How to Choose a Starting IPL Level

A simple overview of the key factors to consider before selecting your starting IPL level.

Choosing the right starting energy level is one of the most important first steps when using an at-home IPL device. A gradual, controlled approach helps you stay comfortable, stay consistent, and build a routine you can actually follow—especially in the first few sessions.

If you want a quick “level mindset” reference, you can also use Choose Your Energy Level on MITHLUX S2 PULSE alongside this guide.

Why your starting level matters

IPL works by delivering light energy through the skin surface to target hair in its active growth phase over time. Starting at an appropriate level helps your skin adapt while you learn what “comfortable and repeatable” feels like.

Starting too high can create unnecessary discomfort and make you want to take breaks (breaks slow progress the most).
Starting too low may feel easy, but it can lead to slower visible changes—especially in early weeks.
The best starting level is the one you can use consistently without irritation.

A simple way to choose your first level

For most beginners, the safest strategy is to begin low and increase gradually based on how your skin responds. If you’re unsure, use this rhythm:

Start low for the first session on that area.
Pay attention during the session (comfort matters more than “pushing through”).
Check your skin later (how it looks and feels a few hours after matters most).
Increase slowly only if comfort stays stable session to session.

When to stay lower for longer

Skin tone, hair thickness, body area, and your personal sensitivity can change how IPL feels. It’s usually smart to stay at a lower level for multiple sessions if:

Your skin is easily irritated or reacts to new products quickly.
You’re new to light-based devices or returning after a long break.
You’ve had recent sun exposure (even mild tanning can change sensitivity).
You’re treating more sensitive areas and want a steady, repeatable routine first.

Patch test before full use

Before treating a larger area—especially your first time, or before moving up a level—do a patch test:

Choose a small test spot on the area you plan to treat.
Use a lower level than you think you’ll use long-term.
Wait at least 24 hours, then check how the skin feels.

How to increase over time

As your skin becomes familiar with IPL, you can increase the level gradually when appropriate. There’s no need to rush—comfort and consistency matter more than reaching a high level quickly.

Increase one step at a time, not multiple jumps.
Hold steady for a few sessions after an increase to confirm your skin stays calm.
Step down if you notice extra sensitivity, dryness, or discomfort.

Everyone’s IPL experience is different. The most reliable approach is to listen to your skin and adjust gradually. For complete instructions and safety guidance, refer to the official MITHLUX S2 Pulse User Manual.
