In recent years, the importance of sun protection has gained significant recognition. Sunscreens have become an essential part of our daily skincare routine, offering protection against harmful ultraviolet (UV) radiation from the sun. However, with a multitude of sunscreen options available on the market, choosing the right one can be a daunting task.
Let's delve into the different types of sunscreens, their benefits, application techniques, and everything else you need to know to make an informed decision about sun protection.
Understanding Ultraviolet (UV) Radiation
Before we explore sunscreens, it's crucial to understand the nature of UV radiation. The sun emits two types of harmful rays: UVA and UVB. UVA rays penetrate the skin more deeply and contribute to premature ageing, while UVB rays primarily cause sunburn. Overexposure to both types of UV rays increases the risk of skin cancer. Sunscreens work by blocking or absorbing these harmful rays, mitigating their damaging effects.
Types of Sunscreens
Speaking with the editorial team of OnlyMyHealth, Riya Vashist, Makeup Artist and Stylist shares the types, benefits, application techniques, and more to make sun protection easier. Here is what she shared with us.
1. Chemical Sunscreens
Chemical sunscreens contain organic compounds that absorb UV radiation and convert it into heat. These compounds include avobenzone, oxybenzone, octisalate, and more. They are generally easier to apply and offer a wider range of protection against both UVA and UVB rays. However, some chemical filters have come under scrutiny for their potential environmental and health impacts.

2. Physical Sunscreens
Physical sunscreens, also known as mineral or inorganic sunscreens, contain active ingredients like zinc oxide and titanium dioxide. These ingredients work by creating a physical barrier on the skin's surface, reflecting and scattering UV rays away from the skin. Physical sunscreens are generally better tolerated by sensitive skin and are less likely to cause irritation. They provide broad-spectrum protection and are considered safer for the environment.
3. Combination Sunscreens
Combination sunscreens incorporate both chemical and physical filters to provide enhanced protection. By combining the advantages of chemical and physical sunscreens, these products offer broad-spectrum coverage with improved aesthetic qualities, such as reduced white cast or improved texture.
Benefits of Sunscreens
1. Protection against Skin Cancer
The regular use of sunscreens helps reduce the risk of skin cancer by blocking harmful UV radiation.
2. Prevention of Premature Ageing
Sunscreens protect against UVA rays that contribute to premature ageing, including wrinkles, fine lines, and age spots.
3. Minimisation of Sunburn
Sunscreens shield the skin from UVB rays, which cause sunburn and can be painful and damaging.
4. Maintenance of Even Skin Tone
By protecting against UVA-induced pigmentation, sunscreens help maintain a more even skin tone and prevent the formation of dark spots.

Application Techniques
To maximise the benefits of sunscreen, proper application is crucial. Follow these guidelines for effective protection:
1. Choose the Right SPF
Select a broad-spectrum sunscreen with a Sun Protection Factor (SPF) of 30 or higher to ensure adequate protection.
2. Apply Generously
Use a sufficient amount of sunscreen to cover all exposed areas of the body. Experts recommend about two milligrams of sunscreen per square centimetre of skin.
3. Reapply Regularly
Sunscreen should be reapplied every two hours, or more frequently if swimming, sweating, or rubbing the skin with a towel.
4. Don't Forget Neglected Areas
Remember to apply sunscreen to often overlooked areas, such as the ears, back of the neck, and tops of the feet.
Conclusion
In an era when sun protection is paramount, choosing the right sunscreen is essential for maintaining healthy skin and reducing the risk of sun damage and skin cancer. Whether you opt for a chemical, physical, or combination sunscreens, it is important to apply it both indoors and outdoors for the skin you have always dreamt of, shares expert Vashist.
