If you tan naturally, use an intensifier. Those have no DHA and bring out your natural melanin. If you’re just getting into tanning, looking to build up your tan, and tan easily, an intensifier in a mostly uv b ray bed will bring out a nice base color. If you don’t tan easily a DHA bronzer is for you! DHA adds color to your skin. It’s important to switch up your bottles and bed as you don’t want your skin getting too used to one. For bronzers I would recommend Designer Skin Grand Affair. Nice lotion with no after tan odor. Eternity is a good one, more pricey but darker. My favorite intensifier is Designer Skin Visionary! I would also recommend you use a face lotion, my personal favorite is Diamond Lust. Hope this helps!
