Radiant Brightening Serum by Circadia is a lightweight brightening facial serum created for targeted care of hyperpigmentation, age spots, sun spots, and melasma. The formula helps reduce the appearance of dark spots, even the skin tone, and give the complexion a clearer, fresher, and more radiant look.

The product works with key pigmentation mechanisms: it helps inhibit tyrosinase, slow melanin production, and improve tone evenness. Thanks to its lightweight texture, the serum applies comfortably to specific pigmented areas, does not feel heavy on the skin, and fits perfectly into an evening skincare routine.

The formula combines powerful brightening ingredients and antioxidants, including ReguFade, stable vitamin C form BV-OSC, and Phenylethyl Resorcinol. With regular use, Radiant Brightening Serum helps the skin look more even, brighter, and well cared for, while dark areas become less visible.

Active ingredients action:

ReguFade (Trans-Resveratrol): a powerful antioxidant and brightening ingredient that helps visibly reduce pigmentation.

BV-OSC (Tetrahexyldecyl Ascorbate): a stable oil-soluble form of vitamin C that reduces melanin synthesis and supports a more even, radiant tone.

Phenylethyl Resorcinol (SymWhite): a strong tyrosinase inhibitor that helps brighten pigmented areas and improve skin clarity.

Who Radiant Brightening Serum is suitable for: skin with age spots, sun spots, uneven tone, and post-pregnancy melasma.

Size: 15 ml

In the evening after cleansing, apply one drop of Radiant Brightening Serum onto the fingertip and apply directly to pigmented areas only. Avoid contact with eyes.
