Complete Guide to Sunscreen & SPF Ratings for Indian Skin

Sunscreen is an important part of a daily skincare routine. It is designed to help protect exposed skin from ultraviolet (UV) radiation from the sun.

With different SPF ratings, PA ratings, textures and formulations available, choosing a sunscreen can sometimes be confusing. This guide explains common sunscreen terms to help you make a more informed choice.

What Does SPF Mean?

SPF stands for Sun Protection Factor. It indicates the level of protection a sunscreen provides against UVB radiation when the product is used according to its directions.

Common SPF ratings include SPF 30, SPF 40 and SPF 50.

A higher SPF rating provides a higher level of UVB protection, but no sunscreen provides complete protection from UV exposure. Sunscreen should be used according to the directions provided on the product packaging.

What Does the PA Rating Mean?

PA ratings are commonly used to indicate the level of UVA protection offered by a sunscreen.

You may see ratings such as:

• PA+
• PA++
• PA+++
• PA++++

Generally, a greater number of plus signs indicates a higher level of UVA protection according to the applicable rating system.

UVA and UVB

Sunlight contains different forms of ultraviolet radiation.

UVA: UVA radiation can reach deeper layers of the skin and contributes to the effects of long-term sun exposure.

UVB: UVB radiation primarily affects the outer layers of the skin and is associated with sunburn.

Broad-spectrum sunscreens are designed to provide protection against both UVA and UVB exposure.

Choosing an SPF

The appropriate sunscreen can depend on factors such as your daily routine, time spent outdoors, skin type, climate and personal preference.

For everyday use, many people choose broad-spectrum sunscreen with SPF 30 or higher. People who spend longer periods outdoors may prefer a higher SPF product.

Always follow the directions on the individual sunscreen product.

Choosing Sunscreen by Skin Type

Oily or Acne-Prone Skin

People with oily or acne-prone skin may prefer lightweight gel, fluid, oil-free or non-comedogenic sunscreen formulations.

Dry Skin

Cream or lotion-based sunscreens may provide a more comfortable feel for people with dry skin.

Sensitive Skin

People with sensitive skin may prefer simple formulations designed specifically for sensitive skin. Check the ingredient list and product directions before use.

Combination Skin

Lightweight lotion, gel or fluid formulations may be comfortable for combination skin.

Individual product suitability can vary, so choose a formulation according to your skin's needs and the manufacturer's directions.

How Much Sunscreen Should You Apply?

Apply sunscreen evenly to exposed skin according to the quantity and directions stated on the product packaging.

Make sure commonly exposed areas such as the face, neck and ears are adequately covered.

When Should Sunscreen Be Applied?

Follow the directions provided with the sunscreen. Many sunscreen products are intended to be applied before sun exposure.

Reapplication may be necessary, particularly after swimming, heavy sweating, towel drying or extended periods outdoors. Follow the specific reapplication instructions provided by the manufacturer.

Sunscreen and Daily Skincare

Sunscreen can be incorporated into a morning skincare routine after other skincare products, depending on the directions for the products being used.

A simple routine may include:

1. Cleanser
2. Moisturizer, if required
3. Sunscreen

Additional cosmetic products can be applied according to their individual directions.

Additional Sun-Protection Measures

Sunscreen is one part of sun protection. Other measures may include seeking shade, wearing protective clothing, using a hat and limiting prolonged direct sun exposure when practical.
