I am naturally a pale WASP, so I use sunless tanning lotion year round and have been using them for at least ten years. They have gotten exponentially better throughout time and today there are a few that are absolutely wonderful. My favorite, however, is Skinceuticals Sans Soleil, It delivers an even, natural-looking tan. Most self-tanning products use the tanning agent DHA (dihydroxy acetone),which can cause dryness and create an uneven, unnatural-looking tan. Sans Soleil contains erythrulose, a unique DHA enhancer. The combination of DHA and erythrulose helps ensure a more even, streakless, longer lasting tan without increasing dryness.
I also really like the Clarins Radiance-Plus Self Tanning Cream-Gel. It provides an even, natural looking tan.
The self tanning mist works really well also. The spray allows for an even application. The only thing I don't like about these is that alot of the spray gets wasted, and can leave color on the floor or furnishings you spray beside. Mystic Spray Sunless Tanner is a good one.
You can also get an at-home airbrush gun. It's the GlowFusion AirGlow and it blows out a sheer, vapor-light, even mist in an cocoa-infused GlowFusion Micro-Nutrient Tinted Protein Tan Mist that dries on contact.
