Although diffused essential oils may fill your space with soothing and calming scents, Klein says that these same oils aren't always suitable for use on the skin.

"As a dermatologist I have seen the adverse impact of essential oils, resulting in dermatitis, skin irritation and flare-ups of rosacea or psoriasis," she warns. "Essential oils must be properly diluted in a carrier oil to be used safely."

Collagen-infused powders and supplements may have had a big moment this year, but much like facial rollers, board-certified dermatologist Dr. Sonia Batra, MD, argues that there isn't much science to back up any product claims.

"Because collagen is the most plentiful protein in the body, ingested collagen typically will find its way to other organs, muscles and bones tendons and won't necessarily help your skin," she explains.

But should you be looking for the extra collagen boost, Batra recommended beefing up your nutrition instead. She notes that eating a nutrient-rich diet containing protein, vitamin C, zinc, and copper can contribute to the creation of collagen.
