Red Light Therapy for Neck and Chest (Decollete)

The neck and chest (decollete) often show age before the face, yet most skincare stops at the jawline. Thin skin, sun exposure, and "tech neck" lines make this area a common concern, and red light therapy treats it the same way it treats the face.

Why the decollete ages quickly

Skin here is thin, has fewer oil glands, and gets heavy sun exposure, so collagen breaks down fast, leaving crepey texture and vertical lines. Red light stimulates new collagen to firm and smooth the area. See the collagen science for how it works.

Best device for the neck and chest

This is a larger, flatter area, so a panel often covers it better than a face mask. Position a panel 6-12 inches away for 10 minutes per session. If you mainly want face plus neck, a mask that extends to the neck also works. Compare options in our skin guide.

Consistency wins

Treat 4-5 times per week and give it 8-12 weeks. Pair with daily SPF, since sun undoes collagen gains.

A panel covers the broader neck-and-chest area more evenly than a mask. The AWA FX300 Red Light Therapy Panel ($199.99, FSA/HSA eligible) is a great fit. See how to use your FSA/HSA to save 30-40% with pre-tax dollars.

FAQ

Can I use my face mask on my neck and chest?

Partly. Masks cover the face and upper neck; a panel covers the full chest better.

How long until crepey skin improves?

Expect gradual smoothing over 8-12 weeks with consistent use and daily SPF.
