Since the skin has its own bacteria that is essential for maintaining skin health, cosmetic chemist Ron Robinson says we will be seeing more skin care products that contain probiotics (good bacteria) that can help address a variety of different skin concerns.

Unwanted breakouts is an issue probiotics can alleviate. First Aid Beauty Skin Rescue Acne Clearing Charcoal Cleanser With Probiotics, $24, uses probiotics, charcoal and salicylic acid to keep those troublesome pimples at bay.

Although cannabis-based products have been gaining traction for quite some time now, Robinson says the CBD beauty trend will continue to trend this fall, especially since mainstream brands like Milk Makeup are incorporating the ingredient in their product lines. And it's definitely for good reason: CBD may reduce signs of aging and provides soothing and anti-inflammatory benefits to the skin, he says.

To add CBD to your beauty regimen, be sure to pick up Milk Makeup Kush High Volume Mascara, $24, which uses conditioning cannabis oil to thicken up lashes without any unwanted breakage.

"Soy is particularly useful in improving the appearance of dark spots in a gentle, non-irritating way," says Joshua Zeichner, director of cosmetic and clinical research at Mount Sinai Hospital. Zeichner says that soy-based products are a great way to help prepare damaged skin after summer for fall, making it something to invest in if those sunspots are becoming too much to handle.

To successfully brighten up any sun damage you may have developed over the summer, he recommends using Aveeno Positively Radiant Intensive Night Cream, $14.99, which contains total soy complex and vitamin B3 to leave the skin feeling smooth and looking radiant.

"Brands are continuing to launch more products that only contain one hero ingredient," Robinson says. These one-ingredient formulas can be used on their own or the consumer can customize to it to their own needs by blending with other formulas.

The Drunk Elephant Virgin Marula Luxury Facial Oil, $72, is a great example of a stellar one-ingredient skin care product, as it only uses pure cold-pressed marula oil to keep skin balanced and hydrated.
