What makes this product unique?
Resist C15 Super Booster is a concentrated blend of 15% stabilized vitamin C (l-ascorbic acid), antioxidant vitamin E, ferulic acid, and peptides. Resist Pure Radiance is a technologically-advanced brightening formula that contains a proprietary complex of proven vitamin- and plant-based ingredients.

When used together, this power couple supercharges your anti-aging routine. They repair visible signs of aging and stimulate collagen production for smoother, brighter, and more radiant skin. Continued use, coupled with daily application of sunscreen, will prevent discolorations from coming back and keep new discolorations from appearing.

These products are 100% fragrance- and colorant-free.

Who is this product for?
Resist C15 Super Booster and Resist Pure Radiance Skin Brightening Treatment are targeted treatments for all skin types, including those prone to blemishes. It's specially formulated for anyone struggling with brown spots, uneven skin tone, and a dull complexion.

How quickly will I see results?

Your skin will take on a more luminous, smoother look instantly. With daily use, you can expect to see an improvement in uneven skin tone and brown spots within weeks. As with any product meant to improve discolorations, daily use of a sunscreen rated SPF 25 or greater is essential to achieve optimal results. Ongoing use is necessary to maintain results and keep new discolorations from forming.

Is it OK to mix the Resist C15 Super Booster and the Resist Pure Radiance Brightening Treatment with my sunscreen?

No, you should never mix any skincare product with a sunscreen because it will dilute the sunscreen, making it less effective. For best results, mix Resist C15 Super Booster with the Resist Pure Radiance Brightening Treatment each morning and follow with your daytime moisturizer with sunscreen. In any daytime skincare routine, sunscreen should always be the last product applied.

Is the Resist C15 Super Booster and Resist Pure Radiance Brightening Treatment duo suitable for breakout-prone skin?

Yes! The vitamin C in the Resist C15 Super Booster plus antioxidants and repairing ingredients in both products work to reduce the inflammation and redness from acne, as well as encourage healing of red marks from past breakouts.

Is the Resist C15 Super Booster and Resist Pure Radiance Brightening Treatment duo suitable for rosacea-affected skin?

Maybe. The concern is the amount of vitamin C in the Resist C15 Super Booster, which can be too potent for some cases of rosacea. We suggest sampling this product to see how your skin responds. Generally speaking, though, vitamin C’s anti-inflammatory action on skin can be helpful for rosacea.

Resist Pure Radiance Skin Brightening Treatment should be effective and suitable for someone with rosacea. However, those with rosacea always need to be careful about any skincare product they use because even the gentlest formulas may cause a reaction.

Is Resist C15 Super Booster and Resist Pure Radiance Skin Brightening Treatment duo safe for all ethnicities?

Yes. Both are safe and provide brightening benefits for skin of any color or ethnic background.

My skin tends to be sensitive to vitamin C but I still want to use the Resist C15 Super Booster. Will applying this product a few times per week still be beneficial?

Yes. Although once- or twice-daily application is recommended, you will absolutely still see benefits from Resist C15 Super Booster if it’s applied less often. As with any skincare product, you should pay attention to how your skin responds and adjust usage (or products) accordingly.

I received my C15 and the internal air restrictor isn’t in the bottle—it’s on the dropper. How do I insert it?

The internal air restrictor, as you noticed, is now packaged separately to reduce the likelihood of the bottle leaking during transit. There are two ways to insert it into your C15, and both are easy!

Option #1: Remove the seal from your C15, insert the dropper (do not remove the air restrictor from the glass stem) and screw the dropper cap closed. The cap will appear to tilt unevenly, but keep screwing it down and the internal air restrictor will snap into place. All done!

Option #2: Remove the seal from your C15, and then pull the air restrictor off of the glass stem of the dropper. Push the pointed end of the air restrictor into the open C15 bottle, applying pressure until it snaps into place.

We also have a handy “How-to” video on our YouTube channel that provides visuals on both of the above options. Once the air restrictor is secure, it will not come loose or fall out—and now your C15 is ready for use!

Can you tell me more about the Resist C15 packaging, i.e. "packaged to minimize light and air exposure"?

A great deal of thought went into the packaging for this product. Because Resist C15 is a water-light liquid, a bottle and dropper-tip applicator were the only way to go for measuring the perfect amount per use while ensuring the product wasn't messy to dispense. To protect the potency of the formula, we selected tinted glass to prevent UV exposure and an internal restrictor to drastically reduce airflow into the bottle when the dropper is removed. In rigorous testing, these packaging safeguards were more than adequate to preserve the effectiveness of the Resist C15 Super Booster. For maximum potency, we advise using C15 Super Booster within three months of opening.
