Serum R.

Serum R is built around trans-resveratrol and piceid: two of the most efficient plant antioxidants known to science. Combined with a stabilized Vitamin C base, the formula targets the specific pigmentation that lingers after the event that caused it: post-acne marks, sun spots, hormonal melasma, the uneven tone that skincare routines promise but rarely reach.

Resveratrol does two things that matter for pigmentation: it inhibits tyrosinase (the enzyme responsible for producing melanin) and it neutralizes the oxidative stress that triggers the enzyme in the first place. Supply the second, you reduce the first. The result is brighter, more even skin. Not bleached, just balanced.

"Surpasses other products in reversing uneven skin tone and dark spots."

Works on face, neck, and hands, anywhere pigment collects. If the serum has darkened in the bottle, it has oxidized and should be set aside. Ours rarely does, because the airless packaging prevents the oxidation that ruins most Vitamin C products.

Like Serum C, Serum R is a clean stack of actives in a non-aqueous delivery base. The addition of resveratrol and piceid turns it into something purposefully different: not just a brighter version of C, but a formulation built for a specific problem, pigmentation that doesn't correct itself.

Apply to clean, dry skin. Allow one to five minutes for the serum to absorb. Layer with Serum M if your skin needs moisture, allow to absorb completely, then continue with your daily routine. Safe for face, neck, and hands.
