Whether it’s a scorching summer or a cloudy winter morning, sunscreen should be a non-negotiable part of your skincare routine. Yet, even with increased awareness, many people continue to make critical sunscreen mistakes that reduce its effectiveness. As Dr. Suruchi Puri, a leading dermatologist in Janakpuri Delhi, points out, “Using sunscreen the wrong way is often just as bad as not using it at all.”
With years of experience as a skin specialist in Janakpuri and recognized as one of the best dermatologist in West Delhi, Dr. Suruchi Puri shares the most common sunscreen mistakes her patients make—and how you can avoid them to protect your skin better.
1. Not Applying Enough Sunscreen
One of the most common mistakes is under-application. Many people use only a small amount of sunscreen, assuming it’s sufficient. According to Dr. Suruchi Puri, “You need at least a nickel-sized dollop for your face and about a shot glass amount for your entire body.”
A skin doctor in Delhi like Dr. Suruchi Puri, emphasizes that using too little sunscreen leaves the skin exposed to harmful UVA and UVB rays, leading to sunburn, premature aging, and even skin cancer.
Don’t be stingy. Apply generously and reapply every 2-3 hours when outdoors.
2. Skipping Sunscreen on Cloudy Days
Many assume they only need sunscreen during bright, sunny days. But up to 80% of UV rays can penetrate clouds. That means even on overcast days, your skin is vulnerable to damage.
As a skin specialist in Delhi, Dr. Puri regularly treats patients with pigmentation and sun-induced skin conditions that could have been avoided with consistent sunscreen use. She advises making sunscreen a daily habit, regardless of the weather.
3. Applying Sunscreen Only Once a Day
Applying sunscreen once in the morning and forgetting about it for the rest of the day is another big no-no. Sunscreen loses its efficacy after a few hours, especially when exposed to sweat, water, or rubbing.
Renowned dermatologist Dr. Suruchi Puri, one of the best in Delhi, advises reapplying sunscreen every two hours—particularly when you’re outdoors, swimming, or sweating. “Even the most expensive sunscreen won’t protect you all day with just one application,” she warns.
4. Relying on Makeup with SPF
Many modern foundations and BB creams contain SPF, which leads people to believe they’ve got sun protection covered. Unfortunately, the amount of SPF in makeup is often insufficient.
As a dermatologist in Janakpuri, Dr. Suruchi Puri highlights, “You’d need to apply an unrealistic amount of foundation to achieve the same protection offered by a dedicated sunscreen.”
Use a broad-spectrum sunscreen under your makeup. Consider SPF in makeup as an added benefit, not a substitute.
5. Not Applying Sunscreen on All Exposed Areas
Sunscreen isn’t just for the face. Many people overlook commonly exposed areas such as the ears, neck, lips, hands, and feet when applying it. These spots are just as susceptible to sun damage and aging.
From her clinic in Janakpuri, Dr. Suruchi Puri often treats uneven skin tone and age spots in these neglected zones. As one of the best dermatologists in Delhi, she stresses that complete coverage is essential for full protection.
6. Applying Sunscreen Right Before Sun Exposure
Sunscreen needs time to activate. Applying it just as you step out isn’t going to offer immediate protection. Dr. Puri, a respected skin doctor in Delhi, recommends applying sunscreen at least 20-30 minutes before stepping outside.
This enables the sunscreen to adhere to your skin and begin creating a protective barrier.
7. Choosing an Unsuitable Sunscreen for Your Skin Type
Not all sunscreens are created equal. Some are better for oily skin, others for dry or sensitive skin. A mismatch can lead to breakouts, clogged pores, or irritation—causing people to stop using sunscreen altogether.
That’s where expert guidance matters. Consulting a skin specialist in Janakpuri like Dr. Suruchi Puri ensures you find a formulation tailored to your skin’s specific needs—whether it’s gel-based, matte finish, tinted, or mineral-based.
8. Not Reapplying After Swimming or Sweating
Even water-resistant sunscreens lose effectiveness after swimming or heavy sweating. Many people wrongly believe that “waterproof” means you’re protected all day.
The best dermatologist in West Delhi, Dr. Suruchi Puri, advises: “Always reapply sunscreen immediately after toweling off, swimming, or intense sweating—even if your sunscreen says water-resistant.”
9. Storing Sunscreen Improperly
Exposure to heat and light can break down the active ingredients in your sunscreen. Leaving it in your car or next to a window reduces its efficacy.
As a reputed dermatologist in Janakpuri Delhi, Dr. Suruchi Puri reminds patients to store sunscreen in a cool, shaded place to maintain its protective power.
10. Using Expired Sunscreen
Yes, sunscreen expires! Using it beyond its shelf life can render it useless—or even harmful if ingredients have broken down. Be sure to check the expiration date and properly dispose of any expired products.
If you’re unsure about which sunscreen suits your skin type, the best dermatologist in Delhi, Dr. Suruchi Puri, can guide you toward tested, dermatologist-approved options.
How to Choose the Right Sunscreen – Expert Tips
Dr. Suruchi Puri recommends looking for these labels on your sunscreen:
- SPF 30 or higher
- Broad-spectrum protection (against both UVA and UVB)
- Water-resistant, if swimming or sweating
- Non-comedogenic, if you have acne-prone skin
