Does Red Light Therapy Really Help Your Skin?

Here’s what you need to know...from glowing celebrity endorsements to high-tech home devices, red light therapy has become the buzzword in beauty. But does it actually work? Or is it just another trend that looks great on TikTok? We did some digging to find out!

//What is red light therapy?

Red light therapy (RLT) is also known as low-level laser therapy or photobiomodulation and uses specific wavelengths of red and near-infrared light to stimulate the skin at a cellular level. When absorbed by the skin, the light energy is believed to boost the mitochondria, the “powerhouse” of our cells, encouraging increased production of ATP (the energy currency of cells), which helps with regeneration and repair.

Sounds science-y? That’s because it is. But the good news is that it’s safe, non-invasive and pain-free.

//What can it do for your skin?

The real appeal of RLT lies in its versatility. Here’s what consistent use may offer:

• Boost collagen production: Red light therapy can help stimulate fibroblasts, the cells that produce collagen and elastin. More collagen = firmer, plumper skin with fewer fine lines and wrinkle – yes please!

  
  

• Improve skin tone and texture: Many users notice a smoother, more radiant complexion over time. It’s like a filter, but in real life.

  
  

• Reduce inflammation and redness: Great news for those with sensitive skin, rosacea or post-acne flare-ups. RLT can calm irritated skin and support the healing process.

  
  

• Accelerate wound healing: Clinical studies have shown that red light may help skin recover faster after treatments like microneedling or even sunburn.

  
  

• Tackle breakouts: While red light is not a replacement for acne treatments, it can reduce inflammation associated with breakouts and support skin clarity over time.

//Does it really work?

Here’s the thing: red light therapy isn’t a magic wand, but it is backed by promising research. Studies published in journals like The Journal of Photochemistry and Photobiology have shown significant improvements in skin texture, elasticity and wrinkle depth with regular use.

Consistency is key. It’s not a one-time fix; you’ll need to use it several times a week over several weeks (or months) to see results. Most people start noticing improvements within 4–8 weeks.

//Can I use it at home?

Yes! While many clinics offer red light facials, at-home devices are now widely available, ranging from full face masks to handheld wands. Just be sure to invest in a quality, FDA-cleared product and always follow usage guidelines.

If you’re looking for a non-invasive, relaxing and science-backed way to support your skin’s health, red light therapy could be worth the glow-up. It’s not a replacement for SPF or a balanced routine, but as part of your skincare toolbox? It might just be the (red) light at the end of the tunnel.
