Linda Pietk is sitting calmly in the sleek offices of Union Square Laser Dermatology having her face poked.

“It felt like needle pricks,” says Pietk, a 50-year-old stay-at-home mom from Long Island, who was getting a “microneedling” treatment to reduce wrinkles.

“It wasn’t painful, just slightly uncomfortable,” says Pietk. “Afterward, my face felt warm, was slightly red and a bit swollen. It appeared as if I had sunburn.”

The latest hot beauty trend may sound like a sadistic medical procedure — microneedling basically does to your face what an aerator does to a lawn — but that hasn’t stopped celebrities such as Gwyneth Paltrow and Jennifer Aniston from signing up for it.

The anti-aging treatment is being heralded as a less invasive alternative to Botox, fillers and lasers, which can cause flare-ups of melasma and rosacea, as well as hyperpigmentation.
