Understanding Infrared, Red, and Blue Light Technologies in Skincare

Light therapy has become a trusted part of modern skincare routines, especially for those seeking gentle, effective, and science-backed solutions. If you’ve ever wondered about the differences between red vs blue light therapy, or how infrared light therapy skincare works, you’re in the right place. This article explains skincare light technology in simple terms, focusing on the most popular LED light therapy types and how they can help you achieve healthier, more radiant skin.

What Is LED Light Therapy? Skincare Light Technology Explained

LED light therapy uses specific wavelengths of light to target different skin concerns. Unlike UV rays, these lights are safe, gentle, and do not cause skin damage or downtime. The technology was first studied by NASA for wound healing and has since become a favorite in both clinics and at-home devices.

LED light therapy types include red, blue, and infrared light, each with unique benefits for the skin. These treatments are non-invasive and suitable for most skin types, making them a popular choice for customers looking for visible results without harsh procedures.

Red Light Therapy: The Anti-Aging Powerhouse

Red light therapy is best known for its ability to support collagen production, reduce fine lines, and improve skin texture. The red wavelengths (typically 630–700nm) penetrate deep into the dermis, stimulating fibroblasts—the cells responsible for collagen and elastin.

How Red Light Therapy Works

• Boosts Collagen and Elastin: Red light encourages the skin to produce more collagen and elastin, which helps keep skin firm and smooth.
• Reduces Inflammation: It calms redness and soothes sensitive or reactive skin, making it ideal for those with rosacea or post-inflammatory marks.
• Speeds Up Healing: Red light therapy can help skin recover from damage, including sun spots, scars, and even minor wounds.

Consistent sessions—ideally 10 minutes, three to five times a week—are key for the best results. Solawave’s red light therapy devices are designed for easy, at-home use and deliver gentle, effective treatments with no downtime or risk of UV damage. For those looking to enhance their results, pairing your device with the Lightboost Red Light Therapy Hyaluronic Serum can help boost hydration and support your skin’s renewal process.

Blue Light Therapy: The Acne Solution

Blue light therapy targets the uppermost layer of the skin (epidermis) and is especially effective for acne-prone skin. The blue wavelengths (420–490nm) work by killing acne-causing bacteria and regulating oil production.

How Blue Light Therapy Works

• Fights Acne: Blue light destroys the bacteria responsible for breakouts, helping to clear existing acne and prevent new pimples from forming.
• Reduces Oiliness: It helps control sebum (oil) production, making it a favorite for those with oily or combination skin.
• Calms Inflammation: Blue light also soothes irritated skin and reduces redness, which is helpful for inflamed acne lesions.

Blue light therapy is often combined with red light for a complete approach to clearer, healthier skin. Devices like the Radiant Renewal Skincare Wand offer both red and blue light options for targeted results.

Infrared Light Therapy: Deep Skin Rejuvenation

Infrared light therapy skincare is gaining attention for its ability to reach the deepest layers of the skin. Infrared wavelengths (700–1200nm) go beyond what the eye can see, working below the surface to boost blood flow, promote cell regeneration, and support overall skin vitality.

Benefits of Infrared Light Therapy

• Improves Circulation: Enhanced blood flow brings more nutrients and oxygen to skin cells, supporting a healthy, glowing complexion.
• Promotes Healing: Infrared light helps with wound healing and can improve the appearance of scars and fine lines.
• Soothes Discomfort: It’s also used for relief from muscle soreness and stiffness, making it a favorite for those seeking both beauty and wellness benefits.

Red vs Blue Light Therapy: Which Is Right for You?

When comparing red vs blue light therapy, it’s important to consider your main skin concerns:

• Red Light Therapy: Best for anti-aging, reducing fine lines, improving skin texture, and calming inflammation.
• Blue Light Therapy: Best for treating and preventing acne, controlling oil, and reducing redness from breakouts.
• For many, a combination of both therapies offers the most complete results. If you’re looking to address both aging and acne, devices that offer multiple LED light therapy types are a smart choice.

How to Use LED Light Therapy at Home

LED light therapy is easy to add to your skincare routine. Here’s what you need to know:

• Session Duration: Most at-home devices recommend 10-minute sessions for each treatment area.
• Consistency Matters: For visible results, use your device three to five times a week. Once a week is not enough for most customers to see the changes they want.
• No Downtime: Treatments are 100% gentle, with no risk of UV damage or recovery time needed.
• Pairing with Skincare: For best results, use your device on clean skin. You can follow up with serums like the Lightboost Red Light Therapy Hyaluronic Serum, Lightboost Collagen Caffeine Eye Cream, Lightboost Face and Neck Cream, or Lightboost Niacinamide Face and Neck Serum to boost hydration and support your skin’s renewal process.

Solawave’s shop offers a variety of devices and skincare products to help you build a routine that fits your needs and lifestyle.

What Results Can You Expect?

Customers often report improvements in skin texture, reduced fine lines, and a brighter complexion after a month of consistent use. For acne, blue light therapy can reduce breakouts and calm redness, while red and infrared light support overall skin health and healing.
