Key ingredients: niacinamide, zinc PCA

Size: 2 oz

One of the great uses of niacinamide is its ability to keep sebum production at a minimum. Here, it has some help; in addition to niacinamide visibly reducing the appearance of impurities, zinc PCA backs it by controlling oil to prevent future breakouts or congestion. “I love this cult favorite niacinamide serum due to its affordability and its extraordinary ability to both calm inflammation and blemishes. Zinc is anti-inflammatory and helps control sebum products, so combined with a high % of niacinamide, this serum helps to cut down on oiliness, decrease acne, calm redness, and truly smooth out the overall skin texture and complexion over time. I also love that it is super safe to be used by all skin types,” Dr. Lauren Penzi explains.

Dermstore rating: 4.7/5 stars

A Dermstore reviewer said: “I have been purchasing this product for the past five years. During this time I have tried other hyaluronic acid serums to try to save money, but none of them have even come close. I mist my face with a little water and then pat this into my skin. My skin has gotten so soft, and it always feels so nice and hydrated because of this serum. In my late 40s, my skin looks better than it did in my 30s and I attribute a lot of it to this serum. I use it every single day. Highly recommend.”

Unlike many other ingredients, niacinamide actually plays well with others. However, there are a few ingredients you should avoid combining it with:

Vitamin C (L-ascorbic acid): According to Spagnuolo, vitamin C and niacinamide are tricky to combine, as both need to be formulated properly to carry out their functions effectively. “While some studies suggest that niacinamide and vitamin C can be used together effectively, there is a possibility of them canceling each other out when combined at very high concentrations or low pH levels. It’s best to use them separately or in formulations where their compatibility has been ensured,” she says.

Retinoids (such as retinol, tretinoin): Since retinol is already a potent ingredient on its own“Combining niacinamide with certain retinoids may cause flushing or irritation in some individuals. However, many people successfully use both ingredients together without any issues. If youÆre concerned, consider using them at different times of the day or on alternate days.

Acids (such as AHAs, BHAs, and salicylic acid): While niacinamide itself is not acidic, combining it with highly acidic products may cause temporary flushing or irritation in some people. Again, this largely depends on individual skin sensitivity and the specific products being used. It’s generally safe to use niacinamide with mild acids, but be cautious when combining it with stronger ones.
