What is zinc oxide?
“Zinc oxide is a mineral derived from the naturally occurring compound, zincite, when it’s combined with oxygen,” explains Dr Ana. “And it has been used as an ingredient in the cosmetics industry for years.” As well as finding it in mineral sunscreens you can also find it in products that help heal the skin as well as keeping oil and shine at bay.
What are the benefits of zinc oxide to the skin?
We've outlined the four key skin benefits of zinc oxide.1) Protects against UV damage: Not only does zinc oxide protect the skin from the sun, but as a potent antioxidant it gets to work on fighting damage from other stressors such as pollution.
2) Anti-inflammatory: “Zinc oxide is known for being able to reduce inflammation so it’s particularly useful for skin types that suffer with inflammation, redness, acne or hyper pigmentation,” says Dr Ana.
3) Great for spots: “It is all-round anti-acne hero as it is non-comedogenic, which means it won’t block pores, inhibits excessive oil production thereby giving a mattifying effect and soothes redness caused by inflammation from breakouts,” says Dr Ana.
4) Reduces further pigmentation: “Due to its sunscreen and anti-inflammatory properties, it is also useful as an anti-pigment ingredient to help prevent further hyperpigmentation in patients who are prone to this,” says Dr Ana.
Are there any side effects to zinc oxide?The short answer is, no! “There have been no reports of certain skin types that are unsuitable for using zinc oxide as it is known to be non-allergenic and non-comedogenic,” says Dr Ana who goes on to advise that whenever you introduce a new product into your regime you should always do a patch test first, especially if your skin is particularly reactive.
Is mineral sunscreen better?
Should I use a chemical or physical SPF? has always been a debate in the beauty world over. The main difference between the two is that a mineral (also called physical) sunscreen sits on the top of the skin providing a protective barrier and reflects the UV rays away. They used to be slightly chalkier in consistency and leave a white cast on the skin but thankfully formulations have moved on and this is rarely an issue anymore.
A chemical sunscreen uses active ingredients to absorb the UV rays, turn them into heat and release it back through the skin. But is one better than the other? “There are marginal differences between the two types but what’s important is finding a sunscreen that suit your individual needs and that you like using on a daily basis,” says Dr Ana. “Mineral sunscreens are known to be very gentle, especially around the eyes and because a mineral sunscreen is anti-inflammatory and non-comedogenic, they lend themselves particularly nicely to acne and pigmentation prone skin.”
How to use zinc oxide in your skincare routine
How you use zinc oxide really depends on the type of product you're using it in. If it is in an SPF that you want to apply it as the last step in your skincare routine and before any make-up and then reapplied throughout the day especially if you are on holiday and swimming.
“Soothing cleansers containing zinc for the anti-inflammatory or anti-acne effect can be used both mornings and evenings or if you’re using a zinc oxide cream for its healing, anti-inflammatory, wound healing or barrier repairing effects, I suggest using it at night time as thesis the time that your skin undergoes most of its repair process,” advises Dr Ana.
