Review: Expensive but effective - One of the best HA serums on the market and nice splurge when you want something French and fancy sounding. It hydrates and plumps fine lines as advertised without being heavy nor greasy. It does have a fragrance, but it is pleasant and mild. I was concerned it would irritate my very sensitive skin and rosacea, but pleasantly surprised after a month of daily use, zero problems. I use it in combination with the Double Repair moisturizer. My dermatologist has been pretty impressed with the health of my skin lately. In complete fairness, there are other HA serums on the market that are as effective, use the same ingredients and concentrations, at half to a quarter of the price (The Ordinary, for example.) YMMV Review: Hydrating serum that leaves skin soft and plump - I bought this serum because I needed extra hydration, especially with my busy schedule and long work shifts. The texture is lightweight but very hydrating. It absorbs quickly and leaves my skin feeling soft and smooth without being greasy. I use it before my moisturizer, and it layers well with other products. I’ve noticed my skin looks more hydrated and feels more comfortable, especially on days when it feels dry or tired. Pros: very hydrating, lightweight, smooth texture, good for daily use Cons: a bit pricey for the size Overall, this is a great serum if you’re looking to improve hydration and keep your skin looking healthy. ## Features - Ultra Hydrating Hyaluronic Acid Serum for Barrier Repair: Deeply hydrates, plumps skin to the touch, and restores the moisture barrier for a supple feel, with 91% agreeing skin feels smoother instantly. ***Consumer test, 85 subjects, 2x/day application. - Targeted Anti-Aging & Skin Repair: A super-activated hydrating serum designed to target anti-aging concerns, reducing fine lines, dehydrated skin and improving elasticity, with **1-hour skin barrier repair. **Instrumental test. - Formulated for Rich, Plump Hydration: Features pure hyaluronic acid, glycerin, and vitamin B5 for optimal hydration, rich texture, and suitability for sensitive skin.

We recommend that you mist your skin with our Thermal Spring water before use. Dont forget to lock in moisture with a moisturizer. **Q: Why is Hyaluronic Acid effective for anti aging?** A: This skincare ingredient can hold up to 1000x its weight in water, which is important considering as we age our skin loses the ability to hold onto water and stay moisturized—causing visible loss of plumpness and suppleness in our skin’s appearance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Expensive but effective *by E***C on May 5, 2026* One of the best HA serums on the market and nice splurge when you want something French and fancy sounding.
