Dr. Avi Bitterman, a dermatologist in New York, posted the photograph of the woman on Twitter on Friday. It shows sun damage on the skin of her neck, and far less discoloration and fewer wrinkles on her face when she applied sunscreen. The was easy to differentiate between the woman’s face where Sun Protection Factor (SPF) was applied and her neck where it was not. As her neck looked discolored and wrinkled her face still looked better.

According to US Food and Drug Administration, Sun Protection Factor (SPF) is a measure of how much solar energy (UV radiation) is required to produce sunburn on protected skin (ie, in the presence of sunscreen) compared to the amount of solar energy required to produce sunburn on unprotected skin.  Sunburn protection also increases as the SPF value increases.
