So, how exactly does this trend work and is it an effective skincare method for anti-aging? We asked Dr. Elaine F. Kung, MD, of Future Bright Dermatology and Dr. Deanne Mraz Robinson, MD, FAAD, president and co-founder of Modern Dermatology to find out. Keep reading to know more.
What You Need To Know About SluggingAccording to Dr. Kung, “The idea of layering a thick occlusive emollient, containing ingredients like petrolatum, lanolin, shea butter, beeswax, as the last step of a night-time routine is nothing new. This practice has been spotlighted and branded by the catching term ‘slugging’ on TikTok. In fact, purveyors of K-beauty have been pushing this practice of slugging in their 10-step beauty routines for years!”
She adds, “Many people have been unwittingly slugging for years with the trend for vegan or organic skin care. [Several] people have been using toners, serums, or lotions with plant-derived oils and then applying a moisturizing cream thinking those other steps in their skin care routine are not moisturizing enough.”
Dr. Kung explains that by applying products such as Vaseline, Aquaphor, Cerave, or Cetaphil Healing Ointments on your face, you’re helping your skin “reduce transepidermal water loss.”
She says that improving and repairing the skin barrier is most helpful for people who:
- Are suffering with atopic dermatitis / eczemaHave irritable skinHave dry and chapped skinAre living in cold and dry climates
“Because the skin barrier is protected overnight, people wake up with softer and glowing skin. Of course, if the skin is moisturized, it helps soften the appearance of fine lines and wrinkles.”
Dr. Robinson confirms this and notes that “slugging is a practice that helps to seal in whatever actives were applied underneath.” She also mentions, “Applying an occlusive prevents transepidermal water loss, locking hydration and skincare products applied underneath for maximum benefit. Hydrated skin always looks younger and rejuvenated. It is reparative and promotes overall skin healing.”
However, Dr. Kung emphasizes that slugging is not for everyone. “People who have the following should not be slugging because trapping oils in the skin will only worsen their underlying problems.”
- Oily skinAcne-prone skinClogged pores, white heads (milia), blackheadsSeborrheic dermatitis
Dr. Robinson agrees, and clarifies that “the practice can be helpful for aging skin as long as you are not acne-prone.” She warns, “Slugging [on top] of a retinol can cause irritation. Instead you could experiment with slugging [over] a topical antioxidant, peptides, ceramides, and humectants like hyaluronic acid.”
So if you find yourself with any of the conditions previously mentioned, do not layer oils on your face and seal them with petrolatum, shea butter, and beeswax. That’s a big mistake!
