How much effort is IPL? Time, routine and results explained

How much time does at-home IPL take?

Treatment time depends on a number of factors including…

• the number and size of the areas.
• the device’s flash speed.
• the selected setting.
• your technique.

For instance, your underarms will take less time than treating both legs.

There is no medically established full-body time that applies to every home IPL device, so estimates should not be treated as universal.

You should also include preparation time when planning a session. This may include things like:

• removing visible hair.
• washing and dry the skin.
• set up the device and attachment.
• treating each area methodically.
• cleaning and store the device.
• recording the next treatment date.

Home treatment avoids travel and salon waiting time. However, larger areas still need enough time for even coverage. Rushing or repeatedly flashing the same spot is not an effective shortcut.

What happens during the first 12 weeks?

IPL directs light towards melanin in the hair. The light is converted into heat within the hair, helping to slow future regrowth.¹ Because hairs are not all in the same growth phase at once, repeated sessions are needed. Only hairs in the active growth phase respond effectively, which is why one session cannot treat every hair.²

For Philips Lumea, the routine normally begins with four treatments at two-week intervals, followed by touch-ups at four-week intervals. The first 12 weeks may therefore look like this:

• Weeks 0, 2, 4 and 6: initial treatments.
• Around week 10: first touch-up.
• Afterwards: continue at the interval stated for your model.

Device schedules are not interchangeable, so follow the instructions for your exact model.

How much effort does the routine require?

Once you know the steps, an IPL session can follow a straightforward and repeatable process. Start with a one-time suitability check, followed by five treatment stages.

Stage 0: Check suitability before starting

Confirm that the device is suitable for your skin tone, hair colour, treatment area and health circumstances. Read the contraindications before your first treatment.

This is an initial setup step rather than part of every session. Review your suitability again if something changes, such as your medication, health circumstances, tanning status or skin tone.

Stage 1: Complete a skin test

Test each new area and wait for the period specified in the instructions before completing a full treatment.

Stage 2: Prepare the skin

Remove visible hair, then ensure the area is clean, dry and free from deodorant, lotion, oil or make-up.

Stage 3: Prepare the device and select the setting

Fit the correct attachment and use the recommended or previously tested intensity. A higher setting is not better if it is uncomfortable or unsuitable.

Stage 4: Treat systematically

Work in orderly lines to reduce missed sections. Maintain proper skin contact and do not intentionally flash one spot repeatedly.

Stage 5: After treatment

Record the areas you treated and schedule the next session. Then follow the instructions for skincare, heat and sun exposure, and clean and store the device as directed.

The Philips Lumea 9900 Pro IPL can connect to the Lumea app for real-time coaching. During a guided session, audio and visual feedback supports movement, positioning, skin contact and coverage. Afterwards, the app records progress and produces a treatment report. This can reduce the effort involved in remembering each step and help you refine your technique as you become more familiar with the routine.

Is IPL less effort than shaving or waxing?

IPL requires more planning during the initial treatment phase but usually involves less frequent hair-removal activity later than other methods. Whether it feels easier depends on the areas treated, personal hair growth and your routine.

Shaving results are often short-lived and may require daily use or use every few days. Waxing removes hair from the root and can provide results lasting about three to four weeks.³ However, waxing still needs to be repeated and may also involve booking appointments, travelling to a salon and allowing time for the treatment itself.

IPL can therefore require less ongoing effort in the long-term, particularly if you prefer treating yourself at home. Results develop gradually, although the Lumea 9900 Pro can deliver more than 80% hair reduction after just two sessions.*

When can you expect IPL results?

When using an IPL device, expect gradual change rather than an immediate hair-free result. Also, keep in mind that different body areas can respond at different rates because their hair-growth cycles differ.¹

Results may vary according to¹:

• Hair colour and thickness.
• Skin tone and device suitability.
• Body area.
• Preparation and coverage.
• Adherence to the schedule.
• Hormonal or medical factors.

How can you keep your IPL routine on track?

A few simple habits can help make each session consistent and effective:

• Follow the full initial treatment schedule.
• Remove visible hair and skincare products before treatment.
• Use a tested, comfortable intensity.
• Move across the skin in a clear, methodical pattern.
• Flash each position only as directed.
• Follow the device’s suitability and safety guidance.
• Complete touch-up treatments at the recommended intervals.
• Keep a record of the areas treated and your next session dates.

Frequently asked questions

Does every session take the same amount of time?

No. Treatment time varies according to the area, device, setting and technique. As you become familiar with the device and develop a consistent coverage pattern, sessions may feel easier and more efficient.

The Philips Lumea app also provides treatment reports, allowing you to review your sessions, track progress and improve your technique over time. Your first few sessions will therefore provide a better personal estimate than a generic full-body treatment time.

Can I split treatments across different days?

Usually, suitable areas can be treated on separate days, provided each follows the correct interval. Keep a record for every area.

What happens if I miss a session?

Do not compensate by treating repeatedly or using a higher intensity. Resume according to the missed-treatment guidance for your device.

Is IPL less work than waxing?

It can be over time. Waxing can keep skin smooth for several weeks, but it still needs to be repeated and may involve booking an appointment, travelling to and from the salon, and waiting and allowing time for the treatment itself.³

At-home IPL has a concentrated initial phase, but it can be completed around your own schedule without salon visits. This is followed by less frequent touch-up treatments for users who achieve a good response.

IPL effort is mostly front-loaded, but that initial commitment can lead to less frequent hair-removal later. Follow the exact schedule and instructions supplied with your device to make the routine as straightforward and effective as possible.
