For most people, 4–5 sessions a week of 10 minutes each gives the best balance of visible results and skin tolerance. You can use it daily once you've worked up to it. There's no benefit to going past 15 minutes per session — light therapy works on a saturation curve, not a "more is better" curve.

Always on freshly cleansed, bare skin. SPF, makeup, and most actives can either reflect light or break down under it. Apply your serum and moisturizer right after — your skin is in a primed, slightly warmed state and ingredients absorb beautifully.

Yes — but layer it correctly. Use NEUCELLE on bare skin first, then apply vitamin C, peptides, or hydrators. Save retinoids for the opposite end of the day to avoid irritation.

After each session, wipe the inner LEDs with a soft, lint-free cloth lightly dampened with 70% isopropyl alcohol. Never submerge any device in water. Replace the eye strap every 6 months for hygiene.

Yes. Red and near-infrared light at the wavelengths NEUCELLE uses (633 nm and 830 nm) are non-thermal, non-UV, and produce zero photodamage. Sessions are designed in 10-minute blocks well within the safety thresholds set by independent dermatology research.

Red and near-infrared light operate outside the UV spectrum that triggers melanin production. Most customers see improvement, not worsening. If you have active melasma, we still recommend speaking with your dermatologist before starting.

There are no known contraindications, but we recommend pausing facial light therapy during pregnancy and breastfeeding out of an abundance of caution. Your dermatologist or OB-GYN can give you a personalized read.

Yes — in fact, many of our most enthusiastic customers have rosacea. Start with 5-minute sessions twice a week and gradually increase. The 633 nm wavelength is anti-inflammatory and well tolerated.

Most customers notice a "lit-from-within" glow within 7–10 days. Visible firming and softer fine lines typically show by week 4. The clinical sweet spot is 8–12 weeks of consistent use, when collagen remodeling is well underway.

No — the devices work on their own. The Tallow Balm is formulated to lock in post-session results and support the skin barrier. Most customers see better, longer-lasting results when they pair the two. Apply right after a session on clean skin. It's an enhancement, not a requirement.

Yes. Many customers do their NEUCELLE session first (warmed, calm skin), then microcurrent or gua sha after. The two technologies complement each other well.
