Skin prep is mainly about three things: confirming suitability, starting conservatively, and using consistent technique. These steps help reduce avoidable irritation and make your routine easier to repeat. [1] [2] [3]

If something feels unusual (strong pain, unexpected burning, or a strong reaction), pause and reassess before continuing.

Checklist

  • Start with suitability basics. Skin phototype and hair pigment influence how light-based hair reduction is typically approached. [1] If you’re unsure, review the Skin & Hair Guide.
  • Read your user manual first. Use the manual as the primary source for device-specific limits and operating steps: User Manual.
  • Patch test before full sessions. This is especially important when you’re new, sensitive, or restarting after a long break: How do you perform a patch test before IPL?.
  • Increase gradually only if skin stays calm. Conservative starts help you judge comfort and avoid over-treating early on: Starting level guide.
Practical rule: If you can’t comfortably repeat the same routine for 4–6 weeks, the level or technique is likely too aggressive.

24–48 hours ahead

These steps reduce avoidable irritation and help you stay consistent. If your skin is already irritated or recently tanned, it’s usually better to wait.

  • Avoid recent sun exposure and tanning. Recently tanned or sunburned skin may be more reactive, so delaying is often the conservative choice. [3]
  • Skip harsh exfoliation. Avoid aggressive scrubs, peels, or abrasive tools on areas you plan to treat.
  • Keep skin calm. If the area is already irritated, wait until it returns to normal before treating. [2]
Conservative default: If you’re unsure, verify suitability first via the Skin & Hair Guide (and then follow your device manual).

On the day of your session

A clean, dry surface helps light delivery stay consistent and makes it easier to judge comfort.

  • Shave the area. IPL is typically used on shaved skin. Do not wax, pluck, or epilate beforehand: Shave the Area Before Using MITHLUX.
  • Clean and dry. Remove lotions, oils, deodorant, fragrance, or makeup from the treatment area.
  • Do not use numbing cream. If normal sensation is reduced, it’s harder to judge comfort and stop early.
  • Remove accessories. Take off jewelry around the treatment area.
  • Protect your eyes. Use protective eyewear if included and follow device instructions.

During your session

Technique matters. Good contact and steady movement usually reduce “hot spots” and improve consistency.

Level choice: Use the 6 energy levels + area guide and increase gradually only when sessions stay comfortable.

After your session

Keep aftercare simple and avoid extra stress on the treated area for the rest of the day.

  • Keep it simple. Use gentle skincare and avoid irritants for the rest of the day.
  • Avoid heat and friction. Skip hot showers, saunas, and intense workouts if skin feels warm or sensitive.
  • Moisturize if needed. If skin feels dry, use a mild, fragrance-free moisturizer.
  • Sun protection matters. If treated skin will be exposed, minimise UV exposure and use sun protection as appropriate. For a practical routine, see Aftercare & Results. [3]

Common prep mistakes to avoid

  • Using IPL on skin that is sunburned, freshly tanned, or already irritated.
  • Applying lotions, oils, deodorant, or fragrance right before treatment.
  • Plucking or waxing shortly before IPL (it can reduce effectiveness because the hair root is removed).
  • Jumping to a high level too fast instead of building up gradually: How to Choose a Starting Level for Home IPL.
  • Flashing the same spot repeatedly in a short time: What mistakes should you avoid with at-home IPL?.
If you react: Pause and review what to do if your skin reacts badly.
