Why Sunscreen Isn’t Just for the BeachLet’s get this straight:
- UVA rays age the skin by penetrating deep into the dermis, causing wrinkles and long-term damage.
- UVB rays are the ones that burn the surface of your skin.
- Both contribute to skin cancer risk.
UVA rays are sneaky. They pierce through windows, clouds, and pollution. They’re present all year long, from January gloom to August sunshine. So that cloudy Tuesday morning? Yep, your skin still needs protection.
Using actives like retinol or acids at night? Your skin is more sensitive to sunlight the next day. Daily sunscreen isn’t optional. It’s essential to protect your skin from irritation, hyperpigmentation, and damage. Think of SPF as your skin’s bodyguard, especially when you're using powerful nighttime treatments.
Sunscreen isn’t a seasonal product. It’s an everyday shield against invisible harm. Daily use helps prevent fine lines, sagging skin, dark spots, and more serious consequences.
Sunscreen or Moisturizer First?This one causes a lot of confusion, especially for skincare minimalists. Here’s the golden rule:
Moisturizer first, sunscreen last.
Sunscreen needs to sit on top of the skin to form an even protective barrier. Layering it beneath other products can reduce its effectiveness. Think of it like a raincoat — it only works when it’s the outermost layer.
But if your sunscreen also hydrates (like a sunscreen moisturizer), you can simplify. For example, the C Derma Facial Sunscreen SPF50 is a lightweight, hydrating formula that doubles as your day cream.
Pro tip: If you use makeup, apply sunscreen after your skincare but before any foundation or primer.
Which Sunscreen for Which Skin Type?For oily or acne-prone skin:- Choose formulas labeled non-comedogenic (they won’t clog pores)
- Opt for gel-based or fluid textures with mattifying ingredients like niacinamide or silica
- Avoid heavy oils like coconut oil. While it is - indeed - a super power ingredient, it adds to the oily nature of the skin.
For sensitive skin:- Look for mineral or physical sunscreens (with zinc oxide or titanium dioxide)
- Avoid alcohols, added fragrance, and harsh preservatives
- Check for labels like “dermatologically tested” or “for sensitive skin”
For combination skin:- A lightweight, hydrating sunscreen is ideal
- Avoid ultra-matte textures that may dry out cheeks. This could also make your makeup look splotchy or uneven
For darker skin tones:- Choose a formula that doesn’t leave a white cast — many modern mineral SPFs now have invisible finishes
C Derma’s SPF50 checks many of these boxes: suitable for sensitive skin, tested under dermatological control, and with a finish that disappears into your skin.
How to Apply Sunscreen Like You Mean It- Use two full fingers’ length of product for your face and neck
- Apply to hairline, ears, eyelids, neck, chest and hands
- Apply 15 minutes before sun exposure
- Reapply every two hours, or immediately after swimming/sweating
- Don’t forget: windows don’t block UVA
Wearing SPF under makeup? Let it absorb fully, then apply your base. For reapplication, try SPF setting sprays or powders.
A quick note: applying too little sunscreen drastically lowers its protection. A thin layer of SPF 50 may only perform like SPF 15. Quantity matters.
One Daily Habit, Big Long-Term Payoff
Dermatologists estimate that 80% of visible ageing is caused by UV radiation. Let that sink in.
Sunscreen is not just about today’s burn or tan lines — it’s about tomorrow’s fine lines, age spots, and elasticity. It’s skincare’s best-kept (and most obvious) secret.
Think of it as future-proofing your skin. Low effort, high reward. A 30-second habit that pays off for decades.

Because skincare shouldn’t be complicated. Just smart
Can Sunscreen Prevent Tanning?Yes, partially. Sunscreen helps reduce the skin’s response to UVB rays, which are largely responsible for tanning. But it won’t completely prevent melanin production.
This is actually a good thing: you still get your vitamin D and a touch of glow, without the burn or long-term damage. But here’s the catch: tanning is still a sign of skin stress.
So if you want that bronzed look, consider self-tanning products instead of skipping the SPF. Your future skin will thank you.
Can Sunscreen Expire?Absolutely. And using expired sunscreen is a risky move.
Most products have a shelf life of 12 to 24 months after opening. Look for the PAO symbol (a tiny jar icon with “12M” or “24M”).
If your sunscreen has:
- Changed in texture
- Smells off
- Feels unusually oily or runny
... it’s time to toss it.
And no, expired sunscreen won’t harm your skin directly — but it won’t protect you either. That’s harm enough.
What Makes the Best Sunscreen?
The best sunscreen is the one you’ll actually wear every day. But if we’re being specific:
- SPF 30 or higher (SPF 50 for full protection)
- Broad-spectrum coverage (UVA + UVB)
- Non-greasy finish
- Works with your lifestyle and skin type
Look out for:
- "Water-resistant" if you're active
- "Dermatologist-tested" if you’re sensitive
- "Non-comedogenic" if you’re breakout-prone
And avoid:
- Overly fragranced formulas
- Lack of UVA rating (look for a “PA” or “UVA” seal)
C Derma Facial Sunscreen SPF50 delivers all of this — with a light, invisible finish and a vegan, skin-safe formula made in Switzerland.
