Overview

Two ingredients that instantly come to mind for glowing skin are Niacinamide and

Vitamin C. Both are popular for their ability to protect, repair, and enhance radiance.

Niacinamide serum helps with concerns like uneven tone and sensitivity, while Vitamin C serum is well known for brightening dull skin. Each works powerfully on its own, but together, they are an infallible duo for maintaining healthy, balanced skin. Understanding their unique benefits will help you decide which serum is best for your needs.

What is Niacinamide?

Niacinamide is a form of water-soluble Vitamin B and Vitamin B3, a skincare all-rounder. This compound works at the cellular level to give you a strong skin barrier, thus preventing inflammation. It also controls oil production, making it an ideal choice for acne-prone skin. However, modern skincare involves using Niacinamide for various other skin concerns as well.

Key Benefits of Niacinamide

What is Vitamin C?

Vitamin C is best known for its brightening properties, ensuring even out skin tone and giving your complexion a natural glow. Rich in antioxidants, it is naturally found in citrus fruits such as oranges and kiwis. It also protects your skin by neutralising free radicals in the surrounding environment.

Topical application of Vitamin C simulates Collagen production. This helps in reducing the early signs of ageing visible in the form of fine lines and wrinkles.

Key Benefits of Vitamin C

Brightens the Complexion: It restores your natural glow with consistent use, as it fades dark spots. It also prevents hyperpigmentation and dullness caused by free radicals.
Collagen Production: This action minimises visible fine lines and sagging of skin. You will also notice your skin is firmer with improved elasticity.
Protection Against Free Radicals: Neutralises the impact of aggressors released by UV exposure, pollution, and other environmental factors due to its antioxidant properties.
Reduces Hyperpigmentation: A Vitamin C Serum targets stubborn pigmentation issues, including sunspots, age spots, and post-acne marks. It works by inhibiting excess melanin production, helping to gradually even out skin tone.
Enhances Skin Radiance: You can feel your skin visibly glowing as it revitalises your tired and dull skin.

Niacinamide vs Vitamin C: Key Differences

The following differences between Niacinamide and Vitamin C will help you decide which one to use.

1. Skin Repair Mechanisms

Use Niacinamide to protect your skin barrier, support skin repair, and reduce inflammation.

Use Vitamin C to increase Collagen production, brighten your skin, and get antioxidant protection.

2. Targeted Skin Concerns

Niacinamide soothes irritation, reduces redness, and controls oil to prevent breakouts.

Vitamin C fades pigmentation, brightens dull skin, and improves elasticity.

3. Effectiveness in Different Skin Types

People with oily, acne-prone skin and sensitive skin can use Niacinamide.

Vitamin C is mostly suitable for dry and dull skin with uneven tones.

4. Usage and Compatibility

Niacinamide is gentle and easy to layer with other actives.

Vitamin C works best in the morning for antioxidant protection. Avoid layering it with potent actives like Retinol, AHAs, and BHAs in the same routine.

Which Ingredient is Right for You?

For Brighter, Radiant Skin: If your primary concern is dull skin and you want to achieve glowing skin, Vitamin C can help you with it. It brightens dull skin, fades pigmentation, and gives you a youthful appearance.
For Sensitive, Acne-Prone, or Irritated Skin: If you want to prevent breakouts, redness, or irritation, Niacinamide is ideal. It reduces inflammation, protects the skin barrier, and regulates greasiness, thereby improving the overall texture.

How to Incorporate Them into Your Routine:

Niacinamide: Wash your face and then apply Foxtale’s 12% Niacinamide Clarifying Serum followed by a moisturiser. You can use it in the morning and evening routine to ensure even-toned, bright skin daily.
Vitamin C: Use Foxtale’s Vitamin C Serum in the morning after you cleanse your face. Protect your skin from UV damage by using a broad-spectrum sunscreen. It will also prevent sunspots from appearing on your skin.
Using Both Together: If you are new to using Niacinamide and Vitamin C, it is best to start slowly. Use them alternately over several days at different times of the day and watch out for any skin reactions. They can be combined in a routine if your skin tolerates them well.

Conclusion

Niacinamide and Vitamin C can both transform for your skin, but the choice depends on your skin type, concerns, and the result you want. The properties of Niacinamide improve the protective layer, while Vitamin C is best for Collagen-boosting properties. You can use these serums daily to maintain healthy and radiant skin.
