Overnight Glass Skin Duo — BIODANCE Bio-Collagen Real Deep Mask (4-pack) + COSRX Snail 96 Mucin Power Essence

COSRX Advanced Snail 96 Mucin Power Essence (100ml)

The serum that started the K-beauty revolution. With 96% pure snail secretion filtrate, this lightweight water-like essence floods your skin with hydration, accelerates overnight repair, fades post-acne dark marks, and rebuilds your skin barrier from within. It absorbs in seconds and works quietly while you sleep — every single night.

Key ingredient: 96% Snail Secretion Filtrate
Best for: Dryness · Dullness · Post-acne marks · Damaged barrier
Free from: Parabens · Artificial fragrance · Sulfates

Step 2 — BIODANCE Bio-Collagen Real Deep Mask (4-pack, 34g each)

This is not a regular sheet mask. The BIODANCE mask uses a patented 243-dalton ultra-low molecular weight collagen — roughly half the size of the 500-dalton skin absorption threshold — meaning the collagen doesn't just sit on your skin's surface, it actually penetrates deep into the dermis. As it works, the mask literally turns transparent — a visible sign that the active ingredients are absorbing into your skin in real time. Target

It also contains top-grade hyaluronic acid to hydrate and plump, probiotics to refine pores and smooth texture, and galactomyces ferment filtrate to nourish skin tone and elasticity. Formulated with non-toxic, non-irritant ingredients and free from 19 harsh or controversial ingredients — completely hypoallergenic. AmazonAmazon

How to use this bundle together:

1. Cleanse your face thoroughly and pat dry
2. Apply 3–4 drops of COSRX Snail 96 Essence and gently press into skin — wait 30 seconds for it to absorb
3. Unfold and apply the BIODANCE mask directly over your face, smoothing it flat
4. Leave on for 3–4 hours or overnight — watch it turn transparent as it absorbs
5. Remove the mask and do not rinse — the residual film contains the most concentrated active ingredients, so gently pat the remaining essence into your skin and apply your moisturizer over it to seal the effect COSRX
6. Wake up to glass skin

Use 2–3 times per week for best results. Always apply SPF the following morning.

Why this duo works better together:

The COSRX Snail Essence delivers deep repair and active hydration at the cellular level. The BIODANCE mask acts as an occlusive seal on top — locking in the snail essence while simultaneously releasing its own collagen and hydration deep into your skin. The combination of low molecular weight bio-fermented collagen and oligo hyaluronic acid creates a long-lasting plump skin effect that a single product simply cannot achieve alone. COSRX

One treatment. Two powerhouse products. Eight hours of sleep. Wake up different.
