Niacinamide is one of the most Googled skincare ingredients - here's why.
that can be left on the skin for maximum absorption, unlike a cleanser that is immediately washed off.
“Niacinamide can be found in a varying range of concentrations in skincare and is usually well-tolerated causing minimal skin irritation," says Dr Mahto. "Ideally look for products that contain at least 5% niacinamide for the best results and ensure that it features highly on the ingredients’ list of a product ,” she adds.
Dr Sturm also believes 5% is the ideal concentration for niacinamide. “Too high a concentration of topical vitamin B3 can have a negative effect and lead to irritation, sensitivity and redness,” she says.The beauty of niacinamide is that it plays nicely with most ingredients and is particularly useful for offsetting the dryness and irritation that comes with gnarlier ingredients such as retinol.
A key reason for doubling down with this combo is that, while both ingredients fall under the umbrella term ‘brightening’, they have different mechanisms for achieving a more even skin tone. Vitamin C inhibits the production of tyrosinase, an enzyme that is responsible for excess melanin, while niacinamide is thought to prevent the transfer of this pigment within cells.
That said, pairing retinol with niacinamide makes the former easier to tolerate as niacinamide will improve moisture in the skin and temper irritation.Depending on the severity of your skin concern, you should begin seeing results from your niacinamide serum after two to four weeks, with results improving over time.
