Sun Care Protection

Types of Sunscreens

Protection factors are physical and chemical

Physical

This type of sunscreen is an opaque film used on the skin to reflect UV radiation.  The most common example is zinc oxide cream, often called zinc cream.  It forms a dense barrier and blocks perspiration, so its use is limited to small exposed areas such as the bridge of the nose and the cheekbones.

Chemical

This type of sunscreen can be a water-soluble or oil-soluble chemical that absorbs UV radiation reducing its intensity.  It comes in the form of cream oil lotion or milk and some brands are waterproof.

The best type of sunscreen product is a broad-spectrum sunscreen that will filter out both UVA and UVB rays.

SUN PROTECTION FACTOR (SPF)

These sunscreens are graded by their SPF

SPF is a number that represents how long a person can stay out in the sun without burning while using the product. It is a measurement of minimal erythema dose (MED) which measures how much time passes without the skin turning red from irritation when exposed to the sun.

For example, a person who could stay in the sun for 10 minutes before burning could extend that period to 60 minutes without burning by using a sunscreen with an SPF factor.

SPF’s are designed to prevent sunburn. They do not measure how much light is blocked from the skin, or how much UVA and UVB rays are being screened.

 SUN SKIN TYPES

The universal system for classifying skin types when discussing sun exposure is

Fitzpatrick Skin Typing

This typing is named after its originator Dr Thomas Fitzpatrick.  It is an indicator of skin colouring and we use this skin typing in our salon when we do invasive treatments such as electrolysis or IPL so we can best assess and advise you on protecting your skin in the sun after the treatment.  We also advise our facial clients on their sun care.  If you would like to know your Fitzpatrick Skin Typing check this form.

As you can see, the scale has a lot to do with hereditary and genetic skin characteristics.   When you next visit our salon we can assist you in choosing your solar care based on the amount of time you plan to spend in the sun,

Rules for Applying Sunscreens

For maximum benefits

Apply 30 minutes before going into the sun

Reapply regularly (every 4 hours) during the day.

Water-resistant sunscreens should be applied approximately 30 minutes before going into the water.

Reapply after swimming and exercising.

Without sunscreen, rays are absorbed deep into the epidermis

With sunscreen, rays are deflected away from the skin.
