Isntree C-Niacin Toning Ampoule 50ml

A brightening ampoule powered by 70% sea buckthorn fruit extract

This brightening functional ampoule is formulated with 70% sea buckthorn fruit extract. Sea buckthorn is naturally rich in vitamins A, B, C, E, and K, along with amino acids, making it ideal for reviving a dull, uneven complexion. The formula is further boosted with 20,000 ppm of niacinamide to intensively support skin brightening. Its watery texture glides on smoothly and absorbs with a fresh, lightweight finish. Despite being a functional ampoule, it layers beautifully under makeup without any sticky residue.

Dermatologist-tested. Gentle enough for sensitive skin.

Clinically tested with a skin irritation index of 0.05, this formula has been rated hypoallergenic. Even sensitive skin types can confidently begin their vitamin care routine. The natural golden hue comes from the sea buckthorn fruit itself, not artificial colorants. Over time, the color may lighten slightly, but this does not affect the product's efficacy or safety.

A synergy of 4 vitamins and hydration boosters

The brightening vitamin complex is thoughtfully layered.

• 3-O-Ethyl Ascorbic Acid (Vitamin C derivative): A stabilized form that targets uneven skin tone
• Niacinamide (Vitamin B3): A brightening functional ingredient
• Panthenol (Vitamin B5): Soothes and hydrates
• Bioflavonoids (Vitamin P): Revitalizes dull-looking skin

Aloe vera leaf extract, hyaluronic acid, and beta-glucan round out the formula with a surge of moisture. Ideal for those concerned with dark spots and melasma, anyone dealing with a dull, lackluster complexion, or those who want naturally radiant skin without makeup. Always follow with sunscreen after use.

Use after toner, in the essence or serum step

C-Niacin Toning Ampoule is designed to be used after cleansing and toning, during your essence or serum step. Its watery texture absorbs quickly and helps your moisturizer or sunscreen adhere more seamlessly.

Safe for morning and evening use, but always follow with SPF in the AM

Both the vitamin C derivative (3-O-Ethyl Ascorbic Acid) and niacinamide are stable enough for twice-daily use. However, because the formula contains a high concentration of sea buckthorn fruit extract, always apply sunscreen after morning application.

Dispense 2–3 drops into your palm and press in gently

Use the dropper to dispense 2–3 drops into your palm and warm the product slightly with your body heat. Massage gently over your entire face, then press in with your palms until fully absorbed for a fresh, non-sticky finish.

Recommended routine pairings by skin concern

• Dull complexion: Layer with a vitamin C serum to amplify tone-evening results
• Dark spots or post-blemish marks: Follow with an onion extract gel cream to target lingering discoloration
• Dryness-prone skin: The formula contains beta-glucan, hyaluronic acid, and aloe vera leaf extract—seal it all in with a hydrating moisturizer to support lasting moisture

Storage and usage notes

Due to the natural pigments in sea buckthorn fruit extract, the color may lighten over time, but this does not affect product quality. Store in a cool place away from heat and direct sunlight. If redness, itching, or irritation occurs during use, discontinue and consult a dermatologist.
