There are many causes for hyperpigmentation and uneven skin tone, and there are different depths of damage in the skin. Systemic pigmentation is damage at the cellular level and has affected the cell itself. This is very difficult to correct at a superficial level, and sometimes even the most aggressive medical treatments will not be able to eliminate the problem. Surface pigmentation, discoloration at the superficial level, is generally more successfully treated. However, much can be done to overall brighten and lighten skin and protect from further damage. Beware of overuse of products that contain hydroquinone. This ingredient is in many over-the-counter lightening products and the skin may develop a resistance or immunity to it or may begin to darken skin even more.
Two main factors that affect hyperpigmentation are the sun and heat! So wear Daytime Defense SPF30 at all times and stay COOL! Rhonda Allison’s Skin Brightening System is designed for all skin types and provides a variety of choices to customize for specific needs.

Pigmentary Dyschromias – Melasma
There are variables in depth of dyschromias (hyper-pigmentation) and skin will respond inconsistently; a Woods Lamp may aid in classifying depth of melanin/pigmentation, but it does not predict clinical response to peels.
The combination of epidermal and dermal dyschromias/hyperpigmentation is more common than earlier research has shown.
When examining the skin, three types of hyperpigmentation will present itself:
- EPIDERMAL – Surface is light brown and not quite as dense.
- DERMAL – Skin is deep brown, ashen-gray and appears more solid.
- MIXTURE – Both levels are usually dark brown.
Melanocytes are basically brain cells. These cells do not divide very well and are limited in number and are difficult to work with. When they are destroyed, there will be an absence of melanin, resulting in hypopigmentation. When the cells are over-stimulated, the skin becomes hyperpigmented. Moles are formed from the plumping up of melanocytes cells.
