To begin it is important to recognise that we all need the sun, we need sun light. We dream about bright sunny days, we all love to sit in the sun. The sun helps to generate our Vitamin D levels to see us through the dark months of winter. So how can we do this without risking skin cancer and unnecessary skin ageing.
Sun exposure increases free radical damage & oxidative stress in your skin, which is a major contributing factor to premature skin ageing .Sun damage happens when the sun’s rays – UVA and UVB penetrate into the skin and damage the skin cells. If you get a bad burn these skin cells, even though they will heal, are permanently damaged. They continue to reproduce in the damaged form, which can eventually lead to skin cancers forming.
Wearing a high factor sun cream helps but, even with factor 50 you can get burnt. Why ? A couple of reasons
1.The current approach used to assess the protective efficiency of a sunscreen product is a worldwide method for the determination of its "SPF" which is based solely on ability to prevent erythema, i.e. UV-induced sunburn with visible redness.The disadvantages of the existing method of assigning SPF to skin care products is being increasingly recognized because it does not take into account the damaging effects of UVA and due to misinformation has inclined users of sunscreens to stay longer under the sun in the belief that they are fully protected.
2.SPF is the ratio of UV irradiation doses producing minimal erythema (MED) in sunscreen-protected skin vs. unprotected skin.
SPF does not refer to a sunscreen's potential to help prevent 90% of the visible signs of ageing — the sun protection needs to be broad spectrum to protect against UVA & UVB.
Most of us use a small amount of protection, we do not apply it well in advance of exposure and crucially, we do not reapply it, expecting our morning application to last throughout the day.
Also SPF ingredients do not protect against Infra red rays so we recommend that you use a daily application of a high grade antioxidant serum ( containing pure vitamin C and vitamin E in high concentrations) like Skinceutical C E Ferulic Serum every morning under your SPF to enhance your protection.
Sheer Mineral UV Defence
The SkinCeuticle range of SPF offers exceptionally high protection, yet they are light; they do not give your skin the white zinc effect. This medical grade skincare range is recognised by Dermatologists and Plastic Surgeons throughout the world. They are backed by science; the research is carried out in Duke University in the States.
