Frequently Asked Questions
How does the Color Adapting Foundation work?
Protona uses bio-adaptive microsphere technology. When the white formula contacts your skin, the microspheres respond to your body heat and skin's natural pH — releasing pigment at the precise density your skin requires. The result calibrates to your exact tone within 60 seconds. No two people produce the same color. That's not a limitation — that's the point.
What skin tones does it work for?
All of them. Protona is developed and tested across all six Fitzpatrick skin types — from the fairest complexions to the deepest, including the dark and deep brown tones most color-adapting foundations quietly fail on. No ashy finish. No orange cast. No undertone left behind.
Does it contain SPF?
Yes. Every application contains SPF 50 broad-spectrum protection — UVA and UVB. That's more than double the SPF of our closest competitors. For daily incidental sun exposure, Protona replaces your separate SPF step entirely. For extended outdoor exposure, layer a dedicated sunscreen underneath.
How long does it last?
Up to 12 hours of wear without oxidation or color shift. The formula bonds with your skin over the first 10–15 minutes and stays transfer-resistant throughout the day. What you see at 8am is what you wear at 8pm.
What is your return policy?
30-day money back guarantee. If Protona doesn't perfectly match your skin tone, or you're unsatisfied for any reason, contact us within 30 days for a full refund. Just email support@protonalabs.com.
Do you offer free shipping?
Yes. Free standard shipping on all US orders over $39. International shipping also available.
How do I apply it?
- Start with clean skin. Moisturizer optional — Protona works on both
- Dispense 1–2 pumps onto fingertips or a brush.
- Press into skin using upward strokes. The formula will appear white.
- Wait 60 seconds. Watch your exact shade emerge.
- Build coverage as desired. No blending forever required.
Is it cruelty-free?
Yes. Protona is 100% cruelty-free and never tested on animals. Also paraben-free, fragrance-free, vegan, and dermatologist-recommended.
Can I use it with other skincare products?
Yes. Apply your regular moisturizer first, allow 1–2 minutes to absorb, then apply Protona. The pH-adaptive technology works effectively over most skincare products. Avoid applying directly over thick occlusive balms or heavy oils, as these can interfere with the pH-detection process.
How long does one bottle last?
One 40g bottle lasts approximately 60–90 days with daily use, based on 1–2 pumps per application. Light coverage users typically get 90 days. Full coverage users closer to 60 days.
