Over 12 weeks of consumer testing, the new serum reduced post-inflammatory hyperpigmentation by 38%. Zero reports of burning. Zero peeling.

You have a legal, highly effective active that clears dark spots without the regulatory nightmare of hydroquinone.<\/p><p>Stop sourcing unverified powders from trading companies that do not own a single reactor.

We provide the HPLC readouts and the ultra-low heavy metal profiles that premium brands require.<\/p><p>We have lab samples ready for your formulation team to test. Put it in your next emulsion base.
