A Korean overnight sleeping mask that shrinks pores by 73% using deep-penetration collagen technology.

Our collagen molecules are 3x smaller than typical masks, allowing them to penetrate deep into pores. Combined with ceramides that create a 'glass' finish and glycerin that plumps skin from within, you wake up with visibly smaller pores and light-reflecting skin.

1. Cleanse & pat dry.

2. Apply a thin, even layer with the brush (avoid lash/lip line).

3. Sleep → rinse A.M. Use 3–4 nights/week. Finish with moisturizer + SPF in daytime.

Yes! Our product is designed to work on all skin types, including oily, rough, acne-prone, and more, especially effective for those with visible pores, oily T-zones, or textured skin. The lightweight formula won't clog pores or cause breakouts. Whether your skin is dry, sensitive, or anything in between, you're covered!

Glycerin — Instantly plumps skin, making pores appear 73% smaller

Hydrolyzed Collagen — Creates the signature Korean "glass skin" effect overnight

Ceramide — Builds the protective barrier that keeps pores tight all day

Vitamin E — Prevents pore-enlarging oxidation

The Science Behind Your Transformation

The Problem: Traditional masks sit on your skin's surface. Their collagen molecules are too large (300+ kilodaltons) to penetrate where pores actually form - in the deeper dermal layers. The Althara Breakthrough: Our Hydrolyzed Micro-Collagen Technology breaks collagen down to 3-5 kilodaltons - small enough to penetrate deep into pore walls.

How It Works: The 3-Phase Overnight Process

Phase 1: Deep Penetration (0-2 hours) Micro-collagen molecules sink into enlarged pores while glycerin creates immediate surface plumping Phase 2: Pore Restructuring (2-6 hours) Collagen triggers your skin's natural repair process, tightening pore walls from within Phase 3: Glass Barrier Formation (6-8 hours) Ceramides create a protective "glass" layer that locks in results and reflects light

The Korean Difference

Korean skincare labs discovered that combining: 3kDa Hydrolyzed Collagen (penetrates 10x deeper) Ceramide NP (creates glass-like barrier) Glycerin + Sucrose (instant plumping effect) Overnight application (8-hour transformation window) Creates what dermatologists call the "poreless effect" - skin so smooth it reflects light like glass.

I Was Wrong About This Mask

Ok I'm usually the first to call BS on skincare miracles but my pores are literally smaller?? Like I took before photos because I wanted to prove it didn't work and now I'm eating my words. Been using it for 3 weeks, every other night. My husband asked if I got botox lol. The texture is weird at first but you get used to it.

Cheaper Than My Facials

Was hesitant about the price until I did the math - I was spending $150/month on facials trying to shrink my pores. This bottle lasts me 6 weeks and actually works better. My aesthetician asked what I've been doing differently. Glass skin is real ladies, stop wasting money on 10 different products

Finally Something My Skin Doesn't Hate

I have rosacea and everything breaks me out or makes me red. This doesn't!! Zero irritation, just smooth glowy skin in the morning. I was scared to try it but the ingredients are actually gentle. My pores around my nose basically disappeared. Only thing - use less than you think you need

- Sarah Chen, Age 32

46 and Glowing

Thought glass skin was only for 20-somethings on TikTok but wow was I wrong. This filled in my larger pores and the fine lines around my mouth are softer. Been using 2 months now. My daughter keeps stealing it from me. Wish I found this 10 years ago honestly

- Patricia Williams, Age 46

Threw Out My Ordinary Products

I've tried EVERYTHING - drunk elephant, ordinary, cerave, korean 10-steps, you name it. Nothing gave me that glass look until this. The difference is you can actually SEE it working overnight. Wake up and your skin looks blurred?? In a good way. Plus the brush makes it feel fancy. Worth every penny

My Sister Called Me a Liar

Posted my 1 week results and my sister literally thought I was using a filter. NOPE just this mask every night before bed. My forehead pores are gone and my skin reflects light now?? Started seeing changes night 3. Only annoying thing is everyone asks what I'm using and there's never enough stock lol

Everything You Need to Know About Your Glass Skin Transformation

Within the first night, you'll notice softer, more hydrated skin with a subtle glow. By week one, pores appear visibly smaller and skin texture feels smoother. After 2-3 weeks of consistent use, expect the full "glass skin" effect - poreless-looking, light-reflecting skin that looks naturally filtered. Fine lines soften, makeup applies better, and you'll need less foundation overall.

Simply cleanse your face, then apply a thin, even layer using the included K-Beauty brush (about a nickel-sized amount covers the full face). The brush helps the collagen penetrate deeper into pores. Leave on overnight - it absorbs fully so it won't transfer to your pillow. Rinse with warm water in the morning. That's it - no complicated steps.

While it works for all skin types, it's especially effective for normal to oily skin with visible pores, and combination skin with textural concerns. The lightweight formula won't clog pores or feel heavy. If you have very dry skin, you might want to apply a light moisturizer first. Those with sensitive skin should patch test, though the collagen and ceramide formula is designed to be gentle.

For the first two weeks, use it nightly to build up the glass skin effect. After achieving your desired results, maintain with 3-4 times per week. One bottle contains approximately 30 applications, so daily use gives you a full month supply. Many customers find every other night perfect for maintenance.

Most users notice improved texture overnight, visible pore reduction within 3-5 days, and full glass skin effect within 2 weeks of nightly use.

Absolutely! You can incorporate this mask into your existing skincare routine. Just ensure to apply it on clean skin and, if following with additional products, wait until the mask has fully absorbed for best results.
