THE IMPORTANCE OF SUNSCREEN



Did you know that 90% of the symptoms of premature skin aging comes from exposures to ultraviolet light: UVA or UVB from sunlight. This is why you need to use the proper sunscreen and also you need to know how to use it properly.

A good sunscreen should have a SPF of at least 15. What does this mean? SPF stands for Sun Protection Factor. This number is determined by exposing human subjects to a light spectrum which mimics the noontime sun. Some of the subjects wear sunscreen and the others do not. The amount of light that induces redness by the protected skin is divided by the amount of light that induces redness by the unprotected skin. This is how the SPF is determined. For example, a SPF of 15 will allow a person to stay in the sun 15 times longer. The person with no protection burns in 10 minutes versus 150 minutes with protection.

Ingredients is also a very important factor in determining a good sunscreen. Bonita Botanicals offers a sunscreen with a SPF of 30 and contains the following ingredients beneficial to providing the utmost protection for your skin: Titanium Dioxide & Zinc Oxide. The benefits include: true broad-spectrum UVA/UVB protection,
non-chemical sunscreen, transparent and non-whitening, moisturizing and healing properties, PABA-free and fragrance-free, elegant formulation ideal for daily use and can be applied under makeup, and formulated for skin sensitive to traditional sunblocks and post-treatment patients.

The other important factor is knowing how to use sunscreen. It should be applied at least twenty to thirty minutes prior to being exposed to the sun and should be applied generously. It is important that your skin has time to absorb it in order for it to work properly. To maintain protection, sunscreen should be reapplied often if active.
