Cetaphil Deep Hydration 48 Hour Activation Serum

Cetaphil Deep Hydration 48 Hour Activation Serum is a lightweight hydrating serum built to correct dehydration at depth. This 1 oz (30 ml) bottle delivers hyaluronic acid — a humectant capable of holding many times its own weight in water — alongside vitamin B5 and vitamin E to soothe, replenish and protect, providing hydration that keeps working for a full 48 hours. That extended action is the point: rather than a quick surface fix, it replenishes the skin's water reserves so the look of fine dehydration lines softens and skin appears plumper, smoother and more radiant with consistent use. The silky serum absorbs instantly with no tackiness, layering cleanly under moisturiser, sunscreen or makeup. It works well for all skin types, including oily and combination skin that needs water rather than oil, and it is gentle enough for sensitive skin. Fragrance-free, non-comedogenic and dermatologist tested. Apply a few drops to clean, slightly damp skin morning and night, then seal with a moisturiser to lock the hydration in. A smart first step for tight, dull-looking skin.
