Nothing is more startling than a woman with a flawless facial complexion and mottled, bony hands with bulging veins. The leading causes of hand photoaging are epidermal changes, such as actinic keratoses, fine wrinkles, and crepe-like textural changes and lentigines.
Hands, like the face, are the body parts exposed all year round, so the dermis layer and subcutaneous fat thinning occur due to ultraviolet light exposure and intrinsic ageing. This can lead to a skeletal-like appearance of the hands and prominent veins.
Although laser rejuvenation shows excellent results in treating lentigines (liver spots), it is vital to use a wavelength that targets the appropriate skin chromophore for treatment to be effective and to avoid unwanted adverse effects. A broad spectrum of wavelengths, such as triple waves laser, can be used because melanin has a wide absorbance range.
