With the naturally high UV index here in New Zealand, sunscreen isn’t just a summer essential - it’s a year-round must-have. Protecting your skin from harmful UV rays is one of the most important steps in any skincare routine. But with so many choices, how do you decide between physical and chemical sunscreens? Let’s break down the differences and help you choose the best option for your skin type and lifestyle. Why Sunscreen is Essential in New Zealand New Zealand has one of the highest UV indexes in the world, meaning the sun’s rays are particularly strong and harmful. Overexposure to UV radiation can lead to a variety of skin issues, including accelerated ageing, pigmentation, fine lines, and an increased risk of skin cancer. UVA rays penetrate deep into the skin, breaking down collagen and elastin, which results in wrinkles and sagging skin. Meanwhile, UVB rays can cause sunburn and directly damage the DNA in your skin cells, leading to pigmentation and uneven skin tone. UV exposure also generates free radicals - unstable molecules that damage skin cells and lead to oxidative stress. This not only accelerates the ageing process but can also compromise the effectiveness of your skincare routine. For those who invest in professional treatments, daily sunscreen use is crucial for maintaining the results and protecting the skin from the damaging effects of the sun. Without daily SPF, you’re leaving your skin vulnerable to the very damage you're working hard to prevent. How Physical (Mineral) Sunscreens Work Physical sunscreens, also known as mineral sunscreens, use ingredients like zinc oxide and titanium dioxide to form a protective shield on the skin’s surface. They work by sitting on top of the skin and physically blocking or reflecting UV rays away from the skin’s surface. Because they don’t absorb into the skin like chemical sunscreens, they are often the preferred choice for sensitive skin and post-treatment care.
Our Preferred Physical Option: Aspect Tinted Physical SPF 50+
Aspect’s Tinted Physical Sun Protection is a mineral-based sunscreen that uses 22.7% Zinc Oxide to offer broad-spectrum UVA and UVB protection. It’s enriched with Argan Oil and Gotu Kola to nourish the skin while providing effective sun protection. The colour-correcting tint leaves a sheer, natural finish, making it ideal for daily use - even for sensitive skin or those undergoing advanced treatments.
Pros of Physical Sunscreens:
Offers immediate protection upon application.
Gentler on sensitive skin and suitable for post-treatment care.
It provides a physical barrier that reflects harmful UV rays away.
Considerations:
It may need to be reapplied more frequently, especially if swimming or sweating.
While some mineral sunscreens can leave a white cast, Aspect’s formula minimises this effect for a flawless finish.
How Chemical Sunscreens Work Chemical sunscreens absorb UV rays and convert them into heat, which is then released from the skin. They contain ingredients such as avobenzone and octinoxate, which offer broad-spectrum protection. Chemical sunscreens are often lightweight, leaving no visible residue on the skin. Our Preferred Chemical Option: Aspect Sun CC Cream SPF 50+ Aspect Sun CC Cream SPF 50+ provides high sun protection while offering a touch of bronze to the skin. With its lightweight texture and blend of antioxidants, it defends against UV damage and protects against environmental stressors. The subtle tint evens the skin tone, creating a natural-looking glow without any heavy product feel. It’s a great choice for no-makeup days, or as a primer for makeup. Why We Love Aspect Sun CC Cream SPF 50+:
Broad-spectrum SPF50+ protection against UVA and UVB rays
The colour-correcting tint delivers a healthy, sun-kissed finish.
Water-resistant for up to four hours, making it ideal for outdoor activities.
Considerations:
Unlike physical sunscreens, which protect immediately upon application, they require about 20 minutes after application to become effective.
Chemical sunscreens can sometimes irritate very sensitive or reactive skin, especially in those with conditions like eczema or rosacea.
These sunscreens absorb into the skin to neutralise UV rays, which might not be ideal for clients who prefer a product that sits on the skin’s surface.
Why Our Clinic Prefers Physical Sunscreens
Our clients overwhelmingly favour physical sunscreens, and it’s easy to see why. Physical sunscreens like Aspect Tinted Physical SPF 50+ provide a natural shield against harmful UV rays without absorbing into the skin, making them ideal for those with sensitive skin or anyone undergoing advanced skin treatments. The tint helps even out skin tone and reduce redness, leaving a soft, natural glow. Plus, with their immediate protection, there’s no need to wait 20 minutes after application before going outside.
Choosing the Right Sunscreen for You Ultimately, the best sunscreen is the one you love to wear every day. Whether you prefer the immediate protection of a physical sunscreen like Aspect Tinted Physical SPF 50+ or the lightweight finish of Aspect Sun CC Cream SPF 50+, finding a product that fits your lifestyle and skin type is essential. Daily use is the cornerstone of healthy, glowing skin, and choosing a high-quality SPF ensures you’re getting the most out of your skincare routine. Want to try our sunscreens out for yourself?
