SPF in India: Why UV Index Changes Everything

A UV Index of 8 in Mumbai is not the same as UV 8 in London. Here's what you need to know.

Walk into any pharmacy and you'll find SPF 15, SPF 30, SPF 50. Most Indians grab SPF 30 because it sounds "enough." It isn't — especially during peak summer months in cities like Mumbai, Chennai, or Hyderabad.

What UV Index Actually Means

The UV Index is a 0–11+ scale measuring how quickly unprotected skin can burn. In most Indian cities between April and September, UV Index hits 9–11 (extreme) by 10 AM. At UV 10, unprotected skin begins to burn in as little as 12 minutes.

SPF Breakdown: What to Use When

UV 0–2 (Low): SPF 15 is fine
UV 3–5 (Moderate): SPF 30 minimum
UV 6–7 (High): SPF 50 required
UV 8–10 (Very High): SPF 50+ and reapply every 90 min
UV 11+ (Extreme): SPF 50+, cover up, avoid direct sun

Let CommuteGlow do the math

Every time you open the Skincare Advisor, it checks live UV index for your city and recommends the exact SPF level for today — not a generic one-size-fits-all suggestion.

The 2-Hour Rule

SPF doesn't last all day. It degrades with sweat, sebum and time. If your commute or outdoor exposure exceeds 2 hours, a midday reapplication is not optional — it's essential. A UV-protective powder or spray SPF makes this easy without ruining your makeup.

CommuteGlow sends you a mid-day SPF reminder on high UV days automatically when you have notifications enabled.
