Tidal Deep Hydration & Plumping Serum

Sunday Riley’s Tidal Deep Hydration and Plumping Serum delivers a two-phase hydration ritual. It drenches the skin in multi-layer moisture then seals it in with a breathable, water-based veil for a plump, elastic finish that feels soft to the touch. Powered by five hyaluronic acid technologies, this silky formula quenches dryness across the skin’s surface, visibly smoothing and softening for hydration that lasts.

Two molecular weights of polyglutamic acid, a next-generation humectant that holds up to five times more moisture than hyaluronic acid, draw water into the skin and create a light, cushiony seal to help lock it in. A vegan alternative to snail mucin, sourced from upcycled lotus root, helps restore bounce, improve elasticity, and refine texture, delivering a supple, smooth feel. An activated peptide solution, derived from upcycled silk, supports the skin’s natural production of claudin, a key protein that reinforces the moisture barrier to help prevent water loss and relieve tightness. Skin feels quenched, looks plumped, and springs back with bouncy, elastic resilience.

After cleansing and prepping the skin, apply 1-3 pumps of Tidal Deep Hydration and Plumping Serum to face and neck, massaging it into the skin. Can be applied morning and evening.
