Skin care is an ever-evolving subject, and it almost seems as though every time we finally get used to the rise of one buzzy trend or ingredient, there's another one that quickly follows in its footsteps to become the next talk of the town. From niacinamide [1] to hyaluronic acid [2] to toner serum hybrids [3], there is no shortage of options to elevate your skin-care routine. While these don't seem to be changing in popularity any time soon, it appears that waterless products and powders are also slowly becoming the next big thing.

In early August, affordable skin-care brand The Ordinary released a 100 percent Niacinamide Powder [4] that highlights the ingredient itself in its truest form. The powder can be mixed with any water-based product, and according to a product description, "allows the user to personalize their usage based on their preference." But does buying a product or ingredient in the form of a powder — as opposed to a serum, cream, or gel — make it better or more effective? According to dermatologist Tess Mauricio [5], MD, it depends.

"Skin-care powders are some of the most popular and scientifically proven ingredients in their concentrated, anhydrous form," she told POPSUGAR. "By removing water, alcohol, and oil from the formulation, the need for some stabilizers and preservatives, which can result in irritation and allergies, is eliminated. Skin-care powders can be more effective depending on the ingredient, since the powdered products usually come very concentrated."

Powder-based products are also more cost-effective, and they're generally made for consumers to be able to customise them to fit specific needs. But when mixing ingredients without the help of an expert, there's always a slight risk.

"The ability to customise and be your own formulator is attractive but can also be challenging," Dr. Mauricio said. "The inherent challenge for the powders is that instead of having scientists, chemists, and medical professionals determine safe concentrations and product combinations that are tested prior to releasing to the general public, the person at home will essentially be experimenting on themselves. Safety issues and the possibility of irritation can occur, especially for those with more sensitive skin."

If you do choose to test out a powder-based product that's meant to be mixed, make sure you follow the manufacturer's directions when doing so, and read up on all the ingredients you shouldn't combine [6]. You should also discontinue use if you start to feel any irritation after applying the product.

The Ordinary 100% Niacinamide Powder

The Ordinary 100% Niacinamide Powder [7] ($6) is as DIY [8] as it gets. It's meant to be mixed into water-based products to help target specific skin issues like enlarged pores and excess oil, though it's up to you to customise how much of the product you actually want to use. Just be careful not to combine it with any of the ingredients the manufacturer doesn't recommend you mixing it with.

Versed Found The Light Powder With Vitamin C

Vitamin C is known to be somewhat of a tricky ingredient because of the way it oxidises and breaks down when it's exposed to the elements.
