Sun Serum
SPF 50+ in a texture that behaves like an essence rather than a sunscreen. This is where Korean formulation leads most clearly, and it addresses the real reason people skip sun protection: not doubt about the need, but dislike of how conventional sunscreen feels.

Available directions
Formulation directions this product type can be developed in. Pick one during your request, or ask us to advise during matching.
Watery
The signature Korean sun texture, absorbing like an essence rather than a sunscreen.
Hydrating
Humectant-rich so daily SPF also serves as a hydration step.
Cooling
A fresh finish aimed at hot and humid target markets.
Lightweight
Minimal residue for consumers who reject conventional sunscreen feel.
Mineral sun serum
Zinc-based in a watery base, technically the hardest version to formulate.
Key ingredient options
UV filter system
Modern filters carried in a watery base, the hardest sunscreen texture to formulate.
Hyaluronic acid
Reinforces the skincare positioning so the product doubles as a hydrating step.
Centella asiatica
Calms daily UV exposure and supports the sensitive-skin angle.
What makes it work
- The category where Korean formulation leads most clearly. An SPF 50+ product that genuinely feels like an essence.
- Solves the core adoption barrier, since people skip sunscreen mainly because of how it feels.
- Layers invisibly under makeup, which supports daily-wear and reapplication habits.
- Sunscreen availability, testing and target-market compliance require separate manufacturer confirmation. US sunscreen must be reviewed as an OTC project.
Texture & format
Watery essence-like fluid delivering SPF 50+ with an almost undetectable finish.
Frequently asked
Is a sun serum as protective as a cream?
Yes when applied at the same quantity. The SPF rating is validated by the same third-party testing regardless of texture. The lighter texture is a formulation achievement, not a compromise on protection.
What makes this hard to formulate?
Carrying enough UV filter load to reach SPF 50+ in a watery base while keeping it stable, non-tacky and cast-free. It is one of the more technically demanding briefs in Korean suncare.
