Using the Serum
How do I use it?
Apply a small amount to clean skin morning and evening, following the product label. For external use only; avoid eyes and mucous membranes.
Which size should I choose?
30 ML ($80) - Daily Ritual, ≈ 1-month supply. 50 ML ($100) - Mid-Size, ≈ 2-month supply. 100 ML ($150) - Professional, ≈ 3-month supply.
How should I store it?
Store at room temperature and protect from direct sunlight, following the product label. The supplied archive describes a 12-week cosmetic stability study with a 40°C / <60% RH stress condition; the complete final source report is required before any overall stability or shelf-life conclusion is published.
Safety & Testing
What does the patch-test report say about sensitive skin?
The supplied RIPT report states that 221 subjects completed the study, including 109 with self-perceived sensitive skin. It reports no adverse events and concludes that, under the study conditions, the test article did not demonstrate potential for irritation or sensitization. Individual reactions remain possible; follow the product label.
Are there any warnings?
Do not use if taking prescription anticoagulants (warfarin, heparin, apixaban) without consulting a healthcare professional first. Consult a professional before use if pregnant or breastfeeding. External use only; keep out of reach of children.
What third-party testing record is available?
Three third-party testing reports were supplied: a Repeated Insult Patch Test with 221 completers and no adverse events reported during that study, an OECD 439 in-vitro irritation report with a numerical source discrepancy, and an incomplete 12-week cosmetic stability report.
