Popular Q&A's for sunscreen
1. What is the difference between Physical sunscreen and Chemical sunscreen?
There are two common types of sunscreens; chemical absorbers and physical blockers. Chemical sunscreens use synthetic chemicals such as Oxybenzone, Octinoxate and Homosalate to absorb the sun's UV rays before releasing them safely. They are often easier to blend into the skin and absorb quickly; however, some chemical UV filters can cause allergic reactions and irritation in sensitive skin. At Nourished Life we only stock physical sunscreens.
Physical sunscreens go by multiple names like natural sunscreen and mineral sunscreen. Natural sunscreens contain minerals such as Titanium and Zinc to deflect the sun's UV rays, so they don't penetrate the skin. They are traditionally thicker and whiter than a chemical sunscreen, which makes it easier to see where it is applied, ensuring sensitive areas are covered. Once applied, natural sunscreens instantly protect your skin. Chemical sunscreens, on the other hand, need about 20 minutes to sink into your skin before they can absorb UVA/UVB rays.
2. What is the best sunscreen to choose that won't harm the environment?
Most traditional sunscreens use ingredients that can cause harm to marine life and the delicate coral reef ecosystem. One of the main ingredients to avoid is oxybenzone, which you won't find in any of our sunscreens on Nourished Life. To help minimise your impact, keep an eye out for sunscreens labelled "reef friendly" or "ocean safe" such as SunButter SPF 50 Water Resistant Reef Safe Sunscreen and Life Basics SPF 30 Natural Coconut Body Sunscreen.
3. At what stage of my skincare routine should I be applying a facial sunscreen?
A general rule of thumb is to apply active ingredients like serums first, then moisturiser second, followed by a physical sunscreen as the last layer then makeup on top if desired. Take your time between layers by letting each product absorb before moving on to the next. Read our guide on facial sunscreens.
4. Should I wear sunscreen if staying indoors?
Yes! It is recommended to wear broadspectrum sunscreen every day whether you are indoors or outdoors to protect your skin from skin cancers and premature ageing. There are two types of UV rays; ultraviolet A (UVA) and ultraviolet B (UVB). UVA is around all year long and can cause premature aging like wrinkles, sunspots and fine lines. UVB is generally higher in the Summer months and is what causes sunburn and damage to DNA in skin cells. UVA rays have a longer wavelength than UVB rays, meaning windows and a cloudy overcast day won't protect you from the harmful sun rays!
With all sunscreens, avoid contact with eyes and if irritation persists discontinue use. Sunscreen is only one part of sun protection. Wear protective clothing, hats and sunglasses when exposed to the sun, and stay in the shade where possible. Prolonged high-risk sun exposure should be avoided. Frequent reapplication and use in accordance with the directions is required for effective sun protection. Always read the label and use only as directed.
