Sunscreens do not dissolve easily

While sunscreens may help in reducing tanning to some extent, one of the main problems faced is that they do not dissolve quickly.
Even if a small amount of sunscreen is applied, it will form a thick white layer on the skin
If the user is in a hurry, and does not check in the mirror, they will not be aware of the fact that the lotion is still visible
Only when some one who sees them, will notice and comment on it, does the person realize that the lotion is not dissolved, and she has to rub it to get it dissolved.
A quick dissolving sunscreen will be greatly appreciated.
