Why This Formula
A masterclass in nocturnal hydrologic engineering, the ISNTREE Hyaluronic Acid Water Sleeping Mask delivers deep-tier cellular rehydration through a weightless, non-occlusive aqueous gel matrix. Specifically formulated to combat accelerated nocturnal transepidermal water loss, this clinical sleep treatment forms a breathable, biomimetic moisture shield that restores osmotic equilibrium without suffocating congested or lipid-sensitive skin.
Key Ingredients
Powered by a Quintuple Hyaluronic Acid Complex spanning high, medium, and ultra-low molecular weights, the formulation achieves multi-stratum penetration—from surface-level stratum corneum smoothing to deep interstitial hydration. This hydrologic architecture is fortified with physiological Natural Moisturizing Factors (NMF) including Sodium PCA and Betaine, skin-identical Ceramide NP, and soothing Centella Asiatica to reinforce the lipid barrier and calm sub-clinical daytime micro-inflammation.
Sensorial Profile & Finish
Upon application, the translucent water-jelly quickly liquefies into a cooling, veil-like liquid that absorbs cleanly within minutes. It leaves a smooth, dewy, non-tacky finish that remains pillow-safe and breathable throughout the night, completely devoid of the greasy, suffocating film associated with conventional sleeping balms.
How to Use
As the concluding nocturnal ritual, dispense an almond-sized portion onto thoroughly cleansed and prepared skin. Smooth gently over the facial contours and neck, utilizing sweeping upward motions. Allow three to five minutes for the aqueous film to anchor into the stratum corneum prior to retiring. May be utilized nightly as a primary hydrator or two to three times weekly as an intensive restorative moisture surge over your regular treatment serums.
Good to Know
Ensure the formulation is allowed to set for at least three minutes before contact with linens to prevent friction-induced pilling or product transfer. While deeply soothing, do not apply immediately over unbuffered high-strength AHA/BHA chemical exfoliants, as sealing low-pH acids beneath an occlusive humectant network can precipitate localized erythema and barrier compromise. In arid, air-conditioned environments, always apply to slightly damp, misted, or essence-prepped skin so the humectant network pulls moisture inward rather than dehydrating deep epidermal layers.
