Discover your shortcut to true Glass Skin.
The Milky Collagen Duo transforms dull, tired skin into a luminous, mirror-like glow — effortlessly.
Inspired by advanced Korean skincare, simplified into two intelligent steps: a deeply hydrating serum and a collagen-infused lock-in mask.
In just 20 minutes, your skin feels smoother, firmer, and visibly more radiant.
No filters. No 10-step routines. Just real, touchable glow.
Your skin — refined to perfection, glowing like glass.
How To Use?
+
Step 1 – Milky Serum
After cleansing, apply 2-3 drops to the face and neck.
Massage gently until the milky texture fully absorbs — your instant drink of glow.
Step 2 – Collagen Mask
Apply an even layer over the skin.
Allow 20–30 minutes for the invisible film to set.
Peel away softly to reveal hydrated, dewy glass skin.
Use 2–3× per week or whenever your skin needs that effortless, luminous boost.
The ultimate lazy girl secret to Korean-style radiance.

"I’ve never seen my skin look this smooth before. After just one use, it felt hydrated and had that glassy glow I’ve been chasing for years. The serum sinks right in, and the mask seals it perfectly — my skin literally drinks it up. Even makeup sits better now. I’ve cut my 6-step routine down to this duo, and I’m obsessed."
Lauren,

“I thought glass skin was just an Instagram filter — until I tried this duo. Within minutes, my skin felt deeply hydrated and alive. The glow wasn’t greasy or fake, just smooth, firm, and naturally reflective — the first time I looked in the mirror and thought, that’s my real skin.”
Alex,

Verified Buyer
“After the first use, I finally understood what glass skin actually means. My skin looked hydrated from within — not shiny, but smooth and light-reflective. The serum feels milky and cooling, and when the mask locks it in, it’s like you can feel your skin repairing itself. I woke up with this even, translucent glow that no moisturizer ever gave me. It’s simple, clean, and it just works.”
Sophia,

Verified Buyer
“I’ve never felt this confident barefaced before. My skin used to look tired and uneven, but after using the Collagen Duo, it’s like it came back to life. The glow looks hydrated, not oily — that fresh, almost translucent finish I thought only pros could get. Every time I use it, my skin feels firmer and smoother, like a real reset. I’m obsessed with how calm and balanced it feels now.”
Megan,

Verified Buyer
“I have super reactive skin, so most ‘glow’ products just made me red or greasy. But the Collagen Duo is totally different. It strengthens my barrier instead of stripping it, and my skin feels calm — like it finally found its balance. The glow is soft, hydrated, and even-toned, not shiny. I love that it only takes 20 minutes, yet my skin stays radiant for days. It’s honestly replaced three steps in my old routine.”

Immediate glow, but not greasy
I used this before a dinner event and was honestly shocked. My skin looked brighter and firmer after just 20 minutes, but not oily or shiny like some masks. The booster serum really makes a difference — my skin felt plump and smooth even the next day. Definitely repurchasing.
Feels like a facial at home
I’ve tried a lot of collagen masks and most are just temporary glow. This one actually made my skin feel more hydrated and bouncy, not just shiny. I love that it’s a 2-step system — the serum + mask combo feels very intentional and luxe.
Perfect before makeup
I used this the night before a big event and my makeup went on SO much smoother the next day. My skin looked calm, hydrated, and noticeably more even. I usually get redness after masks, but this didn’t irritate me at all.
Worth it for the results
At first I thought it was just another glow mask, but this actually gave longer-lasting results. My skin felt hydrated for days, not hours. The milk texture is really soothing, and I like that it doesn’t sting or tingle.
You can tell it’s higher quality
Everything about this feels premium — from the packaging to the way my skin feels after. The booster serum absorbs quickly and the mask seals everything in perfectly. My skin looked firmer and more refreshed after just one use.
Frequently Asked Questions
Find answers to common questions about our products.
Will this really give me Glass Skin?
+
Yes, but not the fake oily kind.
The MilkyBump Collagen Duo works beneath the surface, hydrating and strengthening the skin barrier while boosting collagen production.
You’ll see visibly smoother, plumper, light reflective skin after just one use, and it only gets better with consistency.
How fast will I see results?
+
You’ll notice a visible glow and bounce within 20 minutes of your first session.
With continued use, fine lines soften, texture refines, and your skin tone looks more even with a clarity that no filter can fake.
How do I place an order? Is it safe for sensitive or breakout prone skin?
+
Absolutely.
The formula is dermatologist tested and non comedogenic, using gentle yet powerful actives like Niacinamide, Milk Extract, and Low Molecular Collagen.
It balances oil, calms irritation, and supports your skin barrier instead of stressing it.
Do I still need my regular skincare routine?
+
Not necessarily.
The Collagen Duo is designed as a two step shortcut to Glass Skin and replaces multiple products like serums, creams, and overnight masks.
You can simplify your routine without losing results and even see better ones.
What makes this different from Korean “Glass Skin” products?+
+
Traditional glass skin routines rely on eight to ten layering steps that mostly stay on top of the skin.
Osli's Collagen Duo takes a clinical European approach by boosting collagen, hydration, and elasticity from within the barrier.
It is a smarter, modern way to achieve clean, dewy clarity without the complexity.
How often should I use the Collagen Duo?
+
For best results, use it two to three times per week.
Think of it as your skin’s reset ritual.
Each session deeply hydrates, smooths, and recharges your barrier, keeping your glow consistent and long lasting.
Is it clean and cruelty free?
+
Yes. Osli's Milk Collagen formulas are vegan, cruelty free, and free from parabens, sulfates, alcohol, and synthetic fragrance.
Every ingredient is chosen for efficacy, tolerance, and transparency so your glow comes from science, not silicone.
