Sunscreens are chemical or physical barriers to UV radiation. Chemical sunscreens are the lotions you apply to your skin that absorb the UV radiation. Some contain PABA (para -aminobenzoic acid) that absorb the UVB rays. Some have benzophenone that absorb both the UVB and UVA rays. The effectiveness of these chemical sunscreens depends on what's actually in it and its ability to withstand swimming and sweating. Sunscreens have SPF (sun protection factor) ratings, too, which indicate how much sunburn protection they have relative to unprotected skin. The higher the number, the more protection, up to a certain point (which differs among experts). To get a sunscreen tan, you must apply the sunscreen (fairly liberally, approx 2mm thick) for it to work. It's better to put it on 30-60 minutes before going out in the sun, so it can penetrate and bind to the skin.
There are many good solutions to get a sunscreen tan. Would you like to have an inexpensive, easy to apply, neutrally scented sunless tanner with quality sunscreen? Then, Alba Botanica Advanced Sunless Tanning Lotion with SPF15 is for you. The product has minimal oil, though your face can still look shiny because of the silica content. Apply this in the morning, dusted a light coat of a pressed powder foundation with SPF on top, and your beauty routine is done.
Because this is a light product, you can use it daily without buildup. Apply it heavily, the way you should apply sunscreen. The light pineapple/tropical smell won't get to you later in the day. The only drawback is a moderately short shelf life: don't buy more than you can use up in six months - after six months the product develops a strong odor.
Sunlogics by Beauticontrol is on the Short List of sunless tanners that smell great.
Sunlogic's color is solidly medium and solidly brown. Because of the sunscreen ingredients, it will be white on your skin, and, just as with sunscreen, don't rub it in until all the whiteness is gone. It will disappear in a few minutes on its own. It smells as good as Aveda Sans Sun, but goes much farther.
While some people say you can't use sunless tanner for a sunscreen tan, it wouldn't hurt to have a sunless tanner with some decent sunscreen for those mornings when you want to put sunless tanner on your face and go. Sunless tanners for sunless sunscreen tan can work for the minor sun exposure we get throughout the day. They do not work in situations where you need to reapply sunscreen frequently, because it needs to be reapplied every two hours when you are spending time outdoors. But this can cause another problem: reapply a sunless tanner with sun screen every two hours and you are going to be a nice orange mess. Also, after you have applied a sunless tanner, you should avoid applying any lotions on top, including sunscreen, for about three hours.
So, getting a sunscreen tan requires  particular attention. You must never rely on a sunless tanner with sunscreen if you want to stay in the sun long. Sunscreen must be reapplied every hour and a half, and you can't do that with sunless tanners.
