This MaryenB VNC15 Vitamin C 15% Facial Serum is made for people whose skin looks dull, tired and uneven, and who want a focused daily serum to bring back a fresher, more radiant look. If you notice that your complexion lacks glow, early fine lines are starting to show and dark spots or post‑blemish marks linger longer than you would like, this vitamin C facial serum is designed to slot into your morning routine with ease. It is a good choice for those who want to support brightness, elasticity and more even‑looking tone without adding too many complicated steps.

What – Vitamin C 15% Facial Serum With Niacinamide and Arbutin

VNC15 is a vitamin C 15% facial serum that combines pure ascorbic acid with niacinamide and arbutin to support a brighter, more even‑looking complexion and improved skin elasticity. This serum focuses on visible dullness, early fine lines and uneven tone, including dark spots and marks left behind by past blemishes or sun exposure. The formula is designed to deliver effective antioxidant and tone‑care benefits while remaining suitable for regular use in a simple routine.

How – How This Serum Supports Radiance, Tone and Elasticity

At the core of this serum, 15% ascorbic acid (vitamin C) provides powerful antioxidant support to help protect the skin from the look of environmental stress, while also helping to improve the appearance of overall brightness and clarity. Niacinamide at 1% supports the skin barrier, helps refine the look of pores and contributes to a more even‑looking tone and smoother texture. Arbutin at 1% is included to help reduce the appearance of dark spots and post‑blemish marks so that, with consistent use, the complexion can look more uniform and luminous. Supporting ingredients such as Centella asiatica, green tea, Houttuynia cordata, oat extracts and sodium hyaluronate help keep the skin feeling calm and hydrated while you work on tone and radiance.

Hero ingredients – Brightening‑Care and Antioxidant Blend

The hero ingredients in MaryenB VNC15 are chosen to create a focused brightening‑care and antioxidant serum.

• 15% ascorbic acid (vitamin C) to help improve the look of dullness, uneven tone and early signs of aging while supporting a more radiant‑looking complexion.

• 1% niacinamide to support the skin barrier, refine texture and help even out the appearance of skin tone.

• 1% arbutin to help reduce the appearance of localized dark spots and visible discoloration.

These actives are supported by soothing plant extracts (Centella, green tea, Houttuynia, oat, sesame) and hydrating agents like sodium hyaluronate and butylene glycol for a comfortable, hydrating finish that layers well under moisturizer and sunscreen.

Texture & routine – Lightweight Morning Serum for Daily Glow

The texture of this vitamin C 15% serum is fluid and fast‑absorbing, leaving a lightweight, non‑greasy finish that works well under makeup and daily sunscreen. In the morning, after cleansing and using a gentle toner, apply a small amount of MaryenB VNC15 serum over the face, avoiding the immediate eye area, then follow with a hydrating moisturizer and a broad‑spectrum sunscreen. With regular use, this vitamin C facial serum is designed to help your skin look more awake, more even in tone and visibly smoother, making it a strong anchor step in your daily routine.

Who should avoid – When to Introduce Vitamin C Carefully

Because VNC15 uses a high concentration of ascorbic acid, very sensitive or highly reactive skin may need to introduce it more carefully. If you have a history of stinging or redness from strong vitamin C products, or your skin barrier is already irritated, start with a patch test and use the serum only a few times per week at first. People using multiple acidic products (like strong exfoliating acids) should simplify their routine and avoid layering too many actives at once, watching closely for signs of strong burning, unusual redness or persistent discomfort and reducing frequency or stopping use if these occur.
