Laser hair removal under the Hawaiʻi sun: when to start
By the Foley OB & Aesthetics team · Published
The short answer
Start when you can keep the treatment area out of the sun. The laser targets pigment in the hair, and a tan adds pigment to the skin around it, which raises the risk of the skin darkening or lightening. Mayo Clinic advises avoiding sun and tanning before treatment, and protecting treated skin from the sun for six weeks after each session or as your provider directs.
Why the sun matters for laser
Mayo Clinic notes that skin color changes after laser hair removal are usually temporary but can be lasting in rare cases, and the risk is higher in people who don’t avoid sun exposure before or after treatment. On Oʻahu, beach days don’t stop for winter, so timing is less about the season and more about your plans.
Before each session
- Avoid sun exposure and tanning beds on the area being treated.
- Skip spray tans and sunless tanning products.
- Wear a broad-spectrum, water-resistant sunscreen with SPF 30 or higher every day.
- Stop waxing, plucking or electrolysis at least four weeks before treatment. Shaving is fine.
- Shave the area the day before your appointment.
- Tell your provider about a recent tan, a tendency to scar, cold sores or any medications you take.
After each session
Some redness and swelling for a few hours is common. Protect the treated skin from the sun for six weeks or as directed, and keep using SPF 30 or higher every day between sessions.
Planning around island life
- Areas you usually keep covered, such as the underarms and bikini line, are easier to keep out of the sun than legs or the face.
- Book sessions so a big beach trip or a wedding in the sun doesn’t land right before or after an appointment.
- Cover treated areas with clothing on the beach, the boat or the trail, and reapply sunscreen.
- If your skin is darker than usual on the day of your session, mention it at check-in.
