The Two-Product Combo Behind Everyone’s “Glass Skin” Glow
If you’ve spent any time in Korean skincare corners of the internet, you’ve seen this bottle before. The COSRX Snail 96% Mucin Power Essence & Retinol 0.1% Glass Skin Starter Set pairs two of COSRX’s best-selling formulas — a snail mucin essence and a mini retinol cream — into one Amazon-exclusive kit built to hydrate, firm, and smooth skin in as little as two weeks.
It’s fragrance-free, works for all skin types, and comes in a set large enough to actually finish a routine — with a second bottle left over to share or keep as backup.
0.1% Retinol Cream
Fragrance Free
Amazon Exclusive Set
Glass Skin in 2 Weeks
Two Actives, One Complete Routine
The set includes two full-size 3.38 fl oz bottles of the Advanced Snail 96 Mucin Power Essence, formulated with 96.3% snail secretion filtrate to repair and rejuvenate skin that’s feeling dry, dull, or tired.
It’s paired with a 0.1 oz mini sample of The Retinol 0.1% Cream, designed to soften the look of fine lines and resurface skin so it looks smoother, firmer, and more radiant over time.
Hydration, Radiance, and Barrier Support
The 96% Snail Secretion Filtrate is the headline ingredient — it’s what boosts skin radiance and helps visibly even out clarity over repeated use, which is why this essence has such a loyal following.
Hyaluronic Acid & Betaine work underneath to provide long-lasting, deep hydration, while Allantoin & Panthenol help soothe any redness or irritation, keeping the routine gentle enough for daily use.
A Simple 3-Step Glass Skin Routine
After cleansing, apply 2-3 pumps of the Snail Essence and gently pat it in with your fingertips to help it absorb. Follow up with a pea-sized amount of the Retinol 0.1% Cream, massaging over any areas of concern.
Finish with your favorite moisturizer if needed. For first-time retinol users, COSRX recommends starting with a pea-sized amount just 1-2 times a week, and always patch testing before applying to the face.
Clinically Tested Results
Full Ingredient Transparency
The Snail Essence is built around Snail Secretion Filtrate, Betaine, Sodium Hyaluronate, Allantoin, and Panthenol — a short, purposeful list with no added fragrance.
The Retinol Cream adds 0.1% Retinol alongside Super Vitamin E (Tocotrienol), Panthenol, and Shea Butter to help buffer the retinol and keep the formula comfortable for beginners easing into a routine.

A Genuinely Solid Way to Start a Glass Skin Routine

With two full bottles of essence in the box, it’s generous enough to actually build a habit around, and fragrance-free enough to work for sensitive skin. A smart, low-pressure entry point into Korean skincare.
