Why can laser be a problem in summer?
Tanned skin holds more pigment and absorbs more laser light. This may raise the chance of burns and later discolouration. Healing skin is also more sensitive to the sun.
With lasers that target pigment or hair, melanin in the skin absorbs the light. On recently tanned skin this absorption rises, and so does the risk of heat affecting non-target tissue.
The skin is also sensitive for a while after laser. Strong sun in this period can harm healing and colour balance.
Which laser treatments are riskier in summer?
Treatments that target melanin or put the skin through healing, such as hair removal, pigment laser and resurfacing, need more care. They may be planned for times when the sun can be avoided.
Treatments are not all alike. For hair removal on tanned skin, some devices may offer a more suitable wavelength and cooling; this depends on skin type and the device. Some doctors plan around the period before or after a holiday.
See the laser for different skin tones page for more on skin tone. For pigment treatment, seasonal planning matters even more.
What should someone who wants laser in summer keep in mind?
Avoid the sun before a session, stay away from sunbeds, tell the doctor about photosensitising medicines and apply sun protection strictly afterwards.
People with holiday plans should tell the doctor beforehand. If sun exposure between sessions is likely, it is good to discuss it openly. A session may be postponed if there is recent sunburn or tan.
After a session, broad-spectrum sunscreen, a hat and shade are the basic measures. See the sun protection and laser aftercare pages for details.
Why are autumn and winter considered easier?
Sun exposure and tan are lower, so risk is usually considered lower with lasers that target pigment or need healing. Sun protection still matters all year.
Season alone is not decisive. Skin type, daily sun exposure and working conditions also play a part. Snow reflection and high altitude can increase sun effect in winter too.
At consultation the doctor looks at the tan, any history of discolouration and the planned treatment together.
Frequently asked questions
Can laser hair removal be done in summer?
In some cases yes; tanned skin and sun exposure may raise risk. The doctor decides according to skin type and device.
Can I swim in the sea after laser?
Sun and seawater are usually avoided until the skin settles. The doctor who did the treatment sets the time.
How long before tanned skin returns to normal?
It can take weeks, depending on the person and sun exposure. The doctor's advice should be sought before a session.
Is sunscreen enough after laser?
Sunscreen is important but may not be enough on its own; shade, a hat and avoiding direct sun are also advised.
