FAQs about TIRTIR Niacinamide 20% Serum (30ml)

Can I use it with other actives?

Yes, but with some care. This serum contains both 20% niacinamide and retinol, so it's already quite active on its own.

Apply after cleansing and toning, before moisturiser.
Avoid layering with other strong actives in the same routine: AHAs, BHAs, PHAs, separate retinoids, strong vitamin C, or peeling solutions.
Always follow with a gentle moisturiser and SPF during the day.
Patch test first and start with a few evenings per week, building up as your skin adjusts.

How does it work on dark spots and uneven skin tone?

The formula approaches pigmentation from a few different angles:

20% Niacinamide helps fade post-acne marks and hyperpigmentation while supporting your skin barrier.
Alpha Arbutin and Glutathione slow down melanin production, so existing spots gradually lighten and new ones are less likely to form.
Retinol speeds up cell turnover, helping discoloured skin shed faster for a clearer, more even complexion.

What's in it and what does each ingredient do?

The serum layers up several brightening and barrier-supporting ingredients:

Niacinamide (20%): evens skin tone, helps with hyperpigmentation, strengthens the barrier and improves texture
Alpha Arbutin: slows melanin production to help fade dark spots, acne marks and freckles
Glutathione: an antioxidant that brightens and helps reduce melanin
Retinol: boosts collagen, smooths fine lines and speeds up cell turnover
Zinc PCA: helps regulate oil and calm irritation
Hyaluronic Acid complex (three forms): hydrates at different skin depths and supports the moisture barrier

What does the texture feel like?

It's lightweight and watery, absorbing quickly without any heavy or sticky feeling on the skin.

What skin concerns does it help with?

It works well for a range of concerns:

Dull, uneven skin tone and lack of radiance
Dark spots, pigmentation, and post-acne marks
Visible pores and uneven texture
Fine lines and early signs of skin ageing
Dehydration and a weakened skin barrier, supported by multiple forms of hyaluronic acid

Suits all skin types, and works particularly well for dull or more mature skin.
