What is permanent hair removal

Permanent hair removal is a procedure that uses laser or IPL energy to destroy the hair follicle.

The goals are:

  • significant reduction in hair growth
  • slowing down its regeneration
  • achieving smooth skin

The term "permanent" means long-term reduction, not complete permanent disappearance.

How it works

The laser acts on the pigment (melanin) in the hair shaft:

  • energy is absorbed by the hair shaft
  • it is transmitted to the root
  • destroys the follicle

It works best on hair in the active growth phase.

Areas that can be treated

Permanent hair removal can be performed on:

  • face (mustache, chin)
  • underarms
  • groin area
  • legs
  • arms
  • back

How the procedure goes

The procedure is quick and varies depending on the area:

  • 10–15 minutes (small areas)
  • up to 60 minutes (large areas)

Steps:

  1. Skin cleansing
  2. Covering moles in the area to be treated
  3. Adjusting laser parameters
  4. Applying the treatment
  5. Applying soothing gel

How many sessions are needed

For optimal results:

  • 6–8 sessions (on average)
  • at intervals of 4–8 weeks

Multiple sessions are necessary because not all hairs are in the same growth phase.

Instructions before hair removal

For maximum effectiveness:

2 weeks before:

  • avoid sun exposure
  • avoid tanning

24–48 hours before:

  • shave the area (DO NOT wax)

On the day of the procedure:

  • skin must be clean
  • without creams or deodorant

Instructions after permanent hair removal

To protect your skin:

In the first few days:

  • avoid sun
  • apply soothing cream
  • use SPF 50

In the first 24–48 hours:

  • avoid intense exercise
  • avoid sauna and hot baths

Normal reactions

May temporarily appear:

  • redness
  • mild swelling
  • sensation of heat

These usually disappear within a few hours or days.

Who is NOT a suitable candidate

The procedure is not recommended:

  • on tanned skin
  • during pregnancy (relative)
  • in infections or skin lesions
  • in certain dermatological conditions

Benefits of permanent hair removal

  • significant reduction in hair
  • no ingrown hairs
  • smoother skin
  • long-term time savings

Disadvantages

  • requires multiple sessions
  • lower effectiveness on very light hair
  • requires periodic maintenance

A single injection for cholesterol — from dreams to first human results

A Phase 1 trial published in the New England Journal of Medicine (November 2025) brings remarkable results: a single infusion of CTX310, a CRISPR-Cas9 therapy developed by Cleveland Clinic and CRISPR Therapeutics, reduced LDL cholesterol by up to 49% and triglycerides by up to 55% in patients with refractory dyslipidemia — without serious adverse events. The mechanism is unique: instead of blocking a protein or interfering with its mRNA, CTX310 permanently edits the ANGPTL3 gene in hepatic cells, mimicking a natural mutation associated with reduced cardiovascular risk throughout life. The therapy is currently in Phase 1b clinical stage, with updates expected in the second half of 2026. It is not approved and does not replace current treatments. Read the full article for clinical context, comparison with statins and PCSK9 inhibitors, and what these data mean for patients. Medical Disclaimer This article presents results from a Phase 1 clinical trial in an early-stage research phase. The therapy described is not approved and is not available as standard treatment.
