What is Niacinamide?

This superstar ingredient, also known as nicotinamide or vitamin B3, is an essential nutrient that your body can’t produce on its own. The good news? You can easily incorporate it into your skincare routine. Niacinamide boasts a long list of benefits, tackling acne, calming inflammation, and even fading dark spots and dealing with hyperpigmentation.

Unlike some other actives, niacinamide is water-soluble and plays well with others. Plus, it’s stable in heat and light, making it a great choice for both your daytime and night time skincare regimen.

What can Niacinamide do for your skin?

Reduces enlarged pores – Niacinamide tackles two key culprits behind enlarged pores: excess sebum and reduced elasticity.1 It controls sebum production, preventing pores from stretching out. Plus, it encourages the purging of excess oil and dirt to the skin’s surface, allowing you to cleanse them away. The result? Tightened pores for a smoother, more refined complexion.

Antioxidant – niacinamide acts as an antioxidant shield, neutralising free radicals that can contribute to premature ageing. This translates to smoother, younger-looking skin for longer.

Anti-ageing – not only a potent antioxidant, niacinamide also helps your skin retain moisture by combating transepidermal water loss and strengthens your skin barrier.2 These combined benefits can even minimise the appearance of fine lines and wrinkles, leaving you with a youthful, healthy complexion.

Acne treatment – niacinamide tackles acne from multiple angles. Its ability to control sebum production helps prevent clogged pores, a major trigger for breakouts. Plus, niacinamide’s antimicrobial and anti-inflammatory properties work together to reduce existing blemishes and soothe irritation.3 With continued use, you’ll see fewer lesions and calmer, clearer skin.

Brightening – research suggests that at 5% concentration, niacinamide can help fade dark spots and hyperpigmentation.1 It works by disrupting the process of melanin production and transfer in the skin, ultimately leading to a reduction in the appearance of those unwanted dark spots.

Can you use Niacinamide when you’re pregnant?

Topical niacinamide is generally considered safe during pregnancy, offering a helping hand with common concerns like melasma, acne, and increased sensitivity. Although, it is best to avoid high concentrations (greater than 5%) when pregnant or breastfeeding. Remember, for personalised guidance on using niacinamide during pregnancy or breastfeeding, consult your healthcare professional. They’ll be happy to advise based on your specific needs.

How do you use Niacinamide?

This superstar ingredient isn’t just a fad – it’s a powerhouse packed into serums, creams, masks, and targeted treatments. Even at low concentrations, niacinamide can visibly improve your skin’s texture. For tackling dark spots and brightening, higher concentrations (5-10%) are often recommended. While generally safe, a patch test is crucial before using any new product with niacinamide, especially at higher concentrations. To optimise results, apply niacinamide after cleansing and toning.

Niacinamide plays well with others. It teams up beautifully with ingredients like retinol, BHAs, hyaluronic acid, green tea, centella asiatica extract, and vitamin E, for a well-rounded skincare routine.
