1 / 7The Hyaluronic Acid 3 Serum
A straightforward hydrating serum built around a 3% blend of hyaluronic acid. It sinks in quickly and leaves skin feeling plump and comfortable rather than sticky, so it fits easily into a morning or evening routine. A good pick if your skin often feels tight, dry, or dehydrated.
More detail
The formula pairs 3% sodium hyaluronate, which draws water into the skin, with skin-identical amino acids and ceramide NP that help hold onto that moisture and support the barrier. The texture is light and watery, absorbs fast, and finishes smooth without a tacky film. Apply a few drops to clean skin at the serum step, morning and night, then follow with moisturizer to lock it in, and it layers fine under sunscreen or makeup. It's fragrance-free and gentle enough for sensitive or easily irritated skin. There's little to complicate it, which is much of the appeal.
