ONE THING Niacinamide 10% 40ML


One Thing’s Niacinamide 10% is designed to give skin a hit of pure Vitamin B3. This complexion-perfecting B vitamin works to balance and brighten without irritation so is great if you’re concerned about hyperpigmentation but want a gentle, yet results-driven formula.

It improves your skin’s texture too, working to not only reduce the appearance of pores but to smooth fine lines and wrinkles for a more youthful appearance.

If you’re prone to breakouts and have mature skin, you’ll want to add this essence into your routine for its 2-pronged effect on both common skin concerns.

What’s more, Niacinamide helps to reduce shine and redness and is key for soothing, nurturing and strengthening your skin barrier.


  • 10% Niacinamide to treat hyperpigmentation, pores, redness and texture
  • Butylene glycol, a humectant to prevent water loss


There’s virtually nothing this multi-tasking B vitamin can’t do! We love it for its pore-purifying benefits as well as its anti-ageing and strengthening effect on skin. Like all of the brand’s single ingredient extracts and essences, you can use this formula on its own post-cleanse, as a mist to top-up your skin during the day, layered with other essences or serums or as a dedicated skin pack on problem areas simply soak a cotton pad in the formula, apply it to skin and let it soak in for 10 minutes.

Niacinamide, Butylene glycol, 1,2-Hexanediol, Ethylhexylglycerin

After cleansing, apply this extract in a variety of ways. Use it as a toner and let it absorb into skin; soak cotton pads in it and apply them to your face for a bespoke sheet mask; dispense it into a spray bottle and use it as an on-the-go mist; or add a few drops into your favourite moisturiser to reap its benefits by multi-tasking. Follow with a serum and moisturiser.
