The certificate documents Primary Skin Irritation Testing on human participants after Ethics Committee approval and under dermatologist supervision.

Important Points to Know Before Use
1. Apply a thin, even layer on clean, dry skin before bed; it dries to a veil in 15-20 minutes and peels off in the morning.
2. Avoid the eye area and lips. Do not apply over broken or irritated skin.
3. Individual skin responses may vary, so a personal patch test is recommended before first use.
4. In case of irritation, rashes or allergy, discontinue use and consult a specialist. For external use only.
Frequently Asked Questions
Q: Is Dr. Sheth's Collagen & Vitamin C Overnight Moisture Wrapping Mask dermatologically tested?
A: Yes. The certificate records Primary Skin Irritation Testing on human participants at Cliantha Research under Study Protocol No. C3B06080, Sub Study No. C3B06080-HON-J, and reports the product as Dermatologically Safe for use and Non-Irritant.

A: It documents the product tested, the type of dermatological safety assessment performed, the study protocol details and the reported result. The original certificate and full transcription are published on this page.
Q: Who supervised the patch testing?
A: The certificate is signed by Dr. Bhagirath Patel, M.D., DVL (Dermatologist and Principal Investigator) and Dr. Parth Joshi (Investigator) of Cliantha Research, after Ethics Committee approval.
Q: Which standards were followed during the study?
A: The certificate states that the clinical study was conducted according to Bureau of Indian Standards guidelines, including IS 4011 (2018) PCD 19 for cosmetics (third revision).
Q: Is an overnight mask that stays on for 6-8 hours safe for sensitive skin?
A: Because it stays on the face far longer than a rinse-off product, skin tolerance matters more than usual - which is why it was patch tested. Cliantha Research certified it Non-Irritant on human participants. Sensitive skin can still react to any product, so do the personal patch test below first.
Q: Is this the same product that has an NABL lab test report?
A: Yes. The mask also has a Sigma Test & Research Centre report covering microbiology and physico-chemical parameters, published on its own NABL lab test report page.
Q: Should I still patch test the product before use?
A: Yes. Certificate results reflect testing on a sample group under clinical conditions, and individual skin can react differently. Apply a small amount on the inner arm, wait 24 hours, and check for any reaction before regular use.
