The Ultimate Guide to Daily Sunscreen and UV Protection
The most important step in any morning skincare routine is applying sunscreen every day. It protects your skin from harmful UVA and UVB rays, helps prevent pigmentation and premature ageing, and supports a healthy skin barrier. Daily sunscreen also shields your skin from the combined effects of heat, sunlight, and pollution, making it an essential product you should never skip.
What is SPF?
SPF (Sun Protection Factor) is a rating that shows how well a sunscreen protects your skin from the sun. To understand SPF, it's helpful to know the two types of ultraviolet rays:
- UVA rays: Penetrate deep into the skin and contribute to tanning, pigmentation, premature ageing, and wrinkles. They can even pass through glass.
- UVB rays: Affect the skin's surface and are the main cause of sunburn.
Since both types of UV rays can damage your skin over time, using a broad-spectrum sunscreen is essential.
How SPF Levels Work
SPF measures how effectively a sunscreen protects your skin from UVB rays. SPF 30 blocks about 97% of UVB rays, SPF 50 blocks around 98%, and SPF 70+ blocks close to 99%, providing extra protection during extended sun exposure. For complete protection, choose a sunscreen with PA+++ or PA++++, which indicates strong defence against UVA rays. A combination of high SPF and a high PA rating offers the best daily protection.
Why India's Climate Demands SPF 70
India's UV index runs high for most of the year. Add humidity, pollution, and long commutes under direct sun, and skin here takes a beating that most global sunscreen formulas were never built for.
This is why dermatologists increasingly recommend SPF 70 for daily use in Indian cities:
- Higher UV index across most Indian states through the year.
- Pollution particles that accelerate pigmentation and dullness.
- Humidity that breaks down lower-SPF formulas faster.
- Fitzpatrick III to V skin, which is more prone to visible tanning and post-inflammatory marks.
A daily sunscreen formulated for these exact conditions works harder than one adapted from a cooler, drier climate. This is exactly the gap the Esthe SPF 70+ Daily Sunscreen was built to close. It offers broad-spectrum SPF 70+ PA+++ protection with blue light and pollution defence, using an encapsulated formula that absorbs into the skin in under 60 seconds without any white cast on deeper skin tones.
What to Look for in a Sunscreen
Not every sunscreen suits every skin type. Before you pick one, check these factors:
- Texture: Gel or fluid formulas suit oily and combination skin; cream formulas suit dry skin.
- Finish: Matte finishes control shine, while dewy finishes feel more comfortable on drier skin.
- Fragrance-free: Fragrance-free formulas are generally safer for sensitive and acne-prone skin.
- Non-comedogenic: Choose non-comedogenic formulas to help keep pores clear and reduce the risk of breakouts.
- White cast test: Most sunscreens made for lighter skin tones leave a visible cast on Indian skin.
A daily sunscreen only works if you actually enjoy wearing it. Comfort and finish matter just as much as the SPF number on the bottle.
For daily wear, apply about two finger-lengths of product to your face and neck, ideally 15 minutes before stepping out, and reapply every four hours or after heavy sweating.
