Why Sunscreen Matters More Than Any Other Product

Every dermatologist agrees: the most effective anti-ageing product is sunscreen, not retinol, not Vitamin C, not peptides. UV radiation causes up to 80% of visible skin ageing. No serum can undo damage that you could have prevented with daily SPF.

UVA vs. UVB:

• UVB (290–320nm) — causes sunburn, damages the epidermis. SPF measures UVB protection.
• UVA (320–400nm) — penetrates deeper, causes photoageing, wrinkles, hyperpigmentation. Look for the UVA circle symbol or PA++++ rating.
• Blue light (HEV) — emerging research suggests high-energy visible light contributes to hyperpigmentation in darker skin tones.

The PPD Rating You Should Know:

PPD (Persistent Pigment Darkening) measures UVA protection. The EU standard requires PPD ≥ 1/3 of the SPF number. La Roche-Posay's UVMune 400 achieves PPD 46 — among the highest available.

Chemical vs. Mineral Sunscreens

| Feature | Chemical | Mineral (Physical) | |---------|----------|-------------------| | Active filters | Organic molecules absorb UV | Zinc oxide / titanium dioxide reflect & absorb UV | | White cast | None (usually) | Often visible, especially on darker skin | | Texture | Lightweight, cosmetically elegant | Can feel heavy or chalky | | Best for | Most skin types | Very sensitive skin, babies, post-treatment | | Reef-safe | Depends on filters | Yes |

UK recommendation: Chemical sunscreens offer superior cosmetic elegance. If you've avoided SPF because of texture or white cast, modern chemical filters (Mexoryl, Tinosorb) are game-changers.

How Much Sunscreen to Apply

The SPF rating assumes 2mg of product per cm² of skin. For the face and neck, that's approximately:

• Two finger lengths (index and middle finger) of sunscreen
• 1/4 teaspoon (exact measurement)

Most people apply only 25–50% of the required amount, meaning their "SPF50" sunscreen is actually providing SPF15–20 protection.

Tip: Apply in two layers — half, wait 60 seconds, then the second half. This ensures even coverage.

FAQ — Sunscreens

Do I need sunscreen indoors?

If you sit within 1 metre of a window, yes. UVA penetrates glass. If you're deep indoors away from windows, incidental exposure is minimal.

Can I use last year's sunscreen?

Check the PAO (Period After Opening) symbol on the packaging. Most sunscreens are stable for 12 months after opening. If separated, changed colour, or smells different — discard.

Is SPF50 enough, or do I need SPF100?

SPF50 blocks 98% of UVB. SPF100 blocks 99%. The 1% difference is negligible in real-world conditions. SPF50+ is sufficient when applied correctly (and reapplied every 2 hours of sun exposure).

Does darker skin need sunscreen?

Absolutely. While melanin provides some natural protection (equivalent to SPF13–15), it's insufficient. Darker skin is prone to hyperpigmentation from even mild UV exposure. Sunscreen prevents dark spots from worsening.

Can I skip moisturiser and just use sunscreen?

If your sunscreen contains hydrating ingredients (glycerin, niacinamide), you can — especially if you have oily skin. For dry skin, apply moisturiser first, let absorb for 5 minutes, then apply sunscreen.
