Both of our masks carry the same FDA clearance (K243040), the same four treatment modes, and the same 90-day money-back guarantee. So which one should you actually buy? Here's the honest breakdown — including who should not pay more for the 4D.
The 30-second answer
Choose the AURA 4D ($149.99) if your main concerns are wrinkles, firmness, or deeper skin repair — its fifth wavelength (940nm Deep NIR) and higher LED density are built for exactly that. Choose the AURA Lite ($129.99) if you want the lightest possible daily habit — at 200g it's the one you'll forget you're wearing, and it covers all four core wavelengths.
Side by side
AURA 4D vs AURA Lite, at a glance
Same clearance, same four modes, same guarantee. Here's exactly what stepping up to the 4D gets you.

What stepping up to the 4D actually buys
1. The 940nm Deep NIR wavelength
This is the real difference. Near-infrared light at 850nm already reaches deeper than any visible color, but 940nm penetrates further still — toward the dermis where collagen is made. In the 4D's Dual NIR mode, both wavelengths fire together (a double-tap on the button toggles it), stacking two penetration depths in one session. If anti-aging is your primary goal, this is the feature to pay for. We cover the mechanism in The Science.
2. 48 more LEDs
320 vs 272. More diodes mean more even coverage — fewer dim zones between light points, which matters most around the contours of the nose and jaw.
3. Magnetic cooling pads
A comfort feature that earns its keep in warm climates or post-session: the pads snap on magnetically and take the warmth out of longer treatments.
4. Contoured fit
The 4D's shell follows the face, keeping LEDs at a more consistent distance from the skin. The Lite's flat design trades that for weight savings.
Why the Lite is the right call for many people
Consistency beats specs. Every result in the clinical timelines we've written about assumes you actually use the mask 3–5 times a week — and a 200g mask you can wear while answering email is easier to stay consistent with than anything heavier. The Lite keeps all four core wavelengths, so the Anti-Acne, Glow, and Full Rejuvenation modes work identically. You only give up the Deep NIR layer and the cooling pads.
Who should buy which
Buy the AURA 4D if: fine lines, wrinkles, or loss of firmness are your top concern; you want the strongest anti-aging configuration we make; you run warm and want cooling.
Buy the AURA Lite if: your focus is acne, redness, or overall glow; you travel often (the flat design packs flat); you're new to LED therapy and want the lower entry price.
Either way, you're covered by the same warranty and 90-day money-back guarantee — if you buy the Lite and wish you'd gone 4D, that's what the 90 days are for.
FAQ
Do both masks use the same treatment modes?
Yes — Anti-Aging, Anti-Acne, Glow, and Full Rejuvenation on both. The only mode-level difference is Dual NIR, exclusive to the 4D.
Is the AURA Lite less effective?
For surface concerns — acne, redness, glow — no. Those rely on the blue, amber, and red wavelengths, which both masks share under the same FDA clearance, and both sit well past the ~250 LEDs needed for even full-face coverage (Lite 272, 4D 320). The 4D does pull ahead in two ways: its extra 48 LEDs and contoured shell give slightly more even coverage around the nose and jaw, and — the bigger one — its 940nm Deep NIR reaches deeper for firmness and deep wrinkles. So the 4D does more for anti-aging; for everyday acne and glow, the Lite delivers the same core treatment.
Are both FDA cleared?
Yes, both under K243040.
