Will Self-tanning Lotions Help Protect Me From the Sun?

     Self-tanning lotions and solutions have dihdroxyacetone (DHA) as an active ingredient. DHA causes a browning reaction when exposed to your skin. It usually comes in a 3-5% concentration in your self-tanning preparations. The lower percentage produces mild tanning (lighter shades) and the higher percentage produce a darker color (darker shades). So if you want a darker tan pick a higher concentration preparation. The depth of the color is also affected by thicker skin (with more protein content). Therefore, rough skin growths and thickened skin on your elbows, knees, palms, and soles will stain a darker color. DHA can also stain hair and nails but does not stain mucous membranes (wet part of your lips, mouth and eyes)

     DHA is colorless and stable. It is nontoxic if ingested and has rare side effects. There are only a few case reports of an allergic skin reaction. Self-tanning lotions have a comparable SPF of 3-4 for only up to 1 hour. Most dermatologists recommend a SPF of 30 or higher. Therefore, self-tanning lotions DO NOT offer you adequate sun protection.. You still should apply sunscreen with a SPF > 30. Check back with us for more on sunscreens later.
