COSMO 10% NIACINAMIDE + ZINC.

COSMO 10% Niacinamide + Zinc Face Serum is a water‑based serum formulated to help acne‑prone, oily or combination skin balance sebum, reduce blemishes, shrink visible pores, and even out skin tone. It combines a potent dose of niacinamide (vitamin B3) with zinc PCA to target multiple skin concerns — from oil and breakouts to dullness or uneven tone.

Key Ingredients & Their Benefits

• Niacinamide (10%) — a versatile, skin‑beneficial derivative of vitamin B3: helps brighten dull skin, even out tone, reduce dark spots or post‑acne marks, improve skin texture, and support the skin barrier. It can also moderate oiliness and blemishes when used consistently.

• Zinc PCA (non‑comedogenic form of zinc) — helps regulate sebum (oil) production, calm irritation/inflammation, and support clearer skin. Zinc is known to help with acne-prone skin and can assist in reducing breakouts and excess shine.

• Hydrating and skin‑conditioning agents (e.g. glycerin or similar humectants) — these help the serum remain lightweight while maintaining hydration, preventing over‑dryness or tightness that can come with oil‑control formulas.

Product Features & Benefits

• Oil & shine control — by regulating sebum production via zinc PCA, the serum helps keep skin looking balanced and matte rather than greasy, which can help reduce acne triggers.

• Reduces blemishes, breakouts, and post‑acne marks — niacinamide helps fade dark spots, even tone, and zinc helps calm inflammation and prevent new breakouts, working together to improve overall clarity.

• Refines pores and smooths texture — many users find pores appear tighter, skin feels smoother, and texture becomes more even over weeks of regular use.

• Lightweight, fast‑absorbing, non‑greasy — suitable for use daily (morning or night), and layers easily under moisturizer or sunscreen without leaving heavy residue — an advantage especially in warm/humid climates.

• Barrier‑supportive and brightening — beyond oil and acne control, the niacinamide supports skin health, improves tone, and can contribute to a more radiant, even complexion over time.

How to Use

1. Start with a clean, dry (or slightly damp) face. Apply 2–3 drops of the serum over face and neck, gently massage or pat until absorbed.

2. Follow with a moisturizer. If applying in the morning, finish with a broad‑spectrum sunscreen.

3. Use daily — either once or twice a day depending on your skin’s tolerance and needs.

4. As with any active treatment, consider patch‑testing before first use, especially if you have sensitive or reactive skin.
