Isntree C-Niacin Toning Ampoule 50mL

Isntree C-Niacin Toning Ampoule is a leave-on facial serum focused on dullness, uneven-looking tone and dehydration. Niacinamide, sea buckthorn fruit extract and 3-O-ethyl ascorbic acid form its brightening-focused ingredient story. Unlike the brand’s Hyper Vitamin C 23 Serum, this ampoule uses a vitamin C derivative and is not identified as a 23% pure ascorbic acid treatment.

Its lightweight base includes glycerin and betaine, with aloe, sodium hyaluronate and beta-glucan for moisture support. Panthenol and allantoin round out the conditioning care. Apply it in the serum stage after toner and before cream, patting a few drops into the face or the areas where you want extra tone-focused care.

Vitamin-focused brightening in a water-like ampoule

C-Niacin Toning Ampoule combines tone-focused ingredients with hydration in a light leave-on texture. The formula is designed to absorb comfortably without the richer feel of a cream. Its mix of humectants and botanical ingredients makes moisture part of the same step, rather than treating radiance as a reason to overlook dry-feeling skin.

• Niacinamide and sea buckthorn: These key ingredients support the ampoule’s brightening focus and help care for the appearance of a dull or uneven-looking complexion.
• Vitamin C derivative: 3-O-ethyl ascorbic acid provides a vitamin C derivative within the formula, alongside panthenol and bioflavonoids in its vitamin-focused blend.
• Moisture-supporting trio: Aloe leaf extract, sodium hyaluronate and beta-glucan complement glycerin and betaine, giving the ampoule a clear hydrating component.
• Comforting ingredients: Panthenol, allantoin and dipotassium glycyrrhizate add skin-conditioning support alongside the brightening ingredients and botanical extracts.
• Lightweight dropper format: The water-like, non-sticky texture spreads easily over the face. The 50mL dropper bottle lets you dispense a small amount for the serum stage of your routine.

A brighter look with comfortable hydration

An even-looking complexion often benefits from a routine that also keeps skin moisturized. This ampoule pairs its brightening focus with a lightweight hydrating base, helping skin feel comfortable while you work toward a more radiant appearance. It is a treatment layer before moisturizer, not a cream or an exfoliating peel.

• Radiance for dull-looking skin: Niacinamide and the vitamin-focused blend help improve the appearance of dullness and support a fresher, more luminous-looking complexion.
• More even-looking tone: The formula targets uneven-looking skin tone and the appearance of dark marks, with results that depend on consistent use and individual skin response.
• Moisture without heaviness: Humectants and the aloe, hyaluronic acid and beta-glucan blend add hydration without requiring the richer finish of a cream serum.
• Easy daily layering: The light texture absorbs comfortably before moisturizer, making it straightforward to add tone-focused care to either a simple or a more layered routine.
