This retinol and HPR serum from HKH is formulated for nighttime use, designed to support the skin’s natural renewal process. The product comes in capsule form, each containing a measured dose of serum intended to reduce waste and maintain ingredient stability. The formula combines retinol with HPR (Hydroxypinacolone Retinoate), a retinoid ester known for its gentler profile on the skin compared to traditional retinol, making it suitable for those new to retinoids or with sensitive skin. Peptides are also included, which are commonly used in skincare to support the skin’s structural proteins.

The serum targets visible signs of aging, such as fine lines and wrinkles, while working to improve skin firmness and tightness. It is non-greasy upon application, absorbing quickly without leaving a heavy residue, which suits normal, combination, and oily skin types. The capsule packaging is travel-friendly, allowing for easy portability without risk of spillage or oxidation. This product is intended for use as part of a nightly skincare routine, typically applied after cleansing and before moisturizer. It is suitable for women seeking a straightforward anti-aging treatment that prioritizes ingredient delivery and convenience. The formula avoids common irritants in many retinoid products, aiming to provide visible results with reduced redness or peeling. As with any active skincare ingredient, gradual introduction is recommended to assess individual skin tolerance.
