IPL on the Bikini Line and Underarms: A Comfortable At-Home Guide
The bikini line and underarms are the two areas women most want to stop shaving, and the two they are most nervous about treating. They are sensitive, the hair is often thick and dark, and booking clinic sessions for them can feel awkward. The good news: IPL on the bikini line and underarms works very well at home, in complete privacy, as long as you prepare properly. Here is how.
Why these areas respond well to IPL
IPL targets the pigment in the hair. Underarm and bikini hair is usually dark and coarse, which gives the light a lot to work with. That is why many customers notice changes in these areas early. Results vary from person to person, but these are often the areas people are happiest with.
Where you can treat
- Underarms: the whole area, once shaved.
- Bikini line: the edges, the top line and the inner thighs.
- Brazilian area: the outer bikini area can be treated too. Avoid the inner, mucous areas.
Do not flash over tattoos, dark moles or darker patches of skin. If the skin in an area is naturally much darker, start on the lowest level and spot test there first.
How to prepare
- Shave the day before or the same day. Never wax, pluck or epilate during your IPL routine: the light needs the root in place.
- Skin clean and dry, with no deodorant, cream or powder. For underarms, shower and skip deodorant until after the session.
- Spot test on a small part of the area: 1 to 2 flashes per level, then wait 2 to 4 hours. Use the highest comfortable level with no lasting redness.
- Wear the safety glasses that come with your handset.
During the session: comfort tips
- Use Manual mode, which flashes each time you press. It gives you control in curved areas.
- Stretch the skin gently so the window sits flat. For underarms, raise your arm above your head.
- Go over each area 3 times, moving the window slightly between flashes.
- Choose a cooling handset if you are sensitive. The Ultra Sapphire IPL cools the skin at 0 to 1°C, and the ICE IPL at 0 to 5°C, which makes these areas much more comfortable.
After the session
A little pinkness is normal and fades quickly. Avoid hot showers, saunas, tight clothing and scented products on the area for the rest of the day, and wait until the next day for deodorant if your skin feels sensitive. Over the next 1 to 3 weeks, treated hairs will shed.
How many sessions?
Treat weekly for 6 to 12 weeks, then touch up every 2 to 3 months. Underarms and bikini line often need the full 12 weeks because the hair is thick. With the Ultra Sapphire, many users see a difference from the first session and clear results in 1 to 2 weeks; with the ICE, typically 4 to 6 weeks; with the Classic IPL, 6 to 8 weeks. See the full plan in how many IPL sessions you need.
Keep ingrown hairs away
Shaving these areas often causes ingrown hairs and bumps. Gentle exfoliation once or twice a week with the exfoliating glove helps keep skin smooth while your IPL routine reduces regrowth.
Safety reminders
Pause IPL during pregnancy and breastfeeding. Do not use it on tanned, sunburnt or irritated skin, or if you take medication that makes your skin sensitive to light. IPL works on brown, black, blonde and red hair, but not on grey or white hair.
Every handset comes with a one-year warranty, lifetime servicing and our 90-day money-back guarantee.
FAQ
Does IPL hurt on the bikini line?
It can feel stronger than on the legs because the hair is thicker. A cooling handset and Manual mode make it much more comfortable. Start on a lower level and build up.
Can I use IPL on the Brazilian area?
Yes, on the outer bikini area. Avoid the inner, mucous areas.
Can I wear deodorant before IPL on my underarms?
No. Treat clean, dry, product-free skin, and wait until after the session for deodorant.
How long until underarm hair stops growing back?
Most people see slower, finer regrowth within weeks, with full results after 6 to 12 weekly sessions and maintenance every 2 to 3 months. Results vary.
