Two of skincare's most proven brightening ingredients — Centella Asiatica and Vitamin C — working together in one targeted serum. The Beauty of Joseon Light On Serum is designed specifically for uneven skin tone, dark spots, and post-acne hyperpigmentation, combining the brightening power of Vitamin C with the calming, barrier-supporting properties of Centella to deliver results without irritation.

The challenge with Vitamin C serums is that they're often either too unstable (degrading quickly and becoming ineffective) or too irritating for sensitive skin. This formula addresses both: it uses a stabilised form of Vitamin C alongside Centella Asiatica to buffer any potential sensitivity, making it suitable even for skin that has struggled with other Vitamin C products. The Centella also works on its own to reduce post-inflammatory hyperpigmentation — the red or brown marks left after breakouts — meaning both ingredients are actively working toward the same goal.

The lightweight serum texture absorbs quickly, sits comfortably under moisturiser and SPF, and is gentle enough for daily use.

Sul Skin note: An excellent pairing if you want to target uneven skin tone without the irritation risk of a standalone Vitamin C serum.
