Brighten up your overall complexion and acne scars in a flash with Triple C Lightning Liquid. With 20.5% pure Vitamin C (ascorbic acid), this powerful serum brings back radiance, promotes healthy skin, and treats and prevents pigmentation. It’s also infused with 72% black chokeberry, an ingredient that works to stabilize the Vitamin C and ensure that your skin is smooth and hydrated.

The Charlotte Cho x COSRX Promise:

In order for a pure Vitamin C serum to be effective, it must be fresh. That's why we're making all Triple C Lightning Liquids in small batches and air shipping them directly from Korea to ensure that the serums are fresh and high quality.

1 oz / 30 ml

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.
