TIRTIR Niacinamide 20% Serum (30ml)

TIRTIR Niacinamide 20% Serum (30ml)

Oil, pores, dark spots: one serum, maximum strength.

Niacinamide is one of the most popular ingredients in skincare, and here you get 20% of it. That’s twice the strength of most niacinamide serums. TIRTIR pairs it with Alpha Arbutin and Glutathione for brightening, Zinc PCA for oil control and Retinol for smoother, firmer skin. The result is a single serum for oily, uneven, spot-prone skin.

It has a light, watery texture that absorbs in seconds with no stickiness, which is ideal for humid Nigerian weather.

Why you’ll love it

• Fades dark spots and acne marks: Niacinamide and Alpha Arbutin work together on hyperpigmentation.
• Controls oil: Zinc PCA and Niacinamide keep shine in check all day.
• Refines pores: skin looks smoother and tighter.
• Evens tone and brightens: Glutathione adds antioxidant radiance.
• Smooths fine lines: Retinol supports firmer, more youthful-looking skin.
• Hydrates: three types of Hyaluronic Acid stop skin feeling dry.

Key ingredients

• Niacinamide 20%: brightens, controls oil, refines pores and strengthens the barrier
• Alpha Arbutin: targets dark spots
• Glutathione: antioxidant brightening
• Zinc PCA: balances oil and soothes
• Retinol: smooths texture and fine lines
• Hyaluronic Acid (3 types): multi-depth hydration

How to use
Use it at night after cleansing and toning. Apply 2–3 drops to your face and pat gently until absorbed, then follow with moisturiser. Start 2–3 nights a week and build up as your skin adjusts. Wear SPF 30+ every morning.

Good to know

• Patch test first. At 20% niacinamide plus retinol, mild warmth or tingling can happen at first.
• Don’t layer it with vitamin C, AHA/BHA acids or other retinol products in the same routine. For example, use the TIRTIR Vitamin C 24% in the morning and this serum at night.
• Not recommended during pregnancy or breastfeeding, because it contains retinol.

Best for: oily, combination and breakout-prone skin, plus dark spots, acne marks, large pores, uneven tone and dullness.
