Bio-C Vitamin C Serum with Niacinamide

If your skin looks tired, uneven, or just needs a reset, Bio-C Vitamin C Serum is built for exactly that. It uses a gentle, stable form of vitamin C called 3-O-Ethyl Ascorbic Acid, paired with niacinamide, glycerin, and sodium hyaluronate. Together, these ingredients brighten dull skin, calm redness, and add lasting hydration, without the sting that stronger vitamin C formulas often cause.

What This Serum Does for Your Skin

• It fades dark spots and evens out skin tone. The vitamin C in this serum slows down the process that creates dark spots and sun marks. With regular use, most people see real change in their skin tone within four to six weeks. This isn’t an overnight fix, but it’s a steady one.
• It calms and balances your skin. Niacinamide strengthens your skin barrier and helps control extra oil. Over time, skin looks calmer and reacts less to daily stress like weather changes or makeup.
• It hydrates without feeling heavy. Sodium hyaluronate and glycerin pull moisture into your skin and hold it there. Your face feels soft and full, not tight or greasy. This serum sits comfortably under moisturizer or makeup.
• It helps skin look healthy and refreshed. Antioxidants in the formula protect skin cells from daily stress like pollution and screen time, both of which can leave skin looking flat. Regular use keeps your complexion looking fresh.
• It’s gentle enough for daily use. 3-O-Ethyl Ascorbic Acid is one of the calmer, more stable forms of vitamin C available. If pure vitamin C serums have burned or stung your skin before, this is worth trying instead.
• It fits into any routine. One dropper, used once or twice a day, is enough. No mixing, no measuring, no extra steps.

What to Know Before You Buy

Honesty matters more than hype here. This serum doesn’t contain SPF, so it isn’t sun protection on its own. It also doesn’t contain ferulic acid or vitamin E, so we’re not claiming the added stability boost some premium serums advertise. And since the formula doesn’t include peptides or retinoids, we’re not making firm anti-aging or collagen claims either. What you’re getting is a focused brightening and hydrating serum that does what it says, nothing more, nothing less.

Shipping and Refund Policy

Orders ship within one to two business days, with standard delivery taking five to seven days. If the serum isn’t right for your skin, return it within 30 days for a full refund, no complicated process required. Damaged or incorrect orders get a free replacement within seven days of contact, no return shipping needed first.

We’d rather refund you than have you keep a product that isn’t working.
