It's the only product that worked.

I have a dark spot above my upper lip that has, for years, simply refused to fade. I've slathered serums, and even employed a pigmentation-pummeling laser or two to no avail. It wasn’t until I discovered the Mela B3 Serum from French pharmacy favorite La Roche-Posay that said mark began to budge.

The La Roche-Posay Mela B3 Serum is a dark spot-treatment that fades the appearance of all types of hyperpigmentation — including post-inflammatory hyperpigmentation (i.e. dark marks from ghosts of pimples’ past), sun spots, and melasma. The serum is lightweight, non-sticky, and layers well beneath other skincare products, making it an easy solution to incorporate into any existing routine, and a targeted means of addressing dark spots and general unevenness.

For a limited time, the product is on sale at Amazon for $34.

While myriad hyperpigmentation-quelling solutions exist, La Roche-Posay’s latest formula features an entirely novel pigmentation-fighter — a molecule called melasyl, which was developed over 18 years of research, per the brand. Niacinamide — a tone-evening, pore-whittling form of vitamin B — is also present in the formula, and supports the brightening effects of the elixir’s primary hero ingredient.

While I’m often skeptical of products that seem to overpromise, this serum absolutely delivers on its dark spot-annihilating claims; it’s already made a substantial impact on the aforementioned hyperpigmentation spot I’ve struggled to fade over the past three years or so. After about three weeks of using the serum consistently — a dab or two, directly over the dark mark in question — I’ve noticed a subtle yet substantial difference in its prominence. Naturally, I’m looking forward to lessening its appearance even more as I continue using this truly remarkable serum.

Shoppers have noticed similarly speedy results from using La Roche-Posay’s dark spot solution. According to one, the formula has “really helped” their “uneven skin” after only two months. Another fan, who has dealt with post-inflammatory hyperpigmentation after adult chickenpox left marks, says the serum has rendered their dark spots “invisible” after only one bottle.

For a targeted hyperpigmentation-fading solution that truly works — and rapidly, too — snag La Roche-Posay’s Mela B3 Serum at Amazon while it’s on sale for a limited time.
