What effect does UV have on the skin?
Effects of UV on the skin mainly include sunburn, tanning/ pigmentation and premature ageing. UV damage can also includes eye damage and can also cause skin cancer.
What does an SPF do?
An SPF (Sun Protection Factor) is a measure of how well a sunscreen will protect skin from UVA/UVB rays (the kind of radiation that can cause skin damage) and can contribute to skin cancer. For example If your skin would normally burn after 10 minutes in the sun, applying an SPF 15 sunscreen would allow you to stay in the sun without burning for approximately 150 minutes (a factor of 15 times longer). This is a rough estimate that depends on skin type, intensity of sunlight and amount of sunscreen used. SPF is actually a measure of protection from amount of UVB exposure and it is not meant to help you determine duration of exposure.
How can we prevent sun damage / pigmentation?
Top up regularly with a UVA/UVB SPF protection. UVA stimulates the pigmentation in your skin (melanin). This is responsible for your tan and also those unwanted dark patches (pigmentation). These sun spots may take up to 10-20 years to develop, so if you have noticed some showing, it could have been caused from when you were younger. Pigmentation can be treated with laser however to prevent this we would recommend the Hydraderm Longue Vie Soleil Facial treatment – It helps promote the melanin in your skin for an EVEN tan prior to your holiday. It also helps fight,neutralise free radicals caused by UV rays therefore helping to prevent skin ageing. Finally it provides moisture to sun exposed skin. The Newhite skin care range is also great for clients concerned with pigmentation, (ask your Guinot therapist for more information)
