Stay Out of the Sun

No surprise, this no-no takes top billing. It really is vital—and for longer than you might think. “There are many different lasers, but for ablative lasers, it is really important to avoid sun exposure for at least two to four weeks after the laser depending on the depth of the laser,” advises Omaha, NE dermatologist Joel Schlessinger, MD. “For the first six months after an invasive laser, it is essential to wear a good sunscreen on a daily basis and, of course, avoid significant sun exposure.”

Besides taking sun protection seriously, Montclair, NJ dermatologist Jeanine Downie, MD stresses to reapply and to avoid exercising in bright sunlight post-laser.

Don’t Tan

It only needs a sentence: “No tanning bed ever—but especially not after a laser,” says Dr. Downie.

Avoid Picking

Another any-time skip: “No picking at your face, no sleeping on your face, no scented products on your face,” advises Dr. Downie.

Skip Some Products

Like with most things, less is more. Dallas dermatologist Elizabeth Bahar Houshmand, MD says that statement is especially true post-laser. “Keep your post-procedure routine simple,” she says. “Stick to soothing and protecting your skin with barrier creams and emollients. Avoid active ingredients like retinol, retinoids, glycolic acid and lactic acid.”

Dr. Joel Schlessinger also recommends the “simple” post-laser life: “Use a good product to moisturize and avoid fragranced products if at all possible while healing,” he says. “We recommend Alastin Skincare Regenerating Skin Nectar With Tri Hex Technology ($236) for a week or two after a procedure such as Halo or Moxi.”

Phoenix dermatologist Dr. Karan Lal praises the Avène Cicalfate+ Restorative Protective Cream ($26) in particular. “It can restore the skin barrier and it can be used on open skin.”

Handle With Care

Omaha, NE dermatologist Daniel Schlessinger, MD offers all his laser-resurfacing patients this sage piece of skin advice: “Think of freshly lasered skin like that of a newborn: fragile, sensitive and prone to infections. Don’t go out in the sun. Don’t go in a swimming pool, hot tub, sauna or steam room. Don’t forget to wash your hands frequently.”

Watch Your Cleanser

In addition to skipping certain ingredients, Dr. Houshmand stresses it’s important to pay particular attention to your cleanser. “Use a gentle, emollient cleanser and avoid scrubs or products with salicylic acid or benzoyl peroxide,” she says.

And if you aren’t sure, ask. “If you are planning to start any new products on your skin, make sure you check first with your dermatologist,” stresses Dr. Daniel Schlessinger. “Products that contain fragrances or certain chemicals can get into the exfoliated skin and lead to a rash called allergic contact dermatitis.”

Bedtime Rules

A dirty pillowcase is never your skin’s friend, but Dr. Lal says that takes on a whole new meaning post-laser. “You do not want to sleep on old sheets after a laser to reduce [the] risk of infection and acne breakouts.”

Pet Smart

Another skip tied to infection: “Do not let your pets lick your face after a laser treatment,” Dr. Lal says.

Breakup With Makeup

Sorry, glam-lovers, but your skin will thank you. “If possible, I advise skipping the makeup to allow your skin to heal properly,” says Dr. Houshmand.

Avoid Heat

Lasers like IPL or BBL do not resurface the skin, but they do heat up the skin, explains Dr. Daniel Schlessinger. “That’s why the heat from any sun exposure can lead to hyperpigmentation. The same goes for heat from excessive physical exertion, saunas, steam rooms or hot tubs.”

Follow Directions

Above all else, follow your provider’s directions. “Follow all of the post-care laser instructions,” advises Dr. Downie. “If you get a breakout or if you’re prone to cold sores, you should tell your doctor and be on medication.”
