Overview
A capsule-form facial serum from HKH combining bakuchiol, HPR retinol, and jojoba oil with red clover (Trifolium) and sea fennel extracts, formulated without alcohol.
The listing gives little beyond its ingredient panel, so it stands or falls on that. Pairing bakuchiol with HPR retinol is a way to bring a retinol-adjacent effect to skin that may not tolerate straight retinol alone, cushioned by jojoba oil. The capsule format usually means single-use, pre-measured dosing rather than a pump bottle.
- Capsule (single-dose) item form
- Bakuchiol and HPR retinol blend
- Jojoba oil, Trifolium, and sea fennel extracts
- Alcohol-free, scented formula
Who it's for
Aimed at anyone looking for a retinol-alternative serum built around bakuchiol and a jojoba oil base, in a scented, capsule-dosed format. Not for buyers who want an unscented or fragrance-sensitive formula, since this one is listed as scented.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines bakuchiol with HPR retinol
- Single-use capsule dosing
- Scented, not suited to fragrance-sensitive skin
- Listing gives no usage frequency or application guidance
Performance notes
Bakuchiol and HPR (hydroxypinacolone retinoate) are both retinol-adjacent ingredients, generally chosen as gentler alternatives to standard retinol. Jojoba oil in the base is there to cushion the actives, while the formula is listed as alcohol free.
