To maximize the effectiveness of your serum, it's best to store in the refrigerator or a cool, dark place. Keep the bottle air tight.

How To:


If you’re new to acids or have sensitive skin, start by mixing 2-3 drops in your moisturizer and applying onto your face every night. If you see no signs of irritation after two weeks, apply 1-2 drops directly onto your skin every other night, always following with a hydrating moisturizer. Gradually work your way up to applying the serum every night. This Vitamin C serum is recommended as a night treatment. If used before sun exposure, make sure to apply sunscreen.

Triple C Lightning Liquid is a highly concentrated serum with pure Vitamin C, so your skin may feel sensitive or tingly upon application.
