Red Light Therapy: Skincare Benefits

What is Red Light Therapy?

Red light therapy (RLT) utilizes low-level wavelengths of red or near-infrared light (typically 630–700 nm) to stimulate cellular activity in the skin. Unlike UV light, RLT doesn’t damage the skin or increase the risk of cancer.


Skincare Benefits

  • Reduces Inflammation: RLT helps decrease redness and swelling, making it beneficial for conditions like acne and rosacea.

  • Boosts Collagen Production: It stimulates fibroblasts to produce more collagen, improving skin elasticity, reducing fine lines, and enhancing overall texture.

  • Improves Healing: RLT promotes wound healing, fades scars, and can reduce psoriasis symptoms.

  • Refines Pores and Tone: Regular use can help reduce pore size and give the skin a firmer, more youthful appearance.


At Dermaesthetics, we use red light therapy for:


  • Reducing wrinkles, fine lines, and age spots.

  • Improving facial texture.

  • Enhancing conditions like psoriasis, rosacea, eczema, and acne.

  • Helping to improve scars and sun-damaged skin.

  • Promoting hair growth in individuals with androgenic alopecia.

  • Reducing stretch marks.


How to Choose a Red Light Therapy Device

  • Wavelength: 620–700 nm for skin; 630–660 nm ideal for surface-level benefits.

  • Power Output/Irradiance: Over 100 mW/cm² for effective results.

  • Safety Features: Built-in timers, automatic shut-off, and eye protection.

  • FDA Clearance: Ensures safety and efficacy standards.


Types of Light Therapies and Their Uses

  • Red Light (630nm): Rejuvenates skin, stimulates collagen, and lightens pigmentation spots.

  • Blue Light (470nm): Targets acne, calms the skin, and tightens pores.

  • Green Light: Reduces inflammation, helps with pigmentation, and may promote healing. It’s also useful for migraines and calming skin redness.

  • Yellow Light: Soothes irritation, reduces redness, and aids in skin rejuvenation. It helps reduce hyperpigmentation and even out skin tone.

  • Purple/Violet Light: Combines red and blue benefits, useful for acne and delaying signs of aging.

  • Cyan/Turquoise Light: Calms the skin, reduces irritation, and helps with sun damage recovery.


Risks and Side Effects


Red light therapy is generally safe, but some mild side effects may occur:


  • Skin Irritation: Temporary redness or mild irritation, especially for sensitive skin.

  • Headache or Eye Strain: Use protective goggles to avoid discomfort or potential eye damage.

  • Burns or Blistering: Rare, usually due to high intensity or improper use.

  • Increased Bleeding: Avoid use on open wounds that haven’t fully healed.


Tips for Safe Use


  • Follow the device’s instructions carefully.

  • Always use eye protection.

  • Start with shorter sessions (5-10 minutes) and gradually increase to 20 minutes, up to 3 times per week.

  • Stay hydrated to minimize discomfort or headaches.


Red light therapy is a promising, non-invasive option for improving skin health, reducing inflammation, and supporting anti-aging routines. Make sure to use FDA-approved products under the guidance of a trusted health professional.
