"Natural crystal mask sheets" generate over 120,000 monthly searches, yet many people don’t know: the key ingredient in these bouncy, essence-locking mask sheets is a North Atlantic red algae – Chondrus crispus. It solves the common pain points of traditional mask sheets (poor adherence, low essence absorption, and irritation). Below is a quick breakdown of its core value.
Unlike "adding extracts to essence," Chondrus crispus is transformed into mask sheets using its natural polysaccharide gel properties, through a 3-step chemical-free process:
-
-
Low-Temperature Polysaccharide Extraction: Select 18-month mature Chondrus crispus from the North Atlantic. Extract high-purity kappa-carrageenan (the "framework" of the mask sheet) via 45℃ water extraction to remove impurities and ensure transparency.
-
Adhesive-Free Natural Formation: Mix the polysaccharides with water at a 1:8 ratio. The polysaccharides’ natural gel network forms 0.3mm-thick mask sheets (no chemical adhesives required).
-
Freeze-Drying to Lock in Nutrients: Freeze at -40℃ to retain fucose and amino acids. When rehydrated, the sheets not only hold essence but also release active ingredients.
Compared to silk or non-woven mask sheets, it precisely addresses mask-wearing pain points:
-
Double the Essence Absorption, No Dripping: Absorbs 30ml of essence per sheet (silk sheets only hold 15ml) with 98% adherence – no waste even when worn standing up.
-
Cool Sensation + High Sealability to Boost Essence Efficacy: Delivers a 28℃ cool sensation on contact (no refrigeration needed), relieving burning within 5 minutes. The sealed environment increases essence absorption by 40%: when used with brightening essence, melanin decreases by 12% in 20 minutes (vs. only 5% with ordinary sheets).
-
Gentle & Non-Irritating, Suitable for Sensitive Skin: Has a pH of 5.5-6.0 (matching healthy skin), safe for pregnant women and post-procedure skin. The fucose in the sheets reduces sensitive skin’s Trans-Epidermal Water Loss (TEWL) by 38% after 7 days of continuous use (15% more than ordinary sheets).
Beyond holding essence, the sheet’s natural actives work synergistically with skincare ingredients:
-
Hydration & Moisture Locking: Polysaccharides absorb 500x their weight in water. Skin moisture levels jump from 25% to 68% after use, and stay at 52% for 6 hours (vs. only 35% after 4 hours with ordinary sheets) – ideal for dry environments.
-
Post-Sun Repair: The cool sensation lowers skin temperature (from 38℃ to 32℃), while iota-carrageenan reduces inflammation. Redness shrinks by 45% in 20 minutes (20% more than ordinary sheets).
-
Sensitive Skin Soothing: Chemical-free + amino acid replenishment reduces sensitive skin irritation from 60% to 15% after 2 weeks of use.
-
Anti-Aging Support: The sealed design enhances penetration of retinol/bosutin. Skin elasticity increases by 23% in 4 weeks (8% more than ordinary sheets).
