The closer to the equator, the darker the skin tone will be. When moving further North - - - > from the equator, the skin tone becomes lighter. Those who have lighter skin are at high risk for developing skin cancer, vascular damage and pigmentation. Those who have darker skin are at high risk for developing hyper/hypo pigmentation and keloid scarring. Basically, those who possess the ability to withhold a tan are at great risk for developing pigmentation. Lighter skin tones generate a lot of free radical damage within the cells environment where as darker skin tones absorb damaging molecular species generated by oxidative stress and provide higher protection against UVR — that’s a major plus for lowering the risk of developing skin cancer, actinic ageing (UV radiation induced damage) and vascular damage. The large and diverse mixed ethnicities of the world today dictates to the Skin Treatment Therapist that even the darkest of skin tones are at high risk for developing intrinsic conditions such as those who have inherited lighter skin tones — and vice versa.
