Frequently Asked Questions
Everything you need to know about Protocole® and your Dosologie experience.
What is Protocole®?
Protocole® is your entire skincare routine compressed into pre-dosed capsule blisters. Each blister contains the exact actives you need — cleanser, serum, moisturizer, SPF — in the right order and the right dosage. No guessing, no waste, no 7 bottles on your counter.
How do I use it?
Open one blister. Apply each capsule in order, from 1 to the last. That's it — your full routine in under 2 minutes. Each capsule is labeled so you always know the correct layering sequence.
What's the difference between the 7-day, 14-day, and 28-day supplies?
Same formula, different duration. The 7-day ($65) is perfect to try Protocole® for the first time. The 14-day ($90) covers two weeks. The 28-day ($130, or $110.50/mo with a subscription) is your full monthly supply and the best value per day.
Is Protocole® suitable for sensitive skin?
Yes. Our formulations are dermatologist-tested and designed to be gentle across all skin types, including sensitive skin. The pre-dosed format also eliminates the risk of over-applying actives — one of the most common causes of irritation.
What active ingredients are inside?
Each Protocole® blister contains pharmaceutical-grade actives including hyaluronic acid, niacinamide, vitamin C, peptides, and broad-spectrum SPF — pre-dosed at clinical concentrations. The sealed format keeps every active fresh until the moment you use it, unlike open bottles that oxidize over weeks.
Why capsules instead of regular bottles?
Three reasons. First, freshness — sealed single-dose capsules don't oxidize like a bottle of vitamin C that sits open for months. Second, precision — every dose is measured at the exact concentration that clinical studies use. Third, simplicity — no measuring, no layering guesswork, no counter full of products.
Can Protocole® really replace my entire routine?
Yes. Protocole® replaces your cleanser, toner, serum, eye cream, moisturizer, and SPF. Each step is built into the blister in the correct order and at the right dose. You don't need to add anything else.
How does it compare to buying separate products?
A typical multi-step routine (cleanser, toner, vitamin C serum, eye cream, moisturizer, primer, SPF, night treatment) costs around $236/month at Sephora or Ulta. Protocole® subscription is $110.50/month — with better dosing, fresher actives, and zero guesswork.
Is it good for travel?
Protocole® was practically designed for it. Flat blister packs fit in any bag, comply with TSA liquid rules, and replace an entire bag of bottles. No spills, no weight, no decisions about what to bring.
Are the actives at clinical-grade concentrations?
Yes. Every active in Protocole® is dosed at the concentration used in published clinical studies — not the diluted amounts you typically find in mass-market products. Pre-dosing removes the guesswork and ensures consistency across every single use.
Why does sealed packaging matter for actives like vitamin C?
Vitamin C (L-ascorbic acid) starts degrading within days of exposure to air and light. A standard bottle loses potency over weeks of daily opening. Each Protocole® capsule is sealed individually, so the actives are as potent on day 28 as they are on day 1.
Is Protocole® tested on animals?
No. Dosologie is cruelty-free. We do not test on animals at any stage of development or production, and we do not work with suppliers who do.
Where is Protocole® formulated and manufactured?
Protocole® is formulated and manufactured in France under pharmaceutical-grade quality standards. Every batch is tested before packaging to ensure purity and potency.

Can I skip or pause my subscription?
Yes. You can skip a delivery, pause, or change the frequency from your account dashboard at any time. No commitment, no penalties.
How do I cancel my subscription?

How much does shipping cost?

How long does delivery take?
