Overview
HKH serums01 packages retinol, vitamin C, vitamin E, hyaluronic acid and collagen into single-use capsules meant for application after cleansing. The alcohol-free, fragrance-free formula is positioned for all skin types.
Capsule serums keep the formula sealed in individual pods rather than an open pump bottle, which protects light- and air-sensitive actives like retinol and vitamin C until the moment you break one open. The tradeoff is fixed dosing per capsule, and the listing does not state how many capsules the package contains.
- Capsule (single-use pod) format
- Retinol, vitamin C, vitamin E, hyaluronic acid, collagen
- Alcohol free and fragrance free
- Intended for use after cleansing
Who it's for
Suits someone who wants several common actives (retinol, vitamin C, E, hyaluronic acid, collagen) combined without assembling a multi-step routine, and who prefers fragrance-free, alcohol-free formulas. Not for buyers who want a refillable bottle they can dose freely.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines five common active ingredients in one product
- Sealed capsules protect actives from air and light
- Fragrance free and alcohol free formula
- Listing does not state capsule count or price per use
- No customer review data available to confirm results
Performance notes
Listing retinol alongside vitamin C, vitamin E, hyaluronic acid and collagen points to a broad anti-aging formula rather than a single-ingredient treatment. Sealing each dose in its own capsule is a common way to protect retinol and vitamin C, both of which break down with repeated air and light exposure in an open bottle.
