Serum
The most direction-flexible product in Korean skincare and the highest-volume treatment category its factories produce. A single proven base can be taken toward hydration, tone, firming or regeneration, which is why most brands launch here first and extend the line with trend actives later.
Production terms are confirmed directly with the matched manufacturer.
Available directions
Formulation directions this product type can be developed in. Pick one during your request, or ask us to advise during matching.
Hyaluronic hydration
Multi-weight HA hydrating at different depths. The most universally sellable serum.
Panthenol barrier support
High-percentage panthenol for barrier repair, with no irritation ceiling.
Niacinamide oil control
4 to 10 percent niacinamide with zinc, the best-evidenced sebum-regulating system.
Vitamin C brightening
Stabilized derivatives that survive export shipping where pure ascorbic acid oxidizes.
Tranexamic acid and alpha-arbutin
Targeted tone correction for stubborn discoloration and post-inflammatory marks.
Peptide firming
Signal and carrier peptides, the ingredient family with the strongest search demand.
Retinal or retinol renewal
Encapsulated retinoids balancing efficacy against irritation, a Korean specialty.
PDRN regeneration concept
Salmon-derived polynucleotide, one of Korea's fastest-rising premium actives.
Exosome concept
Next-generation regenerative positioning drawing on Korean dermatology research.
Spicule renewal
Micro-spicule physical delivery, a distinctly Korean resurfacing technology.
NAD/NMN vitality concept
Longevity-adjacent positioning, currently trending in premium Korean development.
Bi-phase oil serum
Two visibly separated layers shaken before use, protecting incompatible actives.
Key ingredient options
Multi-weight hyaluronic acid
Three to eight molecular weights hydrating from surface film to deeper layers.
Niacinamide
Sebum regulation, tone and barrier support in one well-tolerated active.
PDRN
Salmon-derived polynucleotide used for regeneration and repair positioning.
Encapsulated retinal
Delivers retinoid activity with materially less irritation than free retinol.
What makes it work
- The highest-volume treatment category in Korean OEM production, which means proven bases and fast sampling.
- One hydrating base can carry almost any trend active, so a line can extend without new development risk.
- PDRN, exosome and spicule directions are where Korean labs currently lead the world.
- Packaging is part of the formulation decision for vitamin C and retinoid directions, since both degrade with light and air.
Texture & format
Concentrated fluid with a fast-absorbing finish, layered under moisturizer and tuned per active system.
Frequently asked
Which serum direction should a new brand launch first?
Hyaluronic hydration is the safest hero SKU. It suits every skin type, carries no irritation risk, and the same base can later be extended with peptide, PDRN or exosome versions from the same manufacturer.
Why use vitamin C derivatives instead of pure ascorbic acid?
Pure L-ascorbic acid oxidizes quickly, turning brown and losing potency across long export shipping. Korean factories favour stabilized derivatives that stay effective in the bottle.
