I am always searching for a bargain and the No Ad Sport SPF sunblock lotion definitely qualifies. I have been using this brand for many years now and have been very pleased with the protection it provides against the sun's harmful rays. My daughter has extremely sensitive skin and she has a tendency to burn easily. She has never had a sunburn while using this product. Scent The scent of this sunblock is not overpowering and it has a pleasant subtle quality. Absorption The No Ad sun block is a little thick and difficult to spread evenly over your skin. It takes more effort to rub the product into your skin and it does not absorb quickly. Longevity I have found that this sun block needs to be applied about every four to five hours in order to ensure protection from the sun. It is a fifty SPF and this is adequate and effective. I also appreciate the fact that this product is a sport lotion and it continues to work well, even when you are sweating in the sun. Effectiveness I usually reapply the sun block after swimming because it seems to be sweat proof but not necessarily water proof. Overall I highly recommend the No Ad Sport SPF 50 sunblock to anyone who is looking for a high quality sunscreen that is a real bargain!
