You can buy hundreds of dollars worth of serums and visit your aesthetician every week, but without SPF, all of that is money down the drain.
In my esthetics training, sun protection was one of the very first and most critical principles we were taught. Not because it’s a trend, but because no serum, treatment, or professional procedure can undo the continuous damage caused by UV rays. I see this constantly in my practice with clients: skin that looks tired, dull, or uneven almost always traces back to inconsistent SPF use, not a lack of good skincare products.
Up to 90% of wrinkles, sagging, and dark spots are the result of photoaging (skin damage caused by UV rays). UVA rays penetrate through clouds and windows, breaking down your collagen structure while you simply sit near a window or grab a coffee. Sunscreen isn’t just a beach essential—it’s the most important anti-aging product in your skincare routine.

3 Golden Rules of Sun Protection (And Why It Fails Without
Them)
– The Two-Finger Rule: Apply two full strips of sunscreen onto your index and middle
fingers—this is the exact dosage needed for your face and neck. Using less drastically reduces protection.
– Proper Cleansing: Sunscreen filters are designed to stay locked onto the skin. Always double-cleanse in the evening (cleansing oil/balm followed by a water-based cleanser) to avoid clogged pores.
– Broad Spectrum (PA++++ / UVA Symbol): Look for these labels to ensure your skin is protected not just from sunburns (UVB), but also from deep photoaging and cell
damage (UVA).
