One Days You Pro Vita C Brightening Ampoule Serum 30ml

A brightening ampoule that delivers vitamin-powered radiance with a rich, cushiony texture

This dual-functional ampoule serum brings luminous clarity to dull, lackluster skin. Formulated with niacinamide, a brightening functional ingredient, and adenosine for wrinkle improvement, it helps even out skin tone while supporting elasticity. The rich, cushiony texture adheres seamlessly to skin and absorbs without any sticky residue. You'll notice a dewy, hydrated glow from the moment you apply it.

Gentle formula with a 0.00 skin irritation index

Human application testing confirmed a skin irritation index of 0.00, earning it a non-irritating rating. This gentle formula is suitable for daily use, even on sensitive skin. Calamondin orange fruit extract delivers vitamin C to help care for a dull complexion, while propolis extract forms a moisture veil that refines skin texture.

For those seeking clear, radiant skin

Ideal if your skin feels dull and lacks vitality, if you struggle to achieve a clear, luminous complexion, or if dryness and rough texture are your main concerns.

Enriched with sodium hyaluronate for hydration, ceramide NP for barrier support, and beta-glucan for soothing, it delivers brightening and moisture care in one step. After toner, dispense an appropriate amount and smooth over the entire face, then gently pat to aid absorption.

Use after toner, before moisturizer

An ampoule serum is designed to be applied right after you've prepped your skin with toner. After cleansing, smooth on your toner or swipe a toner pad across your face, then follow with this ampoule serum and seal it all in with your moisturizer. If you're layering with an essence or another serum, apply them in order from lightest to richest texture.

Morning and evening use

This dual-function formula targets both brightening and wrinkle improvement, making it ideal for both your morning and evening routines. In the morning, it creates a radiant, tone-evening base under makeup. At night, it delivers brightening care to skin that's been exposed to daily stressors.

Dispense a small amount and press gently into skin

Use the dropper to dispense 1 to 2 drops onto the back of your hand, then smooth evenly across your entire face. The formula has a rich, bouncy texture that absorbs beautifully when you gently press it in with your palms. For areas where dullness is more noticeable, feel free to apply a second layer.

Routine pairings by skin concern

• If dullness is your main concern: Swipe a vitamin C toner pad across your skin first, then follow with this ampoule to amplify the brightening effect.
• If your skin feels dry and lackluster: After the ampoule, lock in moisture with a cream containing ceramides or hyaluronic acid.
• If you're targeting both dark spots and fine lines: Use this ampoule consistently in your evening routine, and be diligent about applying sunscreen every morning to protect against UV damage.

Storage and precautions

This formula contains vitamin C derivatives, so store it in a cool place away from direct sunlight. For best results, use within 6 months of opening. Avoid the eye area during application. If you experience redness, itching, or any irritation, discontinue use and consult a dermatologist.
