For years, laser hair removal has been surrounded by myths whenever summer arrives.
Many clinics scale back their activity during the months of greatest sun exposure, and many
clients postpone their sessions thinking that “now is not the right time”.
But the reality is different.
With the right technology and by following correct clinical protocols, laser hair removal
can be carried out all year round, even in summer, safely and effectively.
In this article we explain why.
Can laser hair removal be done in summer?
Yes.
What is unsafe is not summer itself, but treating skin that has been exposed to the sun
without control, or using inappropriate parameters.
Laser hair removal works through the principle of selective photothermolysis:
the laser’s energy is absorbed by the melanin in the hair follicle, is converted into heat
and destroys the cells responsible for hair growth without damaging the surrounding tissue.
The problem appears when:
- The skin has been tanned recently.
- There is active solar erythema.
- The parameters are not correctly adjusted to the skin type.
That is why the key is not “stopping treatment in summer”, but knowing how to do it correctly.
What changes in summer (and how to manage it correctly)
In summer, many skins temporarily rise in skin type because of tanning. This entails a higher
concentration of epidermal melanin and, therefore, greater risk if the treatment is not adjusted.
To work safely it is essential to:
1. Assess the skin before each session
Skin with redness, inflammation or active sun damage must not be treated.
2. Respect the sun exposure guidelines
It is recommended to avoid direct sun exposure for at least 15 days before and 15 days after
each session. This measure significantly reduces the risk of pigmentary changes and makes it possible to
work on skin in optimal condition.
In addition, throughout the treatment it is essential to use high sun protection (SPF 50+),
especially on exposed areas such as the face, décolletage and arms. The use of protective clothing is
also advised, as well as avoiding tanning beds.
3. Adjust the parameters correctly
On low skin types (I–III) it is possible to work with shorter pulses.
On higher skin types (IV–VI) or tanned skin, longer pulses are used to heat the
follicle gradually and protect the epidermis.
4. Carry out a patch test if there is any doubt
On recently sun-exposed skin, a prior test on a discreet area provides additional safety.
When these protocols are followed correctly, the treatment can continue as normal.
The importance of technology in summer
Not all laser devices offer the same level of control or safety.
An 810 nm diode laser makes it possible to reach the full depth of the hair follicle, ensuring
effectiveness even when we have to adjust parameters because of seasonal tanning.
In addition, a continuous cooling system with a sapphire tip keeps the epidermis protected
during the shot, something that is especially important during the months of greatest sun exposure.
When the technology makes it possible to:
- Adjust fluence with precision
- Modify pulse duration according to skin type
- Work with constant cooling
- Maintain stability during prolonged sessions
summer stops being a limitation.
What you should not do in summer
One of the most common mistakes is lowering the energy excessively “out of fear”.
Working with fluences that are too low can:
- Reduce effectiveness
- Miniaturise the hair
- Encourage the so-called paradoxical effect (hair appearing in adjacent areas)
The solution is not to work with less power, but to work with controlled power and
well-adjusted parameters, always respecting the recommendation to avoid the sun for 15 days
before and after each session.
So, is it safe to do laser hair removal all year round?
Yes, provided that:
The skin is healthy and free of active sun damage- Direct sun exposure is avoided for 15 days before and 15 days after
- The parameters are adapted to the real skin type at that moment
- Suitable technology with thermal control is used
- The client follows the sun protection recommendations
Summer is not a contraindication.
The lack of a protocol is.
Conclusion
Laser hair removal all year round is not only possible, but is also a safe practice when
it is carried out with professional judgement and suitable technology.
Suspending treatments for months can prolong results unnecessarily.
By contrast, maintaining continuity with correct technical adjustments makes it possible to optimise
timescales and results without compromising safety.
Because the key is not the season of the year.
It is in how you work.
