Niacinamide, also known as nicotinamide, functions as a cellular communicator that helps your skin repair and protect itself. This water-soluble vitamin works with your skin's natural substances to improve visible signs of enlarged pores, uneven skin tone, and dullness.

This ingredient exists naturally in many foods you likely consume regularly:

• Meat and fish (especially chicken and tuna),

• Mushrooms,

• Green vegetables,

• Beans and legumes,

• Whole grains.

For skincare purposes, manufacturers typically create synthetic nicotinamide through chemical processes, ensuring stable concentrations in products.

Niacinamide benefits stand out among skincare ingredients for its remarkable versatility and tolerance profile. While many active ingredients address just one concern, this form of vitamin B3 tackles multiple issues simultaneously. Its greatest strength lies in stabilizing the skin barrier—the protective outer layer that keeps moisture in and irritants out.

Unlike harsher ingredients, vitamin B3 suits nearly all skin types—from oily and acne-prone to sensitive and dry.

Most importantly, nicotinamide plays well with virtually all other skincare ingredients, making it an easy addition to any routine.

Both approaches benefit your skin, but in different ways.

Taking food or drinks rich in ascorbic acid:

• supports overall skin health from within,

• reaches all layers of skin through bloodstream,

• helps build collagen throughout the body,

• boosts immune function which supports skin repair.

Applying ascorbic acid on your skin:

• delivers higher concentrations directly to skin cells,

• targets specific concerns like dark spots,

• provides immediate environmental protection,

• shows visible results more quickly.

Niacinamide and vitamin C create a synergistic effect that enhances overall skin appearance more effectively than either ingredient alone.

Niacinamide strengthens the skin barrier and regulates oil production, creating the perfect foundation for vitamin C to penetrate effectively.

While ascorbic acid fights free radicals, niacinamide helps cells repair and rebuild. This combination tackles both prevention and recovery simultaneously.

For hyperpigmentation, these ingredients work through different pathways: vitamin C inhibits melanin production, while vitamin B3 prevents melanin transfer to the skin surface. This dual action fades dark spots more quickly.

Sensitive skin types often find that niacinamide helps buffer potential irritation from vitamin C, making this combination surprisingly well-tolerated.

This pairing also boosts hydration levels more effectively, as nicotinamide improves natural moisturizing factors while vitamin C supports healthy barrier function.

Niacinamide and vitamin C can be used together in a skincare routine, but it's important to layer them correctly, especially when also using active ingredients like glycolic acid and niacinamide to avoid irritation.

For those who find traditional ascorbic acid formulations unstable or irritating, Caudalie's patented Viniferine offers a groundbreaking alternative derived from grapevine sap.

Viniferine is 62 times more effective* at correcting dark spots than vitamin C in its pure form.

Viniferine blocks enzymes responsible for dark spot formation while simultaneously enhancing cell renewal. Its natural origin makes it suitable for even the most sensitive skin.

When paired with niacinamide in Caudalie's Vinoperfect range, Viniferine creates a gentle yet powerful brightening system that delivers visible results without oxidation issues or potential irritation.

Caudalie's Vinoperfect range offers a complete brightening solution that leverages both niacinamide and Viniferine to target dark spots and enhance radiance.

The dark spot serum for radiance delivers concentrated action with two key ingredients.

The star component, Viniferine, Caudalie's patented molecule derived from vine sap, provides dark spot correction 62 times more effective than vitamin C. What's more, olive squalane, extracted from renewable olive oil, moisturises and soothes without leaving a greasy residue.

Apply two to three drops to cleansed skin morning and evening for optimal results.

The eye cream for dark circles targets the delicate orbital region with a specialized formula.

Viniferine works alongside vitamin B3 to diminish dark circles while reducing the appearance of enlarged pores. Caffeine, extracted through green chemistry processes, delivers antioxidant protection while addressing puffiness and further reducing dark circles.

Pat gently around the eye contour after applying serum.

The instant brightening moisturiser with niacinamide provides essential hydration while continuing the brightening action.

This day cream combines Viniferine and vitamin B3 in a light, comfortable formula that creates an ideal base for makeup while protecting against environmental aggressors.

Apply on the face and neck each morning after serum and eye cream for continued brightening throughout the day.

The anti-dark spot night cream works during sleep when skin naturally enters repair mode. This overnight treatment combines Viniferine with papaya enzyme that gently exfoliates dead skin cells, enhancing penetration of active ingredients. Glycolic acid provides additional chemical exfoliation, encouraging cell turnover to reveal brighter, more even-toned skin by morning. Apply to face and neck in the evening after cleansing and serum.
