Applying sunscreen every day will protect your skin from the harmful UVA and UVB rays emitted by the sun all year round. If you're ready to incorporate sunscreen into your everyday skincare routine, here are some of our top tips to help you to get the most value from the skin-boosting ingredients in your favourite products.
One of the most-searched skincare queries is whether sunscreen should be applied before or after a moisturiser. There isn't a one-size-fits-all answer here, as it really depends on which type of sunscreen you prefer to use.
When to Apply a Chemical Sunscreen
Chemical sunscreens are formulated with chemically active ingredients, which can only provide optimal protection from UV rays when they have been properly absorbed into the skin. So, if you prefer to use a chemical sunscreen, we always recommend applying it to freshly cleansed skin before your moisturiser and any other serums you like to use.
When to Apply a Physical Sunscreen
Physical sunscreens are also sometimes referred to as mineral sunscreens and they work to protect your skin by acting as a barrier. For this reason, it's important that you apply a physical sunscreen after you've already applied all your other skincare products.
The Obagi Sun Shield Mineral Broad Spectrum SPF50 is one of the best examples of a physical or mineral sunscreen. This fast-absorbing formula features 15.6% zinc oxide and 6.2% titanium dioxide for comprehensive UVA, UVB, infrared and HEV light protection, all of which can lead to premature skin ageing.
How to Tell the Difference Between Physical and Chemical Sunscreen
It isn't always easy to identify the type of sunscreen you're using because brands don't always put this information on the packaging of their products, however a quick look at the ingredients can provide you with all the information you need to know.
Physical sunscreens are formulated with ingredients including zinc oxide and titanium dioxide. Conversely, chemical sunscreens are formulated with ingredients including octisalate or avobenzone.
Today, many sunscreens use a combination of physical and chemical ingredients in order to provide optimal levels of protection from the sun. The Skinceuticals Advanced Brightening UV Defense SPF50 is an excellent example of a hybrid sunscreen, as it's formulated with octocrylene which is a chemical sunscreen, and titanium dioxide which is a physical sunscreen.
Can I Mix Sunscreen and Moisturiser?
We don't recommend mixing your sunscreen in with your moisturiser, as this can minimise the overall efficacy of your sunscreen. Instead, apply all products in your routine separately to ensure you're getting the maximum benefits of all the active ingredients.
How Much Sunscreen Should I Apply to My Face?
High quality sunscreens provide excellent protection from UVA and UVB rays, however it's really important to ensure you're applying enough to experience the full benefits. We recommend applying at least half a teaspoon of sunscreen to your face and neck at least 20 minutes before exposing your skin to the sun.
Should I Reapply Sunscreen?
Yes, it's incredibly important to consistently reapply sunscreen throughout the day to ensure that your skin is continually protected from UV rays. It is particularly important to reapply after you've been sweating or have spent time in water, as this can wash away sunscreen and compromise its sun protection benefits.
