EQQUALBERRY Hyaltoin Flooding Smoothie Serum is a deep hydrating Korean skincare formulation designed to deliver intensive moisture and reinforce the skin barrier. The serum contains a multi‑hyaluronic complex consisting of 11 types of hyaluronic acid molecules of varying molecular weights, which work at different skin depths to provide layered hydration. Ectoine, a natural amino acid derivative, is included to help protect skin cells from environmental stressors, while glacier water contributes additional mineral‑rich hydration. For barrier strengthening, the formula incorporates five types of ceramides that help restore and maintain the skin’s natural lipid layer, reducing transepidermal water loss.

This serum has a lightweight, smoothie‑like texture that absorbs without leaving a heavy or sticky residue, making it suitable for daily use in both morning and evening skincare routines. It is particularly suited for individuals with dehydrated, dry, or compromised skin barriers who seek a boost in moisture and a fresher, more radiant appearance. The product is free from common irritants such as artificial fragrances and essential oils, which may benefit sensitive skin types as well.

To use, apply a few drops after cleansing and toning, and gently press into the skin before follow‑up moisturizer. The 30ml / 1.01oz bottle is designed for convenient travel and everyday use. EQQUALBERRY’s formulation prioritizes effective ingredient synergy without overpromising instant results, focusing instead on supporting long‑term skin hydration and resilience.
