A little time outside feels nice, but before you know it, your skin starts to burn, tan unevenly, or develop stubborn dark spots that refuse to fade. It is also not just about what you see now; UV rays speed up ageing and can cause long-term damage that isn’t immediately obvious. That’s why sunscreen matters!  But with labels full of numbers, plus terms like SPF and PA ratings, figuring out the right product to buy can be confusing. What do they actually mean? And how do you pick the right sunscreen for your skin? Let’s break it all down.

SPF - What It Really Means

SPF (Sun Protection Factor) measures a sunscreen’s ability to protect against UVB rays, which are primarily responsible for sunburn. The number indicates how much longer your skin can be exposed to the sun before burning compared to unprotected skin.

For example-

• SPF 15 blocks about 93% of UVB rays
  

• SPF 30 blocks about 97%
  

• SPF 50 blocks about 98%
  

While higher SPF levels offer slightly more protection, no sunscreen can block 100% of UVB rays. The key is to apply it generously and reapply every two hours, especially when outdoors.

Understanding PA Ratings - Protection Against UVA

While SPF measures UVB protection, PA ratings indicate how well a sunscreen protects against UVA rays, which penetrate deeper into the skin and contribute to premature aging and pigmentation. The PA system, commonly used in Asian sunscreens, is based on the Persistent Pigment Darkening (PPD) test, which measures how long it takes for skin to tan when exposed to UVA.

PA ratings include -

• PA+ – Some UVA protection
  

• PA++ – Moderate UVA protection
  

• PA+++ – High UVA protection
  

• PA++++ – Very high UVA protection
  
  

A broad-spectrum sunscreen protects against both UVA and UVB rays, ensuring comprehensive sun protection.

Choosing the Right Sunscreen

With so many options available, finding the right sunscreen depends on several factors, including your skin type, lifestyle, and environment.

1. Consider Your Skin Type

• Oily or Acne-Prone Skin - Opt for lightweight, oil-free or gel-based formulas labeled as non-comedogenic to prevent clogged pores.
  

• Dry Skin - Choose a sunscreen with added hydrating ingredients like hyaluronic acid or glycerin.
  

• Sensitive Skin - Look for mineral (physical) sunscreens containing zinc oxide or titanium dioxide, which are less likely to cause irritation.
  
  

2. Choose the Right Formula

• Chemical Sunscreens - Absorb UV rays and convert them into heat before they can damage the skin. These tend to be lightweight and blend easily but may not be suitable for sensitive skin.
  

• Mineral (Physical) Sunscreens - Sit on the skin’s surface and reflect UV rays. They are ideal for sensitive skin but can sometimes leave a white cast.
  

• Hybrid Sunscreens - Combine both chemical and mineral filters for a balance of protection and cosmetic elegance.
  
  

3. Water Resistance and Reapplication

If you’re swimming or sweating, choose a water-resistant sunscreen that stays effective for either 40 or 80 minutes before needing reapplication. Even water-resistant formulas should be reapplied every two hours for optimal protection.

Common Sunscreen Myths and Facts

Despite its importance, sunscreen is often misunderstood. Here are a few common myths debunked-

• Myth- Darker skin tones don’t need sunscreen.
  Fact - While melanin provides some natural protection, it does not prevent long-term damage like hyperpigmentation or skin cancer. Everyone benefits from sunscreen.
  

• Myth- Makeup with SPF is enough.
  Fact - SPF in makeup is helpful but rarely applied in the amount needed for full protection. A dedicated sunscreen is still necessary.
  
  Myth- Sunscreen isn’t needed indoors.
  Fact - UVA rays can penetrate windows, so daily sunscreen use is important even when indoors.
