This facial serum from RoC’s Hydration+ line combines hyaluronic acid with collagen proteins in a lightweight, fragrance‑free formula designed to deliver moisture and support a plumper appearance. The hyaluronic acid helps attract and retain water in the skin, while the added collagen proteins work to reinforce the skin’s natural structure, contributing to a smoother, more supple look. The serum’s texture is non‑greasy and absorbs quickly, making it suitable for daily use under moisturizer or makeup. It is formulated without fragrance, which may benefit those with sensitive skin or preferences for unscented skincare. The product comes in a 1‑ounce bottle and includes a packette of RoC Retinol Eye Cream, offering a complementary step for targeted care around the delicate eye area. The serum can be applied to clean skin in the morning or evening, followed by a moisturizer. It is appropriate for most skin types, including normal, dry, combination, and oily skin, though individuals with very sensitive skin may wish to perform a patch test before full use. The formula is free from parabens and sulfates, aligning with a straightforward skincare approach focused on hydration and skin support without unnecessary additives.
