@noura.ayoubi: Hyaluronic acid = hydration. It’s a humectant that helps attract and hold onto water, making skin look smoother, plumper, and more hydrated. Pro tip: apply it to slightly damp skin and follow with moisturizer to help seal that hydration in. A few options I like: - CeraVe Hydrating Hyaluronic Acid Serum @CeraVe - La Roche-Posay Hyalu B5 Serum @LaRochePosayUS - Vichy Minéral 89 (LOVE THIS) @Vichy Laboratoires - The Ordinary Hyaluronic Acid 2% + B5 @The Ordinary - Neutrogena Hydro Boost Hyaluronic Acid Serum @Neutrogena And remember, you don’t necessarily need a separate HA serum. It’s already included in plenty of good moisturizers #skincare #hyaluronicacid #hyaluronicacidserum #moisturizer
