Is laser hair removal safe during pregnancy?

What does the evidence say about laser hair removal during pregnancy?

1. A systematic review of cosmetic procedures during pregnancy and lactation recommends limiting hair removal to waxing, shaving, and topical options rather than permanent procedures. 1
2. Lasers used cosmetically to remove hair carry risks that include pain, infection, bleeding, scarring, and changes in skin color. 2
3. Laser hair removal works by targeting the melanin inside the hair follicle, and reported side effects include redness, swelling around the follicles, crusting, and both lightening and darkening of the skin depending on skin tone. 3
4. Pregnancy raises melanin production, which is what drives melasma and other dark patches, and ACOG advises daily sunscreen and a wide-brimmed hat to keep those changes from deepening. 4
5. The wider literature sets a two-part test for any procedure during pregnancy, safe and necessary, and elective hair removal fails the second half of it. 5

Is laser hair removal safe in each trimester?

• First trimester. Nearly every clinic defers here, and good providers ask about pregnancy at booking. Nothing suggests a single session before you knew has caused harm, but the elective ones get postponed.
• Second trimester. Hormone-driven hair growth changes are in full swing, so results from a session now may not hold. Melasma is also more likely, and laser energy targets pigment.
• Third trimester. Comfort joins the list. Lying still for a long session is harder late in pregnancy, and skin is at its most reactive and most likely to darken afterward.
