The Role of Sunscreen in Skincare
Introduction
When it comes to skincare, many people focus on products that moisturise, brighten, or fight acne. However, there’s one product that stands above the rest in terms of protection, prevention, and long-term skin health—sunscreen. Often underrated or forgotten, sunscreen is a cornerstone of any effective skincare routine. It doesn’t just prevent sunburns—it protects against premature ageing, hyper pigmentation, and even life-threatening skin cancers.
In this article, we will explore who needs sunscreen, what it does for the skin, how it functions, and why incorporating it into your daily skincare routine is essential for maintaining healthy and youthful skin.
What Is Sunscreen?
Sunscreen, also called sunblock or sun cream, is a topical product designed to protect the skin from the sun's ultraviolet (UV) rays. It comes in various forms including creams, gels, sprays, and sticks. Sunscreens are formulated with ingredients that either:
-
Physically block or reflect UV rays (e.g., zinc oxide, titanium dioxide), or
-
Chemically absorb and neutralise UV radiation before it damages the skin (e.g., avobenzone, oxygenation).
The level of protection is indicated by the Sun Protection Factor (SPF). The higher the SPF, the more protection it offers against UVB rays, which cause sunburns. However, effective sunscreen should also offer broad-spectrum protection to shield the skin from both UVA and UVB rays.
Why Sunscreen Matters in Skincare
1. Prevents Premature Ageing (Photographing)
Long-term sun exposure is one of the main contributors to visible signs of ageing. UV rays break down collagen and lasting, the proteins that keep skin firm and elastic.
Without sunscreen, your skin may develop:
-
Fine lines and wrinkles
-
Sagging skin
-
Uneven texture
-
Dark spots or age spots
Consistent use of sunscreen protects your skin’s structure and helps you age gracefully, with fewer visible signs of sun damage.
2. Reduces the Risk of Skin Cancer
Skin cancer is one of the most common types of cancer worldwide, and UV exposure is its primary cause. Sunscreen plays a vital role in blocking UV radiation that can damage DNA in skin cells, which may eventually lead to:
-
Basal cell carcinoma
-
Squamous cell carcinoma
-
Melanoma (the most dangerous and potentially deadly form)
Wearing sunscreen daily—regardless of weather—can significantly lower your risk of developing skin cancer over your lifetime.
3. Prevents Sunburn
A sunburn is a clear indication of skin cell damage from UVB rays. The redness, pain, peeling, and inflammation not only harm the skin but also increase the risk of complications over time.
Sunscreen with SPF 30 or higher:
-
Reduces inflammation
-
Minimises discomfort
-
Prevents skin peeling and blistering
Sunburns also damage the skin barrier, making it more prone to infections and sensitivity.
4. Controls Hyper pigmentation and Uneven Skin Tone
UV rays trigger excess melanin production, which can lead to:
-
Dark spots
-
Freckles
-
Melanoma
-
Post-inflammatory hyper pigmentation (after acne)
People with darker skin tones are particularly prone to hyper pigmentation, and sunscreen is essential in preventing these issues from worsening.
Regular use of sunscreen helps maintain a smooth, even-toned complexion by minimising melanin overproduction and preventing new dark spots from forming.
Who Needs Sunscreen?
The answer is simple: everyone.
-
All skin tones need sunscreen. Darker skin may have more melanin, but it is not immune to sun damage or skin cancer.
-
All genders need it—not just women who wear makeup or beauty products.
-
Children and babies (over 6 months) should also use sunscreen when outdoors.
-
People who stay indoors still need sunscreen because UVA rays penetrate windows and glass.
-
During all seasons—not just in summer. UV radiation is present all year round, even on cloudy or rainy days.
Types of Sunscreen: Physical vs. Chemical
1. Physical (Mineral) Sunscreen
-
Contains zinc oxide or titanium dioxide
-
Sits on top of the skin and reflects UV rays
-
Ideal for sensitive skin types
-
Begins working immediately upon application
-
Less likely to cause irritation or allergic reactions
2. Chemical Sunscreen
-
Contains ingredients like avobenzone, oxygenation, indoctrinate
-
Absorbs into the skin and neutralises UV rays
-
Often lighter and more transparent on the skin
-
Requires 15–30 minutes before sun exposure
-
May not suit very sensitive skin
Choosing the right sunscreen depends on your skin type, personal preferences, and potential sensitivities.
How to Use Sunscreen Correctly
To fully benefit from sunscreen, it must be used properly:
-
Apply generously: Use at least a nickel-sized amount for the face and a shot glass full for the body.
-
Don’t forget key areas: Ears, neck, eyelids, lips, and the back of the hands.
-
Apply before sun exposure: 15 to 30 minutes before going outdoors.
-
Reapply regularly: Every 2 hours, and immediately after sweating, swimming, or towel drying.
-
Layer correctly: Sunscreen should be the last step of your skincare routine but before makeup.
Make sunscreen a non-negotiable part of your daily skincare, not just an occasional add-on.
How Sunscreen Complements Other Skincare Products
Sunscreen works hand-in-hand with other skincare products to:
-
Protect the results of serums and treatments, such as Vitamin C or retinal
-
Prevent further damage after skin resurfacing or exfoliation
-
Enhance barrier repair and reduce inflammation
Using powerful active ingredients without sun protection can worsen skin issues and make your skin more sensitive to UV rays.
Common Myths About Sunscreen
-
“I don’t need sunscreen indoors.”
-
False. UVA rays penetrate through windows and still harm your skin.
-
-
“Dark skin doesn’t burn.”
-
False. Dark skin can still burn, age, and develop skin cancer.
-
-
“Sunscreen blocks Vitamin D.”
-
Minimal sun exposure is enough to produce Vitamin D; sunscreen doesn’t significantly block absorption.
-
-
“I only need sunscreen in summer.”
-
UV rays are present year-round, even in winter or on cloudy days.
-
-
“My makeup has SPF, so I’m protected.”
-
Makeup with SPF offers limited protection and must be supplemented with dedicated sunscreen.
-
