Understanding LED Light Therapy: Causes, Types, and When to Seek Medical Help

Understanding LED Light Therapy

LED (Light Emitting Diode) light therapy is a cosmetic treatment that uses different colours of light to target specific skin concerns. It is completely non-invasive, pain-free, and suitable for all skin types. The therapy stimulates natural cellular processes to help the skin heal and renew itself.

Originally developed by NASA, LED therapy is now widely used in skincare clinics and beauty salons.

What Is LED Light Therapy?

This treatment involves the application of light to the face or body using a panel, handheld device, or face mask. Different light wavelengths have different effects:

Red Light – Stimulates collagen, reduces fine lines, and improves skin elasticity

Blue Light – Kills acne-causing bacteria and reduces breakouts

Green Light – Helps reduce pigmentation and even out skin tone

Yellow Light – Soothes sensitive skin and reduces redness

Sessions usually last 20–30 minutes, often as part of a facial or standalone treatment.

What to Expect from an LED Light Therapy Service

During your LED light therapy appointment, you can expect:

A brief skin consultation

Cleansing of the treatment area

Application of the LED device over the skin

Relaxation during light exposure (typically 20–30 minutes)

Application of serums or moisturisers post-treatment

No downtime is required, and results improve with repeated sessions.
