Tanning products, both sunless and sun, go to work on the epidermis, or the outside layer of your skin, and not the dermis or inner layer. However, the layer of epidermis that is affected by sunless versus the layer affected by sun tanning products differs.
Sun tanning lotions, sprays, gels or foams, go to work on the stratum basale or deepest layer and sunless tanning items go to work on the stratum corneum or outermost layer.
WHEN TO APPLY:
Since most self tanning lotions have no sunscreen for protection outdoors, the best time to use self tanners is at night before going to bed.
If done earlier, allow a minimum of two hours and test for staining before putting back on your regular clothes. If your lotion contains extra coloring formula or if you're using a spray, staining could be a major issue and you won't to go to bed and stain bedding; so use these types of products earlier in the evening or when you have more time to "dry" after applying (at least a few hours).
WHAT TO DO:
Gather your necessary items together. Choose what you want to wear if you want tanning lines, whether it's a swimsuit, undergarments, etc. Use caution in your choices because the product may stain or run so choose old clothing, especially without nylon (permanently stains this fabric), and not loose clothing (to inhibit runny lotions). You will also need to be able to shower or wash beforehand.
Get a cotton washcloth or whatever you use to exfoliate your skin (sponge and other product, etc.), soap, any moisturizer you may want to use, your self tanning product, disposable clear gloves, a nail brush, a ball cap, hair pins or accessories to keep hair from your face, a sponge roller brush or paintbrush if you will apply product to your back, and access to a clock.
