Have you ever felt overwhelmed by the sheer number of sunscreens available on the market? Terms like SPF, PA+++, broad-spectrum, and water resistance can be confusing. But don’t worry! Our celebrity cosmetic dermatologist, with 17+ years of experience, explains everything you need to know about sunscreen—its importance, types, how to choose the right one for your skin type, and the correct way to apply it.
1. Why Do You Need Sunscreen?
While the sun is essential for life, its ultraviolet (UV) rays can cause severe skin damage when exposed for long periods. UV radiation is responsible for:
- Sunburn
- Premature aging (wrinkles, fine lines)
- Hyperpigmentation and dark spots
- Skin cancer
Sunscreens are designed to protect your skin from these harmful effects by acting as a barrier against UV rays.
2. Types of Sunscreens
2.1 Physical (Mineral) Sunscreen
- Contains minerals like zinc oxide and titanium dioxide
- Forms a protective layer on the skin that reflects UV rays
- Suitable for children and sensitive skin
- Tends to leave a white cast and has a thicker texture
- Can cause a slight stinging sensation on some skin types
2.2 Chemical Sunscreen
- Contains sun filters like Oxybenzone, Octocrylene, Avobenzone
- Absorbs UV rays and converts them into heat
- Has a lighter consistency, making it easier to blend
- More suitable for all skin types, especially oily skin
- Does not leave a white cast
3. How to Choose Sunscreen According to Your Skin Type
3.1 Understanding SPF
SPF (Sun Protection Factor) determines how much UVB radiation a sunscreen can block:
- SPF 15 – Blocks 93% of UVB rays
- SPF 30 – Blocks 97% of UVB rays
- SPF 50 – Blocks 98% of UVB rays
The American Academy of Dermatology recommends using at least SPF 30.
3.2 PA+++ Rating
PA rating measures protection against UVA rays:
- PA+ : Some UVA protection
- PA++ : Moderate UVA protection
- PA+++ : High UVA protection
- PA++++ : Very high UVA protection
3.3 Broad-Spectrum Protection
Always choose a broad-spectrum sunscreen that protects against both UVA and UVB rays.
3.4 Choosing Based on Skin Type
- Dry skin – Look for hydrating ingredients like ceramides and hyaluronic acid
- Oily skin – Use gel-based or water-based sunscreens that are non-comedogenic
- Sensitive skin – Opt for mineral sunscreens with zinc oxide or titanium dioxide
- Outdoor activities – Choose water-resistant sunscreen
3.5 Different Formulations
- Gels – Best for oily skin
- Creams – Ideal for dry skin
- Sprays – Useful for hard-to-reach areas
- Sticks – Convenient for on-the-go application
- Lotions – Lightweight and easy to spread
4. How to Apply Sunscreen Correctly
- Apply a generous amount of sunscreen (at least a pea-sized amount for the face).
- Spread evenly on all exposed areas – face, neck, ears, arms, hands, feet.
- Reapply every 2 hours, especially after sweating or swimming.
- Apply sunscreen even indoors, as blue light from screens can also damage the skin.
- Use sunscreen in all weather conditions, whether it’s sunny, cloudy, or raining.
