How Many LED Sessions for Acne?

Medically reviewed by Gabi, Aesthetic Clinician · Last reviewed 5 July 2026

LED light therapy is a popular option for acne-prone skin because it’s non-invasive, comfortable and has no downtime.

The right number of sessions depends on how active the breakouts are, whether acne is mild/moderate, and how consistent you can be with treatments and home care.

Typical course structure

Many clinics recommend starting with a short course of sessions close together, then reducing frequency once skin is calmer. This is because LED effects are cumulative.

Blue + red combination

Blue light is commonly used for active breakouts, while red light can support comfort and recovery. Combining wavelengths is often used in clinic acne protocols.

What affects the number of sessions

Severity, skin sensitivity, lifestyle factors, and whether you’re using topical or prescription acne products can all change the ideal schedule.

Maintenance

Once acne is under control, many people switch to maintenance sessions to help keep skin stable, especially during stressful periods or hormonal changes.

What else matters

LED works best alongside a simple routine: gentle cleansing, non-comedogenic moisturiser, and SPF. Avoid harsh over-exfoliation which can trigger irritation and breakouts.

FAQ

How many LED sessions do I need for acne?

Most people do best with a course of sessions close together at the start, then maintenance. The exact number depends on how active your breakouts are and how your skin responds.

Is blue light therapy good for acne?

Blue light is commonly used for acne-prone skin, especially for active breakouts. Many plans combine blue and red wavelengths.

How quickly will I see improvement?

Some people notice calming within a few sessions, but acne improvement is usually gradual and benefits from consistency.

Can I do LED while using acne skincare or medication?

Often yes, but suitability depends on what you’re using and whether it causes photosensitivity or irritation. A consultation helps tailor a safe plan.

Does LED help acne scars?

LED is mainly used for active acne and skin comfort. Scar improvement usually needs a broader plan; LED can be a supportive addition.

Can LED replace facials or extractions?

LED can complement facials, but it’s not the same as extractions or medical acne treatments. Combining the right tools usually works best.
