Removing unwanted hair permanently is a common desire, and today technologies offer two main solutions: laser hair removal and intense pulsed light (IPL).
But what is the difference between the two? Which treatment is more effective? And most importantly, are they truly permanent?
Let’s explore every aspect together, from how they work to the actual results, including risks, costs, and useful guidance to make an informed decision.
How laser and IPL work: principles and differences
Both laser hair removal and IPL are based on the principle of selective photothermolysis: light is absorbed by the melanin in the hair and converted into heat, which destroys the hair follicle.
However, there are important differences between these two technologies.
Laser uses a single beam of light at a specific wavelength, more concentrated and targeted.
The most common type in beauty centers is the diode laser, but there are also alexandrite and ND:YAG lasers, each more or less suitable for different skin types.
Intense Pulsed Light (IPL) uses a polychromatic, non-coherent light that spreads across multiple wavelengths.
This makes it less targeted but more versatile and often available for home use as well.
Which is more effective: laser or IPL?
In terms of effectiveness, laser generally provides faster and longer-lasting results.
After 6–8 sessions, hair reduction can reach 80–90%, while IPL may require 10 or more treatments and regrowth is more likely.
Laser penetrates deeper and concentrates the energy more precisely on the hair bulb.
IPL, on the other hand, disperses some of the energy into the surrounding tissues.
However, the success of the treatment also depends on other factors: skin and hair color, device intensity, session frequency, and proper application.
Who are laser and IPL suitable for?
Both techniques work best on dark hair (rich in melanin) and light skin, where there is greater contrast.
Newer technologies (like ND:YAG laser) are safer even on darker skin, but it’s always essential to consult specialized centers.
People with white, grey, or red hair do not achieve good results, as there is little or no melanin to target.
In these cases, light-based technologies are not effective, and alternatives such as electrocoagulation may be considered.
Is it truly permanent hair removal?
The term “permanent” is often misused.
Both laser and IPL offer a permanent reduction in hair growth, but do not guarantee complete and forever-lasting removal.
Some follicles may remain dormant and reactivate over time, or regenerate due to hormonal changes.
It is common to need maintenance sessions once or twice a year.
However, compared to waxing or shaving, the hair becomes finer, sparser, and less visible, and the skin stays smooth longer.
How many sessions are needed and how often
On average, 6–10 sessions spaced 4–6 weeks apart are needed.
This is because laser and IPL only target hairs in the anagen phase (active growth), while at any given time only 20–30% of hairs are in this phase.
After the initial cycle, a maintenance treatment every 6–12 months is recommended to consolidate results.
Timings vary depending on the area treated: face, bikini line, underarms, and legs may respond differently.
Treatment costs
Costs depend on the technology used, the area being treated, and the number of sessions required. On average:
- Laser at a medical aesthetics center: from €50 to €200 per session, depending on the area
- IPL at a beauty center: from €30 to €150 per session
- Home-use IPL devices: from €150 to €500 for purchase
It's important to be cautious with very low-cost offers, which often hide poor-quality equipment or untrained staff.
Home treatments: pros and cons
In recent years, IPL devices for home use have become more widespread.
They are more affordable and convenient, but also less powerful.
This means results are slower and less lasting, and greater consistency is often needed.
It is also essential to read the instructions carefully and ensure the device is CE certified and approved for your skin type.
Among the most well-known brands are Philips Lumea, Braun Silk-Expert, and Beurer IPL.
Risks and contraindications
Although generally safe, both technologies carry risks if used improperly.
The most common risks include redness, burns, skin irritation, and hyperpigmentation.
To reduce these risks, it’s important to:
- Avoid sun exposure before and after treatment
- Avoid waxing and tweezing before sessions
- Respect the intervals between sessions
- Rely on qualified personnel or cosmetic doctors
Contraindications include pregnancy, breastfeeding, tanned skin, use of photosensitizing medications, epilepsy, active dermatitis, and certain hormonal conditions.
Which to choose: laser or IPL?
The choice depends on personal goals, budget, skin type, and time availability.
Laser is ideal if you're looking for faster, longer-lasting results, have a higher budget, and access to a specialized center.
IPL is more flexible and economical, also suitable for home treatments, but requires more patience and consistency.
Before starting, it is always recommended to consult a dermatologist to assess your skin type, hair type, and possible contraindications.
Laser and IPL hair removal are two effective solutions for drastically reducing hair growth over time.
Understanding the differences between these technologies will help you make an informed and safe choice, avoiding disappointments or risks.
The important thing is to proceed with awareness, relying on qualified professionals or certified devices.
Smooth skin is an achievable goal, but like any beauty treatment, it requires attention, care, and realistic expectations.
