FAQs

Q1. How does the Cetaphil Optimal Hydration 48H Serum sustain hydration for 48 hours with just a twice-daily application?
A1. The serum uses a layered humectant system — hydrolyzed hyaluronic acid, sorbitol, and glycerin — that draws moisture from the environment and binds it at multiple depths within the epidermis. This reservoir effect sustains hydration between applications, rather than simply coating the surface.

Q2. What is hydrolyzed hyaluronic acid, and is it more effective than regular hyaluronic acid?
A2. Hydrolyzed hyaluronic acid has been broken down into shorter molecular chains, allowing it to penetrate into the upper layers of skin rather than sitting on the surface. This deeper action makes the Cetaphil Optimal Hydration Serum more effective at plumping from within, compared to serums using only standard high-molecular-weight HA.

Q3. Does this serum replace a moisturiser, or should it be layered under one?
A3. For most skin types, it works best layered under a light moisturiser — the humectants draw moisture in while a moisturiser on top seals it. In humid climates like Mumbai or Chennai, many users with normal to oily skin find the serum alone is sufficient without an additional moisturiser.

Q4. Is the Cetaphil Optimal Hydration 48H Serum suitable for oily or acne-prone skin?
A4. Yes. It is non-comedogenic, fragrance-free, and paraben-free, with a fast-absorbing formula that does not leave a greasy residue. The sunflower seed oil used is high in linoleic acid, which helps regulate sebum composition rather than clogging pores.

Q5. Can it be applied before sunscreen and makeup without pilling?
A5. Yes — it layers smoothly under SPF and foundation. Allow 1–2 minutes after applying the serum before adding other products to ensure full absorption and prevent pilling.
