1. Balanced hydration

In module four, you begin to learn about all of the skin conditions, cells and systems responsible for secretions. A number of these have already been covered in previous modules; this final module brings it all together. Numerous factors control the secretions of the skin, some of these crossing over from the dermal to epidermal. We will examine the two categories that influence secretions with the external, that influences the epidermis, and the internal that influence the dermis.

2. The lymphatic system

In this unit of learning we will be covering the importance of how the lymphatic system maintains body and skin health by: Preserving fluid balance. Nutrition function and the Defense function.

3. Skin enzymes, amino acids and corneocyte compaction

Water regulates almost every enzymatic, and chemical reaction of the body. Consequently it has an effect on hormones, nutrients, oxygen and antibodies through the blood stream and lymphatic system. The formation of the amino acids found within the epidermis is linked to the keratinisation process, and the keratinocyte cell compacting to form a corneocyte. This process is linked to the keratohyalin granules, which are found within the keratinocyte in the granular layer. Keratohyalin forms dense cytoplasmic granules that promote compaction of the cell, as well as aggregation and cross-linking of the keratin fibres. Making this a vital step in the formation of the stratum corneum, barrier defence formation; as well as amino acids.

4. Essential fatty acid deficiency and Lipid peroxidation

Lipids play a major role in skin barrier defence systems, and the lipid composition of the bi-layers of the stratum corneum play a major role in determining what types of substances permeate the skin. Because one of the primary pathways for chemical penetration through the stratum corneum is these lipid and water containing spaces. Essential fatty acid deficiency is an aggravating factor in all skin conditions listed in my book, because it is a precursor, and aggravating factor of oxidative stress. As a result the cells such as the keratinocyte that are responsible for creating the first three lines of skin barrier defence will be compromised.

5. Impaired barrier defense systems

The acid mantle is sometimes referred to as the hydrolipidic film, which means a film of oil and water. A physical barrier that offers many benefits to the entire eco system of the epidermis and dermis. The occlusive and lubricating properties of the acid mantle slows trans epidermal water loss, stabilizes the bilayer structure, and supports lipid enzymatic action within the transitional layer. Including protection against allergens and bacteria by providing an acidic environment within which normal skin flora reside.

6. The Endocrine system

We know hormones play an important role in skin physiology, but how big a role do they play in skin conditions such as Rosacea, DHT acne and barrier disorders such as eczema? The endocrine system refers to the collection of glands of an organism that secrete hormones directly into the circulatory system to be carried toward a distant target organ. Hormones travel throughout the body, either in the blood stream or in the fluid around cells, looking for target cells. Once hormones find a target cell, they bind with the specific protein receptors inside or on the surface of the cell and specifically change the cell’s activities. The protein receptor reads the hormones message and carries out the instructions by either influencing gene expression or altering cellular protein activity. These actions produce a variety of rapid responses and long-term effects.

7. Hormonal mediated acne

Acne involves many cells and systems and all of those listed here have been part of the previous modules and units of learning. Much of our discussion today will refresh your memory of those diagnostic characteristics of texture, colour and secretions. We have learnt that there is a hormonal component involved in all forms of acne, and that the acne condition involves many of those cells involved with texture, for example the keratinocyte and of course your newly acquired knowledge about the endocrine system. Hormonal mediated acne is different in that there is the inflammatory response and innate immune system involvement and the hormonal influence on sebaceous secretions.

8. Visual analysis and diagnostic clues of secretion related skin conditions

Learn to link skin structure and function and find the leading cause of Essential fatty acid deficiency, impaired lymphatic system, Hormonal mediated acne and poor corneocyte compaction including the impaired barrier defense systems.

9. The practical assignment and assessment

In this unit we undertake a practical assignment. Continuing to follow our virtual client through from the consultation process, and using diagnostic forms and flow charts so as to logically reach a conclusion from the wide array of information gathered. This process teaches you how to think three dimensionally and recognize the causative agents to the skin conditions. The final assessment for the diagnostic characteristics of Texture, Colour and Secretions.
