Post Treatment

Sunlight

Patients should avoid exposure to sunlight by applying at least SPF 30 and protect the treated area from the sun for at least 2 weeks. Tanning after treatment sessions may enhance melanin regeneration, which may result in hyper-pigmentation.

Shaving

Do not shave the treated area for at least 1 day after treatment.

Beauty & Skincare

Makeup

The face may be sensitive to makeup or makeup removal for the first 24 hours. Exfoliate your skin with a gentle cleanser and wash cloth or loofah. Hair will continue to fall out for up to three weeks following treatment. Avoid any irritating medications or chemicals such as Retin-A, Benzoyl peroxide, glycolic acid or astringents.

Bathing

Due to skin sensitivity avoid washing the treated area with hot water for 24 hours. Avoid saunas and hot baths for 3 days.

Why Would Hair Grow Back?

Laser hair removal provides a permanent reduction of hair growth up to 90% after 6-8 sessions up to 2 years, according to the FDA. This means that you shouldn’t expect to permanently remove every single hair from the targeted area; however, you can expect to remove the vast majority of it. Hence, the FDA’s use of the term “permanent hair reduction” rather than permanent hair removal. For the few cases that hair does grow back, the hair that grows is usually lighter and finer.  

However new hair follicles will produce new hair due to unbalanced hormones caused by:

  • PCOS (Poly Cystic Ovary Syndrome)
  • Pregnancy
  • Menopause

Additional Notes

To avoid skin irritation, consider avoiding excessive exercise for 1 day after treatment.

The treated area may become pink, red, inflamed, or even blistered within 30 minutes and in rare instances, last several hours to several days. Regular application of ice, cooling gels, hydrocortisone or Neosporin is important for relief. Do not wax, pluck, thread or use depilatories for the hair that grows back.

After laser treatment, hair may continue to grow out as if it were never treated. You should see hair begin to fall out within the following 3 weeks. Generally it is best to wait 4-8 weeks between treatments.

There is no advantage to scheduling your visits closer together even if you do not see immediate results. The laser only targets hair in the growth phase. The next growth phase is generally in 4-8 weeks.
