I've struggled with dark spots and uneven tone for years. After adding this to my routine, my skin started looking brighter, smoother, and more even. I kept getting asked what I changed. I'm so happy I didn't undergo laser, as I know it may leave spots on your skin. bioBare is my go to forever!
I had a large dark spot on my cheek that always bothered me and felt impossible to cover completely. After using this consistently, I started noticing my skin looking brighter and more even. When I compared my photos, I was honestly shocked at the difference. My skin just looks healthier overall. I was honestly shocked at the difference. My skin just looks healthier overall.

I didn’t realize how dull and tired my skin had started to look until I compared photos. The dark marks seemed more noticeable over time and my skin just felt flat.

Vitamin C is famously unstable. Most serums sitting on a shelf for a year are already oxidized before you open them. That's why we make THE C in small batches by hand, ship within weeks of production, and cap each run to protect the 20% L-Ascorbic Acid potency.
Every bottle you receive is as fresh as the day it was formulated.
Most vitamin C serums fail in five ways. We fixed all five.
Most "premium" serums run 15% vitamin C - the bare minimum to make the claim. The C. is formulated at 20% pure L-ascorbic acid, the active, ready-to-use form your skin recognizes on contact. More active vitamin C, doing more work, from the first drop.
Vitamin C is unstable on its own. Without the right partners, it oxidizes and loses strength fast. bioBare locks it in with the proven C + E + ferulic trio for stability and daily UV defense - then adds vitamin B and hyaluronic acid for hydration and barrier comfort, so it stays effective and gentle enough for every skin type, sensitive included.
Many brands sit at pH 4.0–5.0 because it feels gentler - but above 3.5, vitamin C can't penetrate. It just sits on the surface and evaporates. bioBare is stabilized at pH 3.1–3.4, the clinically proven window where vitamin C actually gets in.
Vitamin C is fragile, so, light, air, heat, and time break it down. A serum mass-produced and warehoused for months can lose real potency before it ever touches your skin. bioBare is made in small batches and shipped fresh, weeks from being made, not last season's stock oxidizing in a warehouse.
The gold-standard vitamin C framework is decades old and no secret. Luxury brands still charge $150–$185 for 15%. bioBare gives you 20%, plus B and HA, made fresh - for a fraction of the price. More serum, more actives, less markup.

You shouldn’t have to become a chemist, inspect a factory, or wonder how long a bottle sat in inventory to know whether your skincare was made well.
That should be our responsibility, not yours.
When I started bioBare, I wanted to build the kind of skincare company I would trust as a customer. One that cared just as much about what happens behind the scenes as what ends up on the label.
That philosophy eventually changed the way we make THE C.
L-Ascorbic Acid is exceptionally sensitive to time, heat, light and air. And after years of relying on traditional large-scale manufacturing, I became uncomfortable with how much of that process, production timing, storage, batch consistency, and time in inventory, was outside our control.
So we brought that control closer.
Today, THE C is produced in smaller, more frequent batches so we can keep a much closer eye on its journey from production to your skin.
You may never see that part of the process.
But we believe the things you don’t see are often the things that matter most.
I know you might still have doubts. You've probably tried 3, 4, 5 other Vitamin C serums that promised everything and delivered nothing. You've spent more than $39 on a moisturizer that did less. I get it. That's why we offer a 60-day empty-bottle guarantee. Use the entire bottle, and if it doesn't work for you, send the empty back. Full refund. No questions.
Maybe in 8 weeks, you'll be one of the customers who emails us saying "I wish I'd started this sooner." We get that message every week. Take a before photo today. Compare it in 8 weeks. That's how I want you to judge us.
Vitamin C is one of the most powerful skincare ingredients available - but it's also one of the most delicate. Over time, exposure to light, air, and heat can reduce its effectiveness and cause formulas to darken.
That's why we produce our Vitamin C, B, E & Ferulic Serum in small batches rather than manufacturing massive quantities months in advance. This allows us to maintain tighter quality control and deliver fresher products to our customers.
While many brands produce huge production runs that may sit in warehouses for extended periods, our small-batch approach helps ensure every bottle reaches your skin as fresh as possible.
The $39 is our special introductory offer. But even at $58, you're paying for the formula and not celebrity endorsements, luxury retail markups, expensive packaging, or massive advertising budgets. We also have sales events every couple of months, with 20%-25% discounts for our loyal customers to stock up.
Our Vitamin C, B, E & Ferulic Serum contains 20% L-Ascorbic Acid along with Ferulic Acid, Vitamin E, Niacinamide, and Hyaluronic Acid - the same core ingredients people seek out in much more expensive formulas. We simply believe effective skincare shouldn't require spending nearly $200 on a single bottle.
Many customers tell us their skin looks brighter, more hydrated, and noticeably glowier after the first application. More visible improvements in dark spots, uneven tone, fine lines, and overall radiance typically become noticeable after 3-8 weeks of consistent use. Like any skincare product, results depend on your skin, your routine, and how consistently you use it - but most people don't finish their first bottle wondering if it's working.
Yes. Our Vitamin C, B, E & Ferulic Serum was designed to fit into most skincare routines. It pairs beautifully with hyaluronic acid, peptides, moisturizers, and sunscreen. If you're using retinol, AHAs, or BHAs, we generally recommend applying Vitamin C in the morning and stronger exfoliating products at night to minimize the chance of irritation - especially if you're new to active ingredients.
Because this formula contains a potent 20% L-Ascorbic Acid, some people - especially first-time Vitamin C users - may experience a mild tingling sensation during the first few applications. This is normal and usually temporary. The formula also contains Vitamin E, Ferulic Acid, Niacinamide, and Hyaluronic Acid to help support skin comfort and hydration. If you have extremely sensitive skin, we recommend starting every other day and gradually increasing usage as your skin adjusts. We also highly recommend a patch test if you're concerned about irritation.
Our formula does not contain retinol or hydroquinone, which are commonly avoided during pregnancy. However, every pregnancy and breastfeeding journey is unique, so we always recommend consulting your physician before introducing any new skincare product.
For best results, apply it in the morning after cleansing and before moisturizer and sunscreen. Vitamin C helps defend against environmental stressors throughout the day. Many customers also use it at night, but if you're choosing just one time, the morning application is our recommendation.
A single bottle typically lasts about 6 weeks with daily use. Most customers use 3-4 drops per application. If you're serious about improving dark spots, uneven skin tone, and visible signs of aging, we recommend at least a 90-day consistency window, which is why our multi-bottle bundles are the most popular option.
Simple. Use the serum every day. If you don't love your results, contact us within 60 days of delivery and we'll refund your purchase - even if the bottle is completely empty. No complicated forms. No arguing with customer service. No need to send back a full bottle. We want you to try it long enough to decide whether it's right for your skin, completely risk-free.
