What is Niacinamide?
Niacinamide is the active form of vitamin B3. It is highlighted for its versatility, good tolerance, and suitability for all skin types, including sensitive ones.
Key Benefits of Niacinamide:
- Reduces Acne and Rosacea: Possesses seborregulating and anti-inflammatory properties.
- Improves Skin Barrier Function: Reduces transepidermal water loss and increases the production of lipids and proteins in the epidermis.
- Minimizes Wrinkles: Boosts the production of collagen and elastin.
- Depigmenting Action: Helps reduce hyperpigmentation, unifies skin tone, and prevents a yellowish complexion through its anti-glycation function (its action is enhanced with tranexamic acid).
- Potent Antioxidant: Protects cells from oxidative stress, particularly in skin exposed to daily exposome factors (pollution, UV radiation, tobacco).
- Regulates Sebum & Matifies: Controls oil production, reduces shine, and visually minimizes pores, especially in oily skin.
- Calms Irritation: Alleviates irritations and reduces redness in sensitive skin.
- Improves Hydration: Strengthens the natural barrier and enhances water retention in dry skin.
- Boosts Skin Renewal: Helps the skin function with more resources, leading to improved radiance and firmness.
Who is Niacinamide Suitable For?
Niacinamide is considered an «all-rounder» ingredient, suitable for all skin types, including:
- Oily skin: Regulates sebum, matifies, minimizes pores.
- Sensitive skin: Calms, soothes irritations, reduces redness.
- Dry skin: Strengthens the barrier, improves water retention.
- Skin with dark spots: Acts on hyperpigmentation, unifies tone.
- Mature skin: Provides a powerful antioxidant action.
What Does Niacinamide Combine Best With?
- NAD+: This coenzyme naturally present in the body helps optimize the utilization of niacinamide, preserving the skin barrier, repairing DNA, and protecting cells from stress.
- Retinol: Niacinamide is an excellent ally for retinol. It helps reinforce the skin barrier and provides a calming effect, counteracting retinol’s potential irritation. This combination allows for more tolerable skin renewal.
- Vitamin C: Both are antioxidants that enhance skin luminosity and reduce dark spots. Niacinamide adds calming and anti-inflammatory benefits, while Vitamin C primarily promotes collagen and elastin production.
