Sandy:Point 1. There is no question but that there is a "cumulative effect" that must be taken into consideration for the most sensitive skin types (subtypes). After the 3rd session you usually don't have problems unless you increase the time too fast. The reasons for this are not clear but I have two articles that shed some light on the subject that I am reviewing. When I am sure I understand this issue, I will write an article explaining it.Point 2. The "official" description of "sunburn" is "persistent" eryethema (redness) continuing after 24 hours. Therefore, what we are observing is not a sunburn in the classical sense.Point 3. The old wives tale that clients shouldn't take a shower after tanning is just plain silly. Unfortunately Steve Cheney (who should know better!) compounded and perpetuated this "myth" with his comments in this month's Tanning Trends. The response of the skin to UVR is instataneous and once the photons penetrate the skin, they certainly aren't going to be affected by a shower or a bath! Point 4. The reason that the tanning process is called "delayed pigmentation" is that it takes time (24 - 48 hours) for the process of oxidizing the melanin granules (calloed malanosomes) to be completed. Whether or not you shower is immaterial.Point 5. In fact, there have been two studies (that I am aware of ) showing that showering just before tanning is beneficial.Point 6. The only way bathing (or showering) after a tan could affect the process is if a "scrub" was used that removed some of the dead (oxidized) cells from the surface of the skin. Hope this helps to clear up this matter.Don
