LED Light Therapy – What Each Colour Really Does for Your Skin

LED Light Therapy: What Each Colour Really Does for Your Skin

LED light therapy is now a well-versed treatment in the skincare world  — and for good reason.  LED therapy is safe, painless, and effective. This non-invasive treatment uses different wavelengths (colours) of light to target specific skin concerns. But with all the colours out there, it can be confusing to know which one does what.

Here’s a simple guide  — colour by colour — so you can choose the right one for your skin goals.

🔴 Red Light (620–750 nm): Anti-Aging Hero

What it does:
Red light penetrates deep into the skin to stimulate the production of collagen and elastin. It helps reduce fine lines and wrinkles, improve skin elasticity, and speed up healing.

Best for:

• Fine lines & wrinkles
• Loss of firmness
• Redness and inflammation
• Post-treatment healing

Bonus: Red light therapy is great for sensitive skin — think rosacea or post-laser recovery.

🔵 Blue Light (405–470 nm): Acne Fighter

What it does:
Blue light targets acne-causing bacteria (Propionibacterium acnes) on the skin’s surface, helping to reduce breakouts and inflammation without drying the skin out.

Best for:

• Acne
• Oily or congested skin
• Enlarged pores

Caution: Can be drying for sensitive skin if overused, so balance is key.

🟢 Green Light (525–550 nm): Skin Tone Balancer

What it does:
Green light helps to reduce hyperpigmentation by calming overactive melanin-producing cells. It evens out skin tone and can reduce redness or blotchiness.

Best for:

• Hyperpigmentation
• Age spots
• Redness or uneven tone
• Dark circles

Pro tip: Combine with red light for anti-aging + brightening benefits.

🟡 Yellow Light (570–590 nm): Skin Soother

What it does:
Yellow light penetrates deeper than green and works to reduce redness, soothe sensitive skin, and improve lymphatic flow.

Best for:

• Rosacea
• Red or irritated skin
• Post-treatment calming
• Sensitive or allergy-prone skin

Think of it as the “comfort light” for stressed skin.

🔮 Purple (Red + Blue Combo): Dual Action Repair

What it does:
Combines the benefits of red and blue light — reducing inflammation and killing acne bacteria while also promoting skin healing and anti-aging.

Best for:

• Acne-prone mature skin
• Breakouts with scarring
• Combination skin types

⚪ White Light (Full Spectrum ie: all colours ): Deep Skin Repair

What it does:
White light is a combination of all visible wavelengths and penetrates the deepest. It stimulates skin renewal and can assist with overall skin repair and tone.

Best for:

• Deep wrinkles
• Skin laxity
• Dull, tired-looking skin

Many people ask – Do LED treatments really work?  Short answer, they do, but results come with consistency

Professional-strength LED treatments are always the best option, and visiting a professional to understand what each colour does helps you treat the right concern at the right depth. Professional devices used in clinics deliver higher light intensities and often penetrate deeper into the skin, resulting in faster and more noticeable results.

LED home devices can have some effect for maintaining skin health, but they are generally not as powerful or targeted as professional-grade treatments.  At-home devices, while convenient and more affordable, usually operate at lower energy levels to ensure safety for untrained users.

At ENRICH DIV we can help. Many of our laser treatments include an LED treatment, or you can try the LED treatment on its own.
