When I first received this product, the weather had not reached the 90 degrees in Texas, and it almost seemed like the perfect SPF. But not that the summer is technically here in Houston, this product seems very unsuitable for me. My skin gets more oily in the hot weather and this product just floats on my skin, rubbing off at any point and making wonder if there is any sun protection left. I also noticed that now that I am about halfway through the bottle, the consistency is more runny. I do not like this product under these mentioned conditions.
