Skin Biology & Its Roles

"Healthy skin is the reflection of overall wellness.", Dr. Howard Murad. Your skin tells others how healthy you are. It represents you yesterday, today and tomorrow. Therefore, "Be good to your skin, you will wear it for the rest of your life!".


Yes, everyone wants to have a perfect skin glowing with health and vitality,  free from lines and wrinkles with a silk like texture. For most of us achieving and maintaining a youthful complexion takes time, effort and expense.


Our skin's health is a reflection of our environment, general health and even stress levels. And it's there for all to see! If we're unwell or suffering stress our skin will suffer; likewise if we're frequently exposed to extreme weather conditions. With that in mind our approach to better skin should begin with an analysis of lifestyle.






Genes and some kinds of good luck often determine good skin, but the most fundamental factor is correct care from its owner. Part of this care is to find a good and trust-worthy beauty therapist who will choose great products to suit your skin and give you a valuable advice on skin care routines. The philosophy is "Beautiful skin begins with exceptional skin care including suitable products and beauty therapist."



Is there a single solution to skin care guaranteed for all? No. Whilst our skin is a reflection of our individual lifestyle and health we do tend to fall into a set of categories which provides a guide to an individual care regime. Part of this care is to find the right products for you.



Keeping this in mind, we offer customers a free skin consultation online and via phone, subject to availability, using questionaires, photos and discussion as input to our analysis. We know no two skins are the same! Our beauty therapists will choose the right products for each of customer and set up a customized routine for you. Finanally we follow up customers' skin improvement over the course of use.



In special cases, for instance speical skin diseases, in which we are unable to help as skin and beauty therapists, we will refer customers to appropriate practices for treatment.



The Skin is the largest organ of the body and provides a protective outer layer to the underlying structures, prevents the invasion of bacteria and protects the body against foreign objects including ultraviolet light, wind and dust.


The Structure of The Skin

The skin is made of three main layers:


1. The Epidermis - the outermost layer or the surface of the skin where melanin-forming cells called melanocytes are formed. Melanin protects the body from harmful effect of ultraviolet lights and changes the skin colour when exposed to the sun. In this layer the development of new cells occurs. The process is called mitosis occurs and leads to the gradual displacement of the older cells towards the surface of the skin. Using the right scrubs will benefit skin and improve skin texture. 


2. The Dermis - the middle layer just beneath the epidermis. It supports the epidermis and provides strength, contouring, smoothness and elasticity for the skin. It contains tough connective tissue, blood and lymph vessels, nerve endings, hair follicles, sweat and sebaceous glands, and papillary muscles. In this layer the highly sensitive and fibrous connective tissue provides collagen, elastin and fibroblast cells in order to give elasticity, resilience and produce collagen to support the skin.


3. The Hypodermis - the innermost layer. It contains adipose or fat tissue and areolar tissue which provides collagen, elastic and reticular fibres. This is the connection between skin and underlying muscles.


Function Of The Skin

1. Protection - the skin acts as a protective cover for the underlying internal organs. It contains sensory nerve endings preventing the body from further injury. The skin is also waterproof and prevents the absorption of water and the loss of essential body fluids. 


2. Temperatural Control - when the body temperature rises, the capillaries in the skin dialate and the heat from the extra blood is lost by radiation, conduction and convection. When the body temperaturer lowers, the capillaries constrict and maintain the heat in the body. In particular the evaporation of sweat from the skin's surface regalates the temperature of the body.


3. Sensation - when stimulated by external stimuli, the sensory nerve endings in the skin send messages to the brain which, in turn, responds via the motor nerves. The sensory nerve endings in the skin react to heat, cold, touch, pressure and pain.


4. Absorption - the thin layer on the surface of the skin, the stratum corneum, can absorb small amout of special cream used to improve very dry skin types. This is a useful way for cream to penetrate into the skin delivering relief.


5. Excreation & Secretion - excreation uses sweat glands to eliminate waste from the skin. Secretion is the process of sebum production from sebaceous glands. This helps to keep skin smooth, soft, supple and intact.


6. Vitamin Production - under a certain level of sun, ultraviolet rays convert 7-dehydro-cholesterol found in sebum into vitamin D  which is neccessary for the absorption of calcium and phosphorus required for healthy teeth and bones.  


Skin Types & Their Characteristics

Normal Skin

The skin has an even skin colour and a high degree of elasticity. It looks clear. It is soft and smooth to touch while feels neither tight nor greasy. The epidermis is of an average thickness.


Dry & Dehydrated Skin

Sensitive Skin

It feels tight after washing. It also has a thin epidermis and a translucent surface. It often turns red and blotchy when reacts to external stimuli. Winkles, dry flaky areas and dilated capillaries often appear on a sensitive skin.

Thick epidermis, sallow complexion, shiny appearance, open pores, especially on T-zone, blackheads and pustules usually appear on an oily skin.
