisturizer. It's a sealant that locks in everything underneath. Treat it like the final step, not the only step.

15-20 minutes to dry. Zero pillow transfer once it's dry.

Apply your skincare, then a thin even layer of Glass Skin. It'll feel tacky for the first few minutes, then dry into a clear, comfortable film. Once it's fully dry, you can sleep face-down, side-sleep, toss and turn — it doesn't budge, doesn't transfer, doesn't stain.

If you're impatient: apply it 20 minutes before bed and it'll be set by the time your head hits the pillow.

Same idea, completely different experience.

Slugging works — but it's greasy, gets in your hair, ruins your pillowcase, and you can't target specific areas. Glass Skin gives you the same occlusive sealing benefit but:

• Dries clean — no grease, no transfer
• Targeted application — apply only where you need it
• Peels off cleanly in the morning
• Won't clog your pores like petroleum-based slugging can

Think of it as slugging, evolved. Same science. Better experience.

3-4 times 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.

• Night 1: Plump, dewy, glass-skin glow in the morning
• Week 1: Skin feels more bouncy, makeup applies better
• Weeks 2-3: Smoother texture, fine lines from dehydration look softened
• Week 4+: Stronger barrier, sustained hydration, a baseline glow that doesn't fade

Honest answer: both.

Here's what Glass Skin will do:

• Lock in your existing skincare for 8 hours of uninterrupted absorption
• Create a hydration shield that stops moisture loss overnight
• Plump fine lines caused by dehydration
• Deliver a visible glass-skin glow by morning

Use it for what it actually is: the most efficient overnight glow + hydration tool you'll add to your routine. Not a miracle. A multiplier.

Because it's filled to 80% capacity for shipping safety. You're getting the full 75ml.

The mask is air-pressure sensitive — fully filled tubes can rupture or leak during international shipping.

Then you don't pay. Simple as that.

We back every tube with our 60-day glass skin guarantee. Apply it nightly for 60 days. If you don't wake up to plumper, dewier, glass-like skin — send the empty tube back and we'll refund you in full.
