Short-term side effects can take place with overuse or application of high concentrations, particularly in people with sensitive skin or prone to allergic reactions.
Symptoms can include redness, itching or burning. If you feel this may apply to you, please consult a dermatologist. (4)
Oral supplements may be preferable for people with a history of skin allergies.
Niacinamide serums can also be diluted with other products, such as moisturiser, to avoid applying high concentrations directly to the skin, though most formulations will be fairly dilute already.
What is it used for?
Niacinamide can be used daily as part of your skincare routine. It supports new collagen synthesis and maintenance of important skin factors that naturally deplete with age(2).
Additionally, studies have shown that it can prevent UV damage and hyperpigmentation, as well as regulate oil levels and reduce acne. (3)

Alice’s Take
“Niacinamide is central to my personal skin routine - I mix it a drop of serum in with my moisturiser and use after cleansing my skin. I find it makes my skin appear smoother and brighter, and reduces spots.”
