These products work by lifting dead skin cells and debris from the outermost layer of your skin through the act of peeling the dried mask off. Compare that to chemical exfoliants, which use alpha- or beta-hydroxy acids to loosen the bonds between skin cells (Though it’s worth noting that many peel-off face masks also contain supporting exfoliating acids.) Traditional physical exfoliants like scrubs, on the other hand, use small, textured particles to remove dead skin cells and debris, board-certified dermatologist Dr. Ryan Turner, M.D. explain

In terms of what causes sebaceous filaments, Dr. Turner says that they are made from oil production and dead skin cells. Again, he emphasizes that this is totally normal. “Sebaceous filaments can be a natural process in the skin to move sebum to the surface of the skin for moisturization,” he says. Dr. Turner says that blackheads, on the other hand, pop up when there is excess oil, which clogs pores.

Board-certified dermatologist Dr. Ryan Turner, M.D. says melanated skin can get sunburned and experience the negative effects associated with prolonged UVB exposure, like skin cancer. “While melanated skin offers some natural protection, sun protection is advised for skin of all colors,” Turner says.

Harvard-trained dermatologist Dr. Ryan Turner, MD, adds that the fluid in the blisters may be white or clear and the adjacent skin may be red, swollen, and painful to the touch.

Dark knees can show up on anyone, but they’re most common in people with darker skin, explains board-certified dermatologist Dr. Ryan Turner, M.D. The New York City-based doctor says, “When a person’s natural skin pigment is darker, the chances of having dark knees increases, but darker knees may appear in people of all skin tones and types.”

“Kits offer a great opportunity to try out products before splurging on full-sized counterparts,” says Dr. Ryan Turner, a dermatologist in New York City. “They are great for men looking to start a skin care regimen or looking to shift their regimen to focus on specific concerns.”

For the most common ways that stress can impact your skin and hair, we spoke with Dr. Ryan Turner of Turner Dermatology in NYC. Before diving into that list, though, it’s important to define the stress itself. Because “stress” isn’t simply referring to a bad day at work, a fight with a partner or friend, or missing your commuter train. Stress is all encompassing. Even being poorly rested registers as stress on the body.

Because bentonite clay pulls off a brilliant vanishing act on grease and other nasties, it's a good option for folks with oily or acne-prone skin. "bentonite clay helps to control sebum production, creates a matte finish, and minimizes the look of prominent pores," explains New York City-based board-certified dermatologist Ryan Turner, MD. Its antioxidant minerals (known as phyllosilicates) and anti-inflammatory properties calm angry breakouts, Dr. Turner adds. Also cool: it temporarily tightens pores, leaving skin feeling like it's been shrink-wrapped.

According to Dr. Ryan Turner, a dermatologist practicing in New York, "beard balm is thicker and primarily used for styling and locking in moisture to just the beard. Beard butter, on the other hand, has a more flexible hold, and its uses are primarily for moisturizing the beard and skin." Turner explains that what separates beard butter from other beard products is the dual role it plays. "Beard butter acts as a moisturizer for the beard, as well as the skin underneath. It can be used both as a moisturizer and as a lightweight styler," he says.

The development of horizontal lines across the neck can be concerning for many, but Ryan Turner, MD, a board-certified dermatologist in NYC, recommends this next-generation skin tightener that contains a potent combination of antioxidants. It also has squalane for skin barrier repair and proprietary peptides to improve collagen and elastin. While Turner says it is a bit more pricey, it remains one of his go-to products for patients.
