Why We Formulated a Vitamin C Serum With 7 Antioxidants

Vitamin C is one of the most recommended ingredients for brightening dull skin, improving the appearance of dark spots, and supporting collagen production and for good reason. It's one of the most extensively researched antioxidants in skincare, with a reputation that's been built over decades.

Yet vitamin C is only one part of a well-formulated serum. The ingredients around it matter just as much, shaping everything from how the formula holds up over time to how it supports skin throughout the day. Among them, antioxidants play a particularly important role, each contributing in its own way to a more complete formula.

Why Isn't Vitamin C Alone Enough?

Sure, vitamin C deserves the hype. It's one of the most studied ingredients in skincare. But here's the thing: skin doesn't experience just one kind of stress. Sun exposure, pollution, and even normal cellular processes all generate different forms of oxidative stress. Expecting one antioxidant to take care of all of it is a bit like expecting one player to carry an entire team. That's why thoughtful formulas are built around a network of antioxidants rather than a single star ingredient.

Not Every Antioxidant Does the Same Job

We tend to lump antioxidants into one big category, as if they're all doing the exact same thing. They're not. Just because two ingredients are antioxidants doesn't mean they behave the same way. They interact with skin differently, respond to oxidative stress differently, and contribute to a formula in different ways.

Some are particularly good at neutralizing certain types of free radicals. Others are better at supporting the skin after it's been exposed to everyday environmental stress. Some even help improve the overall performance of a formula. They all belong to the same family, but each brings something different to the table.

Inside the Formula: Why We Chose These Antioxidants

Karma Boost Vitamin C + Antioxidant Serum pairs vitamin C with seven carefully selected antioxidants that complement one another and the formula as a whole.

Liposomal Vitamin C

Vitamin C was always going to be the foundation of this formula. It's one of the most well-researched ingredients in skincare, known for visibly brightening skin, supporting collagen, and helping improve the appearance of uneven skin tone.

We chose a liposomal form of vitamin C because it helps deliver the ingredient more effectively while being gentler on the skin.

Liposomal Niacinamide

Niacinamide has earned its reputation as one of skincare's most versatile ingredients, which is exactly why we wanted it alongside vitamin C. While vitamin C focuses on brightening and antioxidant protection, niacinamide helps support the skin barrier, improve texture, and visibly even out skin tone.

Using a liposomal form also helps improve compatibility with the rest of the formula, making it a natural partner in an everyday antioxidant serum.

Micellar Vitamin E

Vitamin E has been paired with vitamin C in skincare for decades and for good reason. Together, they're one of the most well-studied antioxidant combinations, helping skin better defend itself against everyday environmental stressors than either ingredient can on its own.

We chose a micellar form of vitamin E to help integrate it seamlessly into the formula while complementing vitamin C's antioxidant activity.

Micellar Resveratrol

Resveratrol is a powerful antioxidant found naturally in plants like grapes and berries. We included it because it expands the formula's antioxidant support, bringing strengths that go beyond vitamin C alone.

Using a micellar form also helps improve its compatibility within the formula, allowing it to work alongside the other antioxidants more effectively.

White Tea Extract

Not every antioxidant comes from a single isolated ingredient. White tea naturally contains a rich mix of protective plant compounds, bringing another dimension to the formula.

We included it because botanical antioxidants add diversity to the antioxidant blend, helping create a formula that reflects how antioxidants exist in nature, not just in a lab.

Licorice Root Extract & Amla

Licorice root helps promote a more even-looking complexion, while amla is naturally rich in antioxidant compounds that have been valued in skincare for generations.

Together, they round out the formula with botanical support, adding another layer to the overall antioxidant blend without simply repeating what the other ingredients already do.

How to Get the Most From Your Antioxidant Serum

For most people, the best time to apply a Vitamin C antioxidant serum is in the morning.

After cleansing, apply your serum before moisturizer, then follow with a broad-spectrum sunscreen. While antioxidants help defend against oxidative stress, sunscreen remains your first line of defense against UV damage.

Using your antioxidant serum every morning gives your skin daily support against the environmental stressors it encounters throughout the day.
