Dermatologist-Tested Claim Verification and Testing for Facial Oil

A California-based skincare brand is launching a natural facial oil product and is seeking professional “Dermatologist-Tested” validation, along with standard cosmetic safety testing. They are specifically interested in the following services:

• Human patch testing under dermatologist supervision to support a “Dermatologist Tested” claim
• Microbiology testing (USP or equivalent)
• Preservative efficacy/challenge testing (if applicable)
• Stability and shelf-life testing

Could you please provide the following information:

1. A quote for these services (including package options if available)
2. Typical turnaround times
3. Sample size requirements for submission
4. Whether your lab provides dermatology oversight directly, or if you partner with board-certified dermatologists

As a small business, they especially appreciate cost-effective testing solutions. Please reach out if you need our ingredient list, Safety Data Sheets, or any additional details to prepare an estimate.

Thank you in advance for your guidance
