No matter what skin type you may have, Vitamin C is one of the most impactful ingredients you can incorporate into your daily skincare routine. Whether you’re looking for an all-over boost of radiance, a strong defense against sun damage, or a powerful brightener for dark spots, vitamin C can help you effectively achieve all these skin goals, and more.
The wide-ranging benefits of vitamin C in skincare are a major reason why this ingredient is so beloved throughout the beauty community. However, it’s multitasking abilities can make vitamin C a bit confusing to understand: What’s the best way to start using it in your skincare routine? Which form of vitamin C is best for the specific skin concern you want to target? When should I use vitamin C in my skincare routine?
In this guide, we share everything you need to know to become an expert in this superstar ingredient. We’ve even included a breakdown of our three vitamin C-centered formulas, explaining how they differ and how you can incorporate both into your daily routine.

What Is Vitamin C in Skincare?
When used in skincare, Vitamin C is a powerful antioxidant that can fight free radicals, visibly brighten, reduce the appearance of hyperpigmentation, and boost the skin’s firmness by jumpstarting collagen production.
You can spot vitamin C on an ingredient label in a few different forms. It may be listed as any of these: magnesium ascorbyl phosphate, L-ascorbic acid, tetrahexyldecyl ascorbate, ascorbyl palmitate, ascorbyl glucosamine, and ascorbyl tetraisopalmitate. (More on the forms we use in our formulas below.)
The Benefits Of Vitamin C For Skin
As an antioxidant, VItamin C can help offset skin-damaging UV rays, pollution, dust, and debris by neutralizing free radicals. Vitamin C provides powerful anti-aging benefits to skin including:
How do Biossance’s Vitamin C Skincare Products Differ?
Three of our top-performing formulas – the Squalane + Vitamin C Dark Spot Serum, Squalane + Vitamin C Rose Moisturizer, and Squalane + Vitamin C Rose Oil – feature this prized antioxidant as a hero ingredient. Each works in dramatically different ways to achieve dramatically different results for your skin. Are they interchangeable? Definitely not. Can you use all three in your routine? Absolutely. Here are four key ways these formulas differ–and one important thing they have in common.
Treatment vs. Moisturizer vs. Oil
The primary way these three formulas differ is that they’re each designed to be used during different steps of your skincare routine. Our Squalane + Vitamin C Dark Spot Serum is a treatment. With a powerful dose of actives and a touch of squalane for balance, this product is hyper-focused on targeting one main skin concern: dark spots.
Our innovative Squalane + Vitamin C Rose Moisturizer also targets dark spots. But unlike a serum whose key purpose is to treat, this moisturizer’s principal task is to nourish and moisturize your skin. Think of it as a moisturizer with treatment benefits meant to amplify your anti-aging skincare routine.

On the other hand, our best-selling Squalane + Vitamin C Rose Oil is formulated to deliver glowing hydration to the skin, delivering our uniquely oil soluble, shelf-stable Vitamin C to boost radiance while locking in moisture and driving active ingredients deeper in to the skin.

2. The complementary ingredients create different results
Vitamin C’s benefits can be amplified and diversified depending on how concentrated it is and what other ingredients it’s paired with. For example, our Squalane + Vitamin C Dark Spot Serum blends a powerful dose of 10% vitamin C with white shiitake mushroom extract. When this high concentration of vitamin C is paired with this discoloration-correcting plant extract, it boosts vitamin C’s ability to powerfully and visibly reduce the appearance of established dark spots while also preventing new ones from forming.
In this delicately balanced treatment, we use ethyl ascorbic acid, a unique shelf-stable form of vitamin C that’s known to be less irritating than other forms on the skin while still being highly effective. Our scientists found that a 10% dose of L-ascorbic acid is the ideal amount needed to deliver fast, powerful, long-lasting results.
Our Squalane + Vitamin C Rose Moisturizer packs a powerful one-two punch of Vitamin C and fermented lemon peel to dramatically reduce the appearance of dark spots while also targeting fine lines and wrinkles. It features our unique and trusted form of shelf-stable vitamin C called tetrahexyldecyl ascorbate (THD) which is know for its outstanding ability to penetrate the skin and absorb quickly. In consumer surveys, 100% of participants saw increased radiance and visible improvement in fine lines, wrinkles, and dark spots with regular use.
In our best-selling face oil, vitamin C teams up with an exclusive blend of sugarcane-derived squalane, Chios crystal oil, and Damascus rose extract to deliver a broad range of balanced benefits–namely hydration, increased radiance, and a boost of firmness. We also use THD as our form of vitamin C in this formula as it is uniquely oil-soluble. This way, you get the benefits of an oil alongside next-level glow.
3. Squalane plays a different role in each formula
Our sugarcane-derived squalane also plays quite a different role in these top-performing vitamin C formulas. In our Squalane + Vitamin C Rose Oil, squalane takes center stage, delivering a fresh dose of fast-absorbing, weightless hydration.
In our Squalane + Vitamin C Moisturizer, squalane delivers deep hydration, strengthening the skin’s moisture barrier while driving active ingredients deeper into the skin.
In our Squalane + Vitamin C Dark Spot Serum, the weightless oil plays more of a supporting role, allowing the 10% dose of L-ascorbic acid to take the lead while it works in the background to keep skin happy, healthy, and hydrated while helping actives penetrate.
4. They’re all formulated to last
One key commonality between these three formulas is that they all feature shelf-stable forms of vitamin C. As popular as this ingredient is, it also has a tendency to break down quickly through a process know as oxidation. When vitamin C oxidizes, it loses its effectiveness and can also cause irritating side effects. Our scientists have specially formulated both of our vitamin C products to be extremely stable so that they can continue to provide clean, healthy, skin-loving no matter how fast or slow you may use them.

As a lifestyle writer and journalist, I’m excited to bring my passion for storytelling to Biossance as an Engagement Content Writer. Two things you should know about me: I have a deep love of the ocean (especially sharks) and I’m obsessed with clean beauty. My bathroom cabinet is literally overflowing with my many-layered sustainable skincare routine. This combo is what led me to buy my first bottle of Vitamin C Rose Oil. I was so impressed by the way it improved my skin that I wanted to shout this brand from the rooftops. Three years later, and here I am doing just that. I’m excited to be on this journey of clean beauty innovation with Biossance, and to share it with you here on the blog.
