№ 02 — Why Roongfah

Three quiet reasons your skin notices.

Most actives never reach the cell. Roongfah is built around the ones that do — and the climate they have to do it in.

ปกป้องผิวคุณด้วยความมั่นใจจากแบรนด์ “รุ่งฟ้า” — สูตรที่ผ่านการวิจัยจริงและขึ้นทะเบียนถูกต้อง

01
NSTDA-backed. Registered, not whispered.
Every Roongfah formula is co-developed with Thailand's National Science and Technology Development Agency (NSTDA), then filed with the Thai FDA before a single bottle ships.
02
PentaBrightyl™ — the five-active complex.
Five free-radical-trapping actives engineered in the 100–250 nm encapsulation range. Penetrates the basal layer; suppresses melanin formation; rebuilds collagen.
03
Climate-elastic by design.
Humectant-occlusive ratios tuned for Bangkok at 76 % RH and re-validated at 30 % RH. One formula. Two climates. Real-world stable.

№ 03 — Science

Why our approach matters.

Most skincare leans on marketing claims. Roongfah leans on peer-reviewed data, registered formulas and 18 months of cold-process R&D per product.

0%
of skin damage is from sun & oxidative stress — PentaBrightyl™ targets both.: 0months
in R&D per formula — extract to registered label.: 0%
sensitive-skin patch-test pass-rate, over 12 weeks.: 0–250 nm
encapsulation range — small enough to permeate, large enough to stay stable.

№ 06 — About Us

We share your lived experience.

Roongfah began with NSTDA researchers asking a simple question: could the actives in our Thai gardens hold up to peer-reviewed scrutiny?

Seven studies later, the answer is yes. PentaBrightyl™ is the five-active complex that came out of it — encapsulated, registered, and patch-tested on real Bangkok skin.
