Functional Actives - Key Ingredients

Liponic EG-1

Betaine

A naturally occurring amino acid that helps regulate water balance within the skin, keeping cells hydrated. Provides soothing benefits while reinforcing water levels. Ideal for helping the skin maintain plumpness and suppleness.

Hyaluronic Acid (L Sodium Hyaluronate)

A deeply hydrating, biomimetic form of hyaluronic acid that binds water to the skin, plumping fine lines and improving suppleness of the skin. Its smaller molecular size supports hydration through multiple layers.

Shea Butter (Butyrospermum Parkii Butter)

A rich, nourishing lipid source that helps deeply moisturise and soften the skin. Supports visible smoothness, reinforces the skin’s protective barrier and helps prevent moisture loss during sleep. Ideal for restoring comfort to dry or compromised skins.

How It Works

Hydra Plus Sleep-In Mask combines biomimetic hydrators and lipid-rich nourishing actives to restore moisture balance and rejuvenate the skin overnight.

L-Sodium Hyaluronate draws water into the skin to improve plumpness and smooth dehydration lines, while Betaine supports balanced water flow within the skin for lasting softness. The Core Four peptides and antioxidants help support collagen performance, brighten tone and defend against glycation, contributing to improved radiance and long-term skin longevity. Skin wakes refreshed, supple and visibly renewed.
