"The main benefit of sunblock is, of course, preventing ultraviolet rays from penetrating the skin. This is important in preventing burns and blistering. In addition, sunblocks can help minimize the "aging" effect sun exposure has on the skin, which includes wrinkles and a "leathery" appearance. Many sunblock products provide a moisturizing effect on the skin. A good sunblock also allows people to spend more time out-of-doors than they could without the protection" -Livestrong.com
Here are my Top 5 recommendations if you want sunblock that's light on the skin but has a high SPF:
1. NEUTROGENA Fresh Cooling Body Mist Sunblock SPF 45
2. NEUTROGENA Ultra Sheer Body Mist Sunblock SPF 45
3. AVENE SPF 50+
4. AVEENO Continuous Protection Sunblock Lotion SPF 30
5. L'OREAL UV Perfect SPF 50
Just remember that just because you're wearing sunblock, doesn't mean it's okay to expose yourself in direct sunlight. Especially if toner is a part of your daily regimen, it's still advisable for you to avoid direct exposure from the sun.
Hope this helped! Have a great sunshiney day!
