Foundations Before & After UV Photos |
|
Standard photography produces images of the skin’s surface as seen by the naked eye in visible light conditions. When pigmentation spots (including freckles, sun spots and age spots) are noticeable in visible light, a large accumulation of the skin pigmenting agent melanin has already occurred. To examine the early development of pigmentation spots resulting from sun exposure, a UV(ultra-violet) camera is utilized. This photographic technique reveals pigmentation changes that are happening beneath the skin’s surface, before they are visible to the naked eye, and can demonstrate UV protection by a topically applied sunblock or sunscreen.
What to look for: The UV camera is equipped with a UV light flash. Increased absorption of UV from the flash is demonstrated on the UV pictures as darkening. The melanin in pigmentation spots absorbs the UV light and therefore appears darker in UV photographs. Use of a sunscreen that chemically absorbs UV light to protect the skin will make the skin appear uniformly darker. A sunblock will reflect away the UV rays preventing absorption into the skin
- the UV pictures will not appear significantly darker. Since sunblock and sunscreen agents prevent UV absorption into the skin, the pigmentation spots will be less apparent. When using an effective sunscreen or sunblock, the skin’s pigmentation spots should appear less noticeable since the spots are being prevented from absorbing UV energy. |
