Laser Hair Removal Treatment Guidelines

Pre Treatment Guidelines

  • Laser hair removal is NOT effective on blonde, white, gray, or red hair. If there is a question about the color of hair in the desired treatment area, please consult with a Renew laser treatment provider prior to scheduling treatment.
  • The area to be treated must be clean-shaven at the time of each session. Please shave no more than 24 hours prior to your appointment. Bikini areas should be shaved in the style preferred.
  • Avoid waxing, tweezing, depilatory creams such as Nair, and epilating for at least 4 weeks prior to treatment.
  • Treatment area should be clean and free of creams, lotions, oils, makeup, or deodorant.
  • Patients with abnormal skin lesions or moles in the treatment area must be cleared by a dermatologist prior to treatment.
  • Patients with a history of Herpes simplex virus in the treatment area (cold sores or genital) should be treated with antiviral medication (such as Valtrex) for 2 days prior to treatment and 5 days post. Patients with active infection will not be treated. If you require a prescription for antiviral medication please contact your primary care physician or let your Renew provider know so that arrangements can be made to get you the medication.
  • Accutane or similar products must be avoided for at least 6 months prior to treatment.
  • Physical activity that increases body temperature or blood pressure should be avoided for 2 hours before and after treatment.
  • Laser hair removal treatments must be scheduled a minimum of 4 weeks apart. Your treatment provider will customize your treatment package for safe and effective results. It is important that the full treatment schedule is completed at the intervals recommended by your provider to achieve optimal results.
  • The following should be avoided for at least 7 days prior to treatment:
    • Alpha hydroxy and beta hydroxy products (AHA/BHA), glycolic, lactic and salicylic acids, hydroquinone, retinols/retinoids, Tazorac, Differin.
  • The following should be avoided for at least 2 weeks prior to treatment:
    • Chemical peels to the area being treated, Sunburn or extended sun exposure to area being treated, Sun-sensitive antibiotics such as Doxycycline, Bactrim, Levaquin, and Cipro or herbal supplements such as St. John’s Wort, Botox and dermal filler injections.

What to Expect

Slight discomfort sensations in the form of burning or pinching may be experienced during treatment. Tylenol can be taken 1 hour prior to treatment to reduce discomfort.


Post Treatment Guidelines

  • You may experience slight redness, bumps or swelling in the treated area for up to 72 hours. This is a normal reaction to laser treatment. You can apply cool towels, ice packs, aloe vera or hydrocortisone to relieve symptoms related to heat exposure. If symptoms persist beyond 72 hours, please contact Renew.
  • Seven to 14 days post treatment, hair may begin to “fall out”. Exfoliation is recommended beginning on post treatment day 7 to assist with fallout and prevent in-grown hair.
  • Avoid extended UV exposure for 7 days post treatment. A zinc-based, broad spectrum UVA/UVB SPF 30 or higher sunscreen is essential post laser treatment. We recommend Elta MD which is a medical grade sunscreen available for purchase in-office.
  • Blisters, burns, and skin pigmentation issues are rare post treatment complications with laser hair removal. If you develop any post treatment complications, please contact Renew immediately for treatment recommendations.
