What are the key ingredients of the Black Serum and how do they work?

Peat Water tightens and minimizes the appearance of pores while unclogging and boosting elasticity. Niacinamide (3%) amps up the pore-tightening effect, brightens and evens out skin tone, and regulates oil production. Hyaluronic Acid and Arginine lock in moisture, deliver long-lasting hydration, and leave your skin smooth and soft. It’s like a power team for your pores and glow!
