Sunscreen Review

NATURAL PHYSICAL vs CHEMICAL

NATURAL:

Natural sunscreens are a physical barrier of protection for the skin. They can contain ingredients such as Zinc Oxide that helps reflect the suns harmful rays. This is different to chemical sunscreens, which absorb and filter UV rays. Natural physical sunscreen particles sit on top of the skin acting as a reflective UV layer.

CHEMICAL:
Chemical sunscreens work by absorbing UV rays through the superficial layer of skin  before it can penetrate into the deepest layers of the skin and therefore cause long term damage.  Chemical based sunscreens are typically a combination of active ingredients such as; octocrylene; oxybenzone; avobenzone; octisalate; homosalate and octinoxate. There is controversy around chemical sunscreens, as some of these ingredients can be absorbed into the bloodstream. Some of the chemicals found in these sunscreens, and in many other skin care products, have been shown to cause hormone disruption once in the bloodstream.

APPLICATION:

In our industry, we recommend as a general rule that you apply chemical sunscreens around 20 minutes before sun exposure so that  they are fully absorbed by the skin.

Where as physical sunscreens, can be applied as the last step in your skin care routine and will begin deflecting the sun’s rays immediately.

The SPF factor is all about the longevity of protection. If you would typically start to burn after 10 minutes of exposure, then an SPF of 15 will allow you 15 times longer in the sun. Keep in mind though, your SPF is not cumulative. Wearing a 50 + sunscreen and 15+ makeup over the top, does not mean you have 65+ protection. Its only as strong as the strongest spf.

FROM MY EXPERIENCE:

Physical sunblock tends to be:

  • Less irritating and preferred by sensitive skin

  • More moisturising, which can feel heavy on oily skin

  • Quiet occlusive on the skin which can cause more breakouts for acne prone skin.

Chemical sunscreen is a better option if you:

  • Have quite oily skin.

  • Want a sunscreen to soak in when swimming/ beach day/ playing sport.

  • Break out easily with sunscreens
