If there’s one skincare product dermatologists universally agree on, it’s sunscreen. Sun protection is the single most effective way to prevent premature ageing, hyperpigmentation, and skin damage. Yet it remains the most commonly skipped step in people’s routines.
What UV Rays Do to Your Skin
The sun emits two types of harmful ultraviolet radiation:
- UVA Rays: Penetrate deep into the dermis, breaking down collagen and elastin. Responsible for photoageing, wrinkles, and sagging
- UVB Rays: Affect the outer layers of skin, causing sunburn and contributing to skin cancer risk
Both types of UV radiation stimulate melanin production, leading to dark spots, uneven skin tone, and hyperpigmentation over time.
Why Medical-Grade SPF Matters
Not all sunscreens are created equal. Medical-grade formulations from brands like Obagi offer superior protection through:
- Broad-spectrum UVA and UVB coverage
- Higher concentrations of active sun filters
- Elegant formulations that layer well under makeup
- Additional antioxidant protection
- Non-comedogenic formulas suitable for all skin types
How to Use SPF Correctly
- Apply generously as the last step of your morning skincare routine
- Use at least a two-finger length amount for your face and neck
- Reapply every 2 hours when outdoors or after swimming/sweating
- Don’t forget often-missed areas: ears, neck, backs of hands
- Use SPF even on cloudy days—up to 80% of UV rays penetrate clouds
SPF and Active Skincare
If you’re using medical-grade actives like retinol, vitamin C, or AHAs, SPF becomes even more critical. These ingredients make your skin more photosensitive, meaning unprotected sun exposure can undo your results and cause further damage.
