2019 saw us through many amazing skin care breakthroughs, from the rise of clean beauty products, to the mass CBD skin care takeover — and we can't say that we weren't impressed.

However, it's safe to say that 2019 also had its fair share of overhyped skin care trends, too: In fact, some experts suggest that certain popular social media-friendly trends aren't exactly the beauty superstars we thought they were.

So, to say goodbye to those fads once and for all, we tapped four board-certified dermatologists to share eight of the most overrated skin care trends they are hoping to leave safely back in 2019. From facial rollers to bee sting facials (yes, really!), read on below to see what skin care habits you should probably ditch in the new year.

Crystal facial rollers may feel soothing (especially when chilled!), but board-certified dermatologist Dr. Anna Karp, MD, suggests that there isn't much science to support the anti-aging claims associated with these products.

"Whether they are made of jade or rose quartz, I think facial rollers are very overrated," says Karp. "These rollers need scientific peer-reviewed studies in order to be deemed credible."

Anti-aging facial yoga poses probably aren't the anti-aging miracle worker you thought they were, according to board-certified dermatologist Dr. Anna Guanche, MD: She explains that these same stretches can actually lead to more wrinkles.

"We have learned that neuromodulators (Botox) work by keeping you from contracting muscles of facial expression and wrinkling up the overlying skin," explains Guanche. "The last thing you would want to do is intentionally contract the muscles of the face and neck, and therefore, accelerate wrinkle formation."

Guanche says that some studies have shown that bee stings are capable of reducing inflammation in the body. However, it can also cause a severe reaction in some patients, she adds, making it an extreme beauty trend to ditch in 2020.

"We all know that many people are allergic to bee stings," she said. "With this in mind, I would avoid this facial until we can be sure that the risks (anaphylactic reactions to bee stings are deadly) don't outweigh the benefits."

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."
