Guanche also notes that anti-aging cleansers tend to be more hype than substance — after all, cleanser isn't typically on long enough to deeply penetrate the skin.

"Anti-aging cleansers don't stay on the skin long enough to be effective," explains Guanch. "Since cleansers stay on your face for just a few seconds and are then rinsed off, it is what's applied afterward and left on the skin that matters most."

A 2017 study published in Clinical, Cosmetic and Investigational Dermatology revealed that micro-needling can be beneficial in helping the skin absorb topical treatments (and agents) such as vitamin C and vitamin A. However, Guanche warns that micro-needling kits should never be tried at home, despite their ready-to-purchase availability online.

"At-home micro needling kits are the most concerning to me, as questions surrounding cleanliness and safety definitely arise," she says. "Additionally, any needling device sold over the counter is likely to be very shallow — so shallow that it is ineffective."

Although a 2015 study published in the Indian Dermatology Online Journal suggested that blue light can be helpful in treating mild-to-moderate cases of acne, board-certified dermatologist Dr. Rhonda Klein, MD, MPH, FAAD, explains that not at-home blue light therapy devices are very different from the one inside your dermatologist's office.

She points out that Neutrogena had to recall their at-home light mask due to customer complaints of vision changes. This makes it important to choose a safe at-home device that won't cause any damage to your eyes.

"A safer alternative is the hand-held LightStim device, which covers a small area of skin at a time and reduces the risk of eye injury," says Klein. "However, your best bet for safety and effectiveness is in-office strength LightStim therapy treatment, which is overseen by a board-certified dermatologist."

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.
