Sunscreen Do’s and Don’ts: The Ultimate Guide to Daily Sun Protection
The Personalized Pharmacy Experience You Deserve
Author: Vishnu Patel PharmD. 4/19/2025
Daily sunscreen use isn’t just a summer habit—it’s a year-round investment in your skin’s health. According to the American Academy of Dermatology, wearing sunscreen with at least SPF 30 every day can reduce your risk of skin cancer, sunburn, and premature aging.
But here’s what most people get wrong: how they use it.
In this evidence-backed guide from Rock Ridge Pharmacy, we break down the top do’s and don’ts of sunscreen so you can protect your skin the smart way.
Top Sunscreen Do’s (Dermatologist-Backed)
- 1. Choose a Broad-Spectrum Sunscreen with SPF 30 or Higher
- SPF 30 blocks ~97% of UVB rays. “Broad-spectrum” means it also shields your skin from UVA rays, which cause aging and damage at the cellular level.
- 2. Apply 15–30 Minutes Before Sun Exposure
- Sunscreen takes time to activate. Don’t wait until you’re already outside.
- 3. Use Enough—1 Ounce Per Application
- That’s a full shot glass for your whole body. For your face alone: about a nickel-sized amount.
- 4. Reapply Every 2 Hours, or After Swimming/Sweating
- Water-resistant formulas protect for 40–80 minutes—but no sunscreen lasts all day.
- 5. Cover Commonly Missed Areas
- Don’t forget ears, scalp, back of the neck, tops of feet, hands, and lips (use SPF lip balm).
- 6. Wear It Every Day, Year-Round
- Up to 80% of UV rays still penetrate clouds and windows. Winter? Indoors? Yes, you still need it.
Sunscreen Don’ts That Leave You Unprotected
1. Don’t Rely on SPF Alone - Sun-protective clothing, hats, sunglasses, and shade are all part of the puzzle, especially from 10 AM to 4 PM.
2. Don’t Use Spray Sunscreen in Windy Conditions - You’ll likely miss spots. Instead, spray into your hands, then apply evenly.
3. Don’t Skip Sunscreen If You Have Dark Skin - Even darker skin tones can still burn and develop skin cancer. SPF is for everyone.
4. Don’t Assume Makeup SPF is enough - Makeup with SPF helps, but it wears off. Use an SPF mist or powder for reapplication.
5. Don’t Use Expired Sunscreen - Check the date and store it properly. Expired sunscreen offers weak or no protection.
