We’ve all heard the golden skincare rule: never skip sunscreen. And many of us don’t. Yet, sun damage, pigmentation, and premature aging still creep in. Why? Because using sunscreen is not the same as using the right sunscreen.
If your sunscreen feels sticky, clogs pores, leaves a ghostly white cast, or still lets you tan after a day outdoors—chances are, you’ve been using the wrong one.
Let’s break down why this happens, how to identify a sunscreen that actually protects your skin, and the key things to look for before your next purchase.

1. SPF ≠ Full Protection: Understanding What SPF Really Means
Most people assume SPF is everything. The higher the number, the better the sunscreen, right?
Not entirely. SPF only measures protection against UV (ultraviolet) rays, the ones that cause sunburn.
It doesn’t protect you from UVA rays, which penetrate deeper and are responsible for premature aging and long-term skin damage.
What to Look for Instead?
- A broad-spectrum sunscreen — this protects against both UVA and UVB.
- At least SPF 30 for daily use (SPF 50 if you're out in direct sun for long).
- Look for PA+++ ratings on Asian sunscreens—this indicates high UVA protection.

2. You're Not Using Enough (Yes, That Matters)
Using a pea-sized amount for your whole face and a squirt for your entire body? That’s far too little.
Dermatologist tip: You need about half a teaspoon for the face and neck alone and a shot glass full (around 30ml) for the body.
Using less than recommended drastically reduces the effectiveness, even if your SPF is 50.
3. Chemical vs Mineral: Know the Difference
There are two main types of sunscreens, and choosing the right one depends on your skin type.
Chemical Sunscreens (e.g. avobenzone, oxybenzone):
- Absorb into the skin and convert UV rays into heat.
- Lightweight and often invisible.
- May cause irritation for sensitive or acne-prone skin.
Mineral/Physical Sunscreens (e.g. zinc oxide, titanium dioxide):
- Sit on top of the skin and reflect UV rays.
- Better for sensitive skin.
- May leave a white cast unless tinted or micronized.
What to Do?
- Oily/acne-prone skin? Go for gel-based chemical sunscreen labeled non-comedogenic.
- Sensitive skin or kids? Stick to mineral sunscreen with zinc oxide.
- For daily wear under makeup? Try hybrid formulas with a matte or invisible finish.
4. That Fancy "Waterproof" Label Might Be Misleading
Sunscreens labeled as waterproof or sweatproof sound like a dream—but there's a catch.
Reality Check: No sunscreen is truly waterproof. The FDA doesn’t even allow that term anymore.
What you’ll see now is:
- Water-resistant (40 minutes)
- Water-resistant (80 minutes)
That means it holds up for that duration while swimming or sweating. After that? Reapply.
What to Look for Instead?
- Always reapply every 2 hours if you’re outdoors.
- Reapply immediately after swimming, toweling, or heavy sweating—even if it’s water-resistant.
5. Skipping Sunscreen Indoors or on Cloudy Days? Still a Mistake
Think you’re safe indoors or on a rainy day? Think again. UVA rays can penetrate glass—meaning your windows or car windshield don’t block them. Up to 80% of UV rays can pass through clouds. So if you sit by a window at work or drive daily, you’re still getting sun damage.
Fix it: Make sunscreen a daily part of your AM routine, rain or shine.
6. Sunscreens with Added Skincare Can Be a Bonus (But Not a Replacement)
Sunscreens now come with added benefits: niacinamide, vitamin C, hyaluronic acid, etc.
That’s a great bonus but don’t confuse it with actual skincare treatment. Sunscreen should always protect first.
Good Combo Options:
- Niacinamide: Reduces pigmentation and soothes skin.
- Vitamin C: Antioxidant that boosts sun protection.
- Matte finish: Helps control oil for long hours.
Look for multifunctional sunscreens only after confirming the basic requirements—broad spectrum, high SPF, and skin compatibility.
7. Spray Sunscreens, Makeup SPFs & Cushions: Are They Enough?
Here’s the short answer: no.
Makeup or cushion foundations with SPF aren’t enough by themselves. Most people apply far too little for effective protection. Spray sunscreens? Great for touch-ups, but not ideal as a base layer.
Use These Only:
- For top-ups every few hours.
- Over actual sunscreen, not instead of it.
- When reapplying sunscreen over makeup (powder SPF can help too).

Sunscreen for Every Season and Situation
Sunscreen isn’t just for beach days or summer hikes. Different situations demand different sunscreen strategies. Here’s how to tailor your sun protection throughout the year:
1. Summer Outdoor Events (Beach, Picnics, Treks, Festivals)
This is when UV levels peak—and so does sun exposure.
What to Use?
- SPF 50+ broad-spectrum
- Water-resistant for sweat/swimming
- Reapply every 2 hours
- Wear a hat, sunglasses, and UPF-rated clothing
2. Office and Indoor Days (Window Exposure Matters)
You may not realize it, but UVA rays penetrate through glass. That 9–5 by the window? It adds up.
What to Use?
- Lightweight, non-greasy sunscreen
- SPF 30–50 with PA+++
- Works well under makeup
3. Monsoon & Cloudy Days
Don’t skip sunscreen just because the sun isn’t visible. UV rays are still active.
What to Use?
- Waterproof sunscreen to handle humidity
- SPF 30+
- Matte-finish formulas to combat sweat
4. Winter Travel (Snow Holidays or Mountains)
Snow reflects up to 80% of UV rays—meaning you’re double-exposed.
What to Use?
- SPF 50+
- Cream-based sunscreen to fight dryness
- Lip balm with SPF
5. Everyday Errands & School Runs
Even 10 minutes in the sun adds up. Quick outings still need protection.
What to Use?
- Tinted or stick sunscreen for quick application
- Mineral sunscreen for kids
- Travel-size for on-the-go use
6. Special Occasions (Weddings, Photoshoots, Makeup Days)
You want sun protection that plays well with makeup.
What to Use?
- Invisible or gel-based sunscreen
- SPF-infused setting sprays or powders
- Look for a primer-like finish

Final Word
You can buy the most expensive sunscreen out there, but if it sits unused because it’s too greasy, too white, or too perfumed—it won’t protect you.
Find a formula that fits your lifestyle, skin type, and daily routine. Because in the battle against UV damage, consistency beats perfection.
