The Popular 10% Niacinamide and Its Supporting Partner

The Popular 10% Niacinamide and Its Supporting Partner

Niacinamide is considered the superstar of skincare, due to its multi-functional benefits which are well celebrated by the community. As discussed in our previous post, Niacinamide has been proven to reduce acne breakouts, improve pigmentation, control oiliness, and alleviate wrinkles and other signs of ageing with concentrations between 2% and 5%.

Will it be okay to use 10% Niacinamide?

Various research had proven that Niacinamide does an amazing job at low concentrations. However, we only see more than 10% Niacinamide products from different brands in the market these days, not less. To date, no research shows that 10% strength outperforms lower concentrations when it comes to Niacinamide skincare.

Putting the issue aside, we decided to look at the review section for popular 10% Niacinamide serums, and surprisingly, positive reviews outweigh the negatives. The majority seem to be enjoying the results from 10% of Niacinamide products. But what about skin irritation?

10% Niacinamide & Irritation

Here's an interesting finding from the 31-page Final Report of the Safety Assessment of Niacinamide and Niacin by the American College of Toxicology (2005).

In several Human Repeat Insult Patch Tests (HRIPT), subjects were asked to use a moisturizer containing 0%, 2%, 10% and 20% Niacinamide, 3 times per week, for 3 weeks. The formulations were sealed neat to the skin under semi-occlusive and occlusive patch conditions. Following the removal of the patch, the skin was graded for signs of irritation. The studies concluded that Niacinamide at levels up to 20%, does not induce significant skin irritation.

However, the reliability and validity of these studies may be questionable as they were generated by Procter & Gamble, the multinational giant that owns Niacinamide-loving brands like Olay & SK-II. Then again, all countries consider Niacinamide a safe cosmetic ingredient as it has no restricted concentration in any country thus far - it's perfectly legal to sell it at 20% or much higher.

The Role of Supporting Ingredients

Not all people experience irritation from 10% Niacinamide skincare, or else it wouldn't be the most popular percentage at present. Most of these 10% Niacinamide products are not created equally. It all comes down to formulary excellence which means; the use of other supporting ingredients and technologies in producing the best Niacinamide products.

For example, a 10% Niacinamide serum with low-grade Niacinamide dissolved in a high concentration of denatured alcohol, loaded with fragrance and colourant, will certainly be more irritating than a 10% Niacinamide serum formulated with soothing ingredients.
