Hyaluronic acid serum works by drawing moisture from the environment into the skin, making it one of the most widely used hydrating actives in daily skincare. Because hyaluronic acid occurs naturally in the body, it suits most skin types, including sensitive and combination skin, and can be applied morning and evening without disruption to other steps. The range at Ronaghan's Pharmacy includes established options such as Vichy Mineral 89 Hyaluronic Acid Hydrating Serum, which layers well under moisturiser, and L'Oréal Revitalift Filler formulations that combine hyaluronic acid with daily and overnight cream formats. For those looking to pair actives, a vitamin C and hyaluronic acid serum used in sequence supports both brightening and hydration goals. Always read the product label before use, and speak to our pharmacist if you have any questions about incorporating a new serum into your routine.
