RoC Hydration+ Hyaluronic Acid Face Serum 1 oz — 7 Forms HA, 72‑Hour Hydration

RoC Hydration+ Hyaluronic Acid Serum is a concentrated, dermatologist‑inspired face serum that instantly hydrates and visibly plumps fine lines using seven forms of hyaluronic acid and Pro‑Collagen amino support.

If your skin feels dehydrated, looks creased, or needs a smoother, refreshed appearance, this lightweight 1 fl oz serum is formulated to deliver rapid moisture and a fuller look without heaviness. Developed with dermatologists and built on RoC’s decades of skin research, the formula pairs multiple molecular weights of hyaluronic acid with collagen‑supporting amino acids and a patent‑pending Dual‑Fill Technology designed to attract and retain water in the skin for up to 72 hours of clinically measured hydration.

How quickly will I see lines appear less noticeable?

Many users notice a visible refill to the look of fine lines within minutes because the blend includes seven hyaluronic acid variants that sit at different skin levels. Immediate smoothing is often seen right after application, with progressive improvement as the skin's moisture balance improves.

• Fast‑absorbing milky texture that layers under moisturizer and makeup
• Seven hyaluronic acid forms for multi‑depth hydration
• Patent‑Pending Dual‑Fill Technology to boost visible plumping

Will this serum work for oily or sensitive skin without clogging pores?

The serum is formulated to be lightweight, fragrance‑free, non‑comedogenic and hypoallergenic, making it suitable for oily and sensitive skin types when used appropriately. Apply a smaller amount to slightly damp skin and allow absorption before adding other products to avoid a heavy or greasy finish.

• Fragrance‑free and paraben‑free formula designed to minimize irritation
• Non‑comedogenic so it won’t clog pores when used as directed
• Tip: press into damp skin and wait ~60 seconds before layering

How does this serum support longer‑term skin texture and resilience?

Beyond immediate hydration, the formula contains Pro‑Collagen amino acids that aim to support the skin’s natural collagen network over time. With regular use, users report smoother, plumper‑looking skin, as the combination of sustained moisture and collagen support helps maintain elasticity and surface evenness.

• Pro‑Collagen amino acids support skin’s structural proteins (does not contain collagen)
• Clinically measured hydration that can last up to 72 hours
• Suitable for daily AM and PM routines to build cumulative effects

How should I incorporate this into my skincare routine?

Apply a few drops to clean, slightly damp skin after cleansing and before moisturizer, sunscreen or makeup. Adjust the amount depending on skin type—use less for oily or combination skin—and press gently until absorbed. For daytime, follow with sunscreen; for nighttime, pair with your regular moisturizer or treatment products.

• Use morning and evening for best cumulative results
• Start with fewer drops and increase as needed for comfort
• Allow about a minute for full absorption before layering other products

Who is this for: RoC Hydration+ Hyaluronic Acid Serum is aimed at anyone seeking intensive, non‑greasy hydration and a visibly plumper complexion—particularly those dealing with dry patches, early fine lines, or loss of youthful fullness. It’s suitable for people with normal, combination, oily, or sensitive skin who want a dermatologist‑inspired serum that layers easily into morning and evening skincare routines.
