Chemical sunscreens contain organic compounds like oxybenzone, avobenzone and octinoxate that create a chemical reaction that changes the UV rays into heat which then gets released by the skin. Chemical sunscreens often feel nicer on the skin and often have the added benefit of peptides, antioxidants and hydrators in their formulation so they are nicer for daily use but they can sting the eyes and are more likely to cause allergic reactions.
How much sunscreen should I wear?
Most of us don’t wear enough sun protection to get the full benefit of the product. The standard rule is that you need to use an ounce (or a shot glass worth) of sunscreen if you want all over coverage. For the face you need on average the size of a 10pence coin spread evenly over the face.
I have SPF in my foundation won’t this do?
You should not rely on foundations, makeup, powders or BB creams with SPF alone as your sun protection as most of us don’t apply these in liberal enough quantities or regularly throughout the day to make them protective.
When should I apply sunscreen?
Sun protection should always be the last thing you apply to the skin. Any moisturiser or lotion applied to the skin after sunscreen will dilute its protection. No sunscreen can be entirely waterproof so for best protection reapply your sunscreen after water exposure, heavy sweating or after 2 hours.
Look for broad spectrum sun protection with an SPF of 30+ to be #SunSmart. We recommend Oclipse Sun Spray SPF 50 or Oclipse Smart Tone Spectrum SPF 50 Both by ZO Skin Health
