Seven Wavelengths

Light is not one thing.

Seven precisely tuned wavelengths — each reaching a different depth, each with a distinct purpose. The same wavelengths studied in clinical LED research.

630nm

Red Light

Supports the skin's surface appearance — tone, texture, the visible signs of time.

830nm

Near-Infrared

Reaches deeper — invisible to the eye, working where firmness begins.

415nm

Blue Light

Works at the skin's surface to help clarify and balance blemish-prone skin.

525nm

Green Light

Targets the look of hyperpigmentation and uneven skin tone.

590nm

Yellow Light

Supports the appearance of redness and skin radiance.

405nm

Purple Light

A dual-action wavelength combining red and blue for comprehensive support.

470nm

Cyan Light

Soothes the appearance of irritated skin and supports an even complexion.

Questions

Before you begin.

How long until I see a difference?
Most LED research protocols run 4–8 weeks of consistent use, 3–5 sessions per week. Take a photo on day one — your mirror will lie to you, your camera won't.
Is it safe for sensitive skin?
LED light therapy is non-UV and generally well tolerated. If you are pregnant, photosensitive, or taking photosensitizing medication, consult your physician before use.
Does it replace my skincare routine?
No — it amplifies it. Use on bare skin, then apply your serums after. The ritual fits inside the routine you already have.
What if it's not for me?
You have 30 days. If the ritual isn't yours, return it for a full refund — no interrogation, no restocking fee.
How fast is shipping?
Orders ship with tracking provided by email. Delivery timelines are shown at checkout for your region.
Can I use it every day?
We recommend 3–5 sessions per week to allow your skin adequate recovery time between sessions. Daily use is generally well tolerated, but consistent 3–5x weekly sessions are how most LED protocols are designed.
