Sunscreen labels combine regulatory and testing language with consumer-facing claims. For a factual comparison, record exactly what is stated and avoid converting a label into a personal-use recommendation.
SPF and UVA information are different fields
ISO publishes test methods for determining labelled sun protection metrics. ISO 24444 covers in-vivo determination of SPF, while ISO 24443 covers in-vitro characterization of UVA protection. A product may also use a PA grade or other UVA notation depending on its market and testing framework.
Record the exact wording
| Field | Example of what to record |
|---|---|
| SPF | SPF 30, SPF 50, SPF 50+ |
| UVA | PA rating, UVA-PF or other stated UVA information |
| Water resistance | Exact duration or wording if stated |
| Quantity | 50 g, 50 ml, 80 g, etc. |
| Format | Cream, gel, fluid, stick, spray |
Do not assume two SPF 50 products are identical
The same labelled SPF does not tell you that the base formula, UVA protection, texture, water-resistance claim, packaging or quantity is the same. A useful comparison table keeps each of those as a separate row.
Calculate price per 10 g or 10 ml
Because sunscreen packs can be relatively small, a per-10-unit measure is easy to read. If a 50 g pack costs ₹699, the price per 10 g is ₹139.80. Keep grams and millilitres separate unless a manufacturer provides a conversion.
“Tested”, “clinically tested”, “SPF tested”, “UVA tested” and “water resistant” are not interchangeable phrases. Record the exact statement and, when a brand publishes a test method or report, link to it rather than paraphrasing it more strongly.
Frequently asked questions
Is SPF the same as UVA protection?
No. SPF and UVA protection are distinct measurements and are covered by different test approaches.
Can two SPF 50 sunscreens have different UVA information?
Yes. The SPF label alone does not establish identical UVA performance or identical labelling.
Should price be compared per pack?
Price per pack is useful, but price per 10 g or 10 ml makes differently sized packs easier to compare.
Sources and reference framework
DermaQA uses primary or official references where practical. Product formulas and labels can change, so the current pack and manufacturer page remain the most direct references for a specific product.
