Are products higher than SPF 15 really necessary?
Yes. Although a SPF 15 is effective in providing sun protection, some people require greater levels of protection. High SPF products block more UVB and UVA rays which penetrate the skin deeply, and are relatively consistent year round. UVA can contribute to premature aging, wrinkling and pre-cancerous changes. These products also provide protection for longer periods of time (for those who work outside or participate in prolonged outdoor activities.) Many dermatologists recommend regular use of a high SPF sunscreen to prevent sunburn and reduce the amount of sun damage caused by unprotected exposure. Research estimates that regular use of highly protective sunscreen (SPF 15 or higher) for the first 18 years of life could reduce the incidence of certain types of pre-cancerous changes by nearly 80%.
