What ONE THING Says
Product Description:
One Thing Green Tea Serum is a mild serum with original green tea (camellia sinensis) leaves, rice ferment filtrate, and hyaluronic acid to add hydration back to skin and firm skin. It has a lightweight, viscous texture that absorbs quickly without feeling sticky. Using only pure, locally grown green tea leaves, this serum takes gentle care of dryness, fine lines, and elasticity and helps you achieve plump, glowing skin. The moisturizing serum uses 16,000 ppm of pure green tea to boost the formula and hydrate skin quickly. It also uses an ideal combination of low-, medium-, and high-molecular-weight hyaluronic acid to provide abundant hydration and help moisture absorb quickly and deeply into the skin. The rice fertilizer filtrate helps reduce the appearance of fine lines and improve skin elasticity, making it appear firm and supple. In order to deliver the natural efficacy of plants to the skin as it is, One Thing applies a technology that uses whole plants. When the plant leaves that are in the serum are gently rolled and massaged into the skin, they get quickly absorbed and directly deliver maximum skin benefits. This maximizes how effective the serum is at soothing and nourishing the skin. Gentle care, potent results: Formulated with 100% plant-derived and EWG Green Grade ingredients, this vegan serum pampers even the most sensitive skin. Free from harsh chemicals, artificial colors, and fragrances, it celebrates clean, simple skincare formulas without unnecessary additions.
