India's New Sunscreen Standard (IS 19685:2026), Explained
BIS published IS 19685:2026 for sunscreen cosmetic products, moving India toward in-vivo SPF testing. What it actually means for your sunscreen.
The Bureau of Indian Standards (BIS) has published a dedicated Indian Standard for sunscreen cosmetic products, IS 19685:2026, during 2026. It is one of the more significant changes to sunscreen regulation in India in years, mainly because of how SPF numbers will be verified going forward.
What's actually changing
Until now, most sunscreens sold in India verified their SPF (sun protection factor) claim through in-vitro testing: a lab measurement using synthetic skin models and UV-measuring equipment, then a mathematical projection of the SPF number. IS 19685:2026 moves India toward in-vivo testing, meaning SPF is measured directly on human skin, in line with the international ISO 24444 method. This is widely seen as a more rigorous way to confirm a sunscreen's real-world performance.
What this means for the label you're reading
In practical terms for shoppers, the standard is about how brands must prove their SPF number, not about a new visible label design. It does not change how you should choose or apply sunscreen day to day. Our general sunscreen advice stays the same:
- Choose SPF 30 or higher, PA+++ or higher, for daily Indian sun exposure.
- Apply roughly two finger-lengths of product for the face and neck.
- Reapply every 2–3 hours if you're outdoors, and after swimming or heavy sweating.
Is your current sunscreen affected?
We are not able to say whether any specific product currently on shelves is, or is not, compliant with the new standard; that determination sits with BIS and the manufacturers. If you want to check a specific product's compliance status, the brand or BIS's own resources are the authoritative source, not this article.
Frequently asked questions
What is IS 19685:2026?
A Bureau of Indian Standards specification for sunscreen cosmetic products, published in 2026, which moves SPF verification toward in-vivo (on human skin) testing aligned with the international ISO 24444 method.
Do I need to buy a new sunscreen because of this rule?
No. This is a testing and labelling standard for manufacturers, not a safety recall. Keep using a broad-spectrum SPF 30+ sunscreen daily.
Does a higher SPF number mean better protection?
Up to a point. SPF 30 blocks about 97% of UVB rays and SPF 50 about 98%; the difference is smaller than the numbers suggest. Consistent daily application and reapplication matter more than chasing the highest SPF number.
