The unique two-part design delivers a serum that maximizes potency and stays active all the way through its use (unlike many vitamin C serums). Here’s how to mix it up:

Unscrew the tip of the serum activator and squeeze all the contents into the bottle containing the pure vitamin C powder.

Screw the cap on the bottle and shake well until the powder fully dissolves.

Replace the cap with the dropper; it's now ready to use.

Suitable for all skin types. Apply to clean, dry face and neck in the morning and evening. 

Caution: For external use only. Avoid contact with eyes. If irritation persists or allergic reaction
occurs, rinse off immediately, discontinue use, and consult a physician. Keep out of reach of children

We used the purest form of vitamin C in a high concentration because it’s a super potent antioxidant that protects against damaging free radicals and improves the tone, texture, and clarity of skin.

This powerful humectant retains moisture in skin, so it looks and feels hydrated and plump. We included three different molecular sizes of hyaluronic acid; each penetrates different layers within skin so it’s soft, moisturized, and healthy-looking.
