So I got a red light panel (Koanna Luma300 - I‘m not in the US so I had limited options) and want to use it to improve my skin. I have Rosazea and POD as well as some slight acne and combination skin. Also some laugh lines and I just wanted to improve the elasticity etc.

There’s SO much information on here regarding the usage and i’m so overwhelmed. I tried asking Chat GPT which Settings I should use but I‘m even more confused now.

Maybe there’s a Red Light Expert on here who can help me?

ChatGPT recommended the following:

Red Light Protocol for Skin

(Rosacea stability + collagen support + overall skin quality)

Device Settings

Wavelengths: 660 nm (red) + 810–850 nm (near-infrared)

Mode: Continuous (0 Hz)

Distance: 25–30 cm

Power: 40%

Duration: 60 seconds

Frequency: 3–5 times per week

Evaluation period: 4–6 weeks

This delivers approximately 2–3 J/cm² per session, which falls within the most consistently supported dermatological photobiomodulation (PBM) range.

⸻

Why this dose?

Photobiomodulation follows a biphasic dose–response curve (Arndt–Schulz principle):

Too little → no meaningful effect

Optimal range → anti-inflammatory signaling + mitochondrial stimulation

Too much → diminishing returns or reduced biological response

For:

Rosacea and vascular sensitivity

Collagen stimulation

Skin texture and firmness

Most clinical LED studies show beneficial effects in the range of 2–5 J/cm² per session.

Your panel is relatively high-output.

At 60% for 2 minutes, you would already reach ~8 J/cm² — which exceeds the typical dermatologic “sweet spot” and is unlikely to provide additional benefit for rosacea-prone skin.

What do we think? Good recommendation??

I could also post the technical specifications of the panel if needed 🫠 I’m thankful for any tips/help!!
