This is my first time using an AHA exfoliant. Will the combination of these two potent products cause a negative reaction?
If you're new to using an AHA or BHA exfoliant, we suggest applying the exfoliant and C15 Super Booster separately; for example using one in the morning and the other at night. As with any skin-care product, you should pay attention to how your skin responds and adjust usage (or products) accordingly.
Is RESIST C15 Super Booster and RESIST Daily Smoothing Treatment with 5% AHA duo recommended for use around the eyes?
Yes, but only up to the orbital bone area (the bony ridge that stops just before the immediate undereye area). Do not apply RESIST Daily Smoothing Treatment to the eyelid or underbrow area.
My skin tends to be sensitive to vitamin C but I still want to use the RESIST C15 Super Booster. Will applying it 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 skin-care product, you should pay attention to how your skin responds and adjust usage (or products) accordingly.
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.
I keep depressing the pump, but no product is coming out.
This product is packaged in an airless pump dispenser which utilizes a vacuum system to dispense and keep the contents fresh. Airless packaging helps to keep air and contaminates out of the product, which enhances the formula's stability and effectiveness.
When using your product for the first time, you may need to “prime” the dispenser. To prime, simply pump the dispenser slowly about 10-15 times. If the dispenser stops working at any time, simply repeat the "priming" step. Do not attempt to dismantle the package.
