Functions of Human Skin
Functions of Human Skin
The skin is the largest organ of the body. This elastic, protective covering is thinnest on the lips and eyelids and thickest on the palms and soles. Following are the six primary functions of the skin: Heat regulation – the skin regulates body temperature by sweating, which is the production of moisture by the sweat glands (suderiforous glands). The evaporation of this moisture enables the body to cool itself. Absorption – the epidermis layer of the skin contains an acid mantle layer which limits the amount of substances entering though the skin that affect the body to a minor degree. Secretion – the sebaceous glands excrete oil to lubricate and maintain the health of the skin. Protection – fat cells provide insulation and protection against trauma to the internal organs. The skin also protects itself from the harmful effects of light and acts as a barrier against the invasion of bacteria. Excretion – perspiration is the process by which the sweat glands excrete waste materials. Sensation – nerve endings in the skin allow us to feel heat, cold, touch, pleasure, pressure and pain.
3D Skin Rejuvenation™ from Cutera
3D Skin Rejuvenation™ from Cutera
Every person ages at a different rate and in different ways. Some develop redness, age or sun spots. Others have large pores, fine lines, wrinkles or lax skin. You may have one, two or all of these conditions. Cutera’s 3D Skin Rejuvenation takes a three-tiered approach to rejuvenating your skin for all of these conditions. LimeLight Facial or Solar Genesis are light-based procedures which address problems right at the skin’s surface - redness, mottled complexions, freckles and sun damage. Laser Genesis utilizes a laser to soften fine lines and wrinkles, shrink pores and decrease or eliminate redness found deeper in the epidermis. Laser Genesis has been proven to stimulate the creation of new collagen, giving your face a more youthful appearance. Titan is the newest category for skin fitness. The Titan uses infrared light to heat tissue in the deep dermis. Together you can have a 3D Skin Rejuvenation experience! Common Questions Who can be treated? Men and women of any age who wish to improve their skin can be treated. Skin which is lax, has surface wrinkles, redness, brown spots, or enlarged pores are the most common conditions to treat. What areas can be treated? The most popular areas for treatment are the face and neck, but other body parts such as the hands, arms and abdomen, are also frequently treated. What do the treatments feel like? LimeLight Facial and Photo Genesis deliver a series of pulses of light. When each pulse of light is delivered, you may feel a mild, brief pinching sensation. Laser Genesis treatments are gentle and soothing. During the session you will feel a series of warm pulses along your skin. With each Titan pulse, you will first feel cool, then a brief heating sensation followed by a cool feeling. Most patients are comfortable without taking any medication; a few prefer taking a mild pain reliever beforehand. How many treatments will I need? Each treatment regimen is different and customized to an individual patient’s needs. Most patients can expect between 2 and 6 treatments. Are there any side effects? The most common side effect is a slight redness or mild swelling in the treated area that disappears within a few hours. When will I see results? Immediate results are observed by some patients. More typically, you will see results in two to four weeks and improvements will continue for several months. How does 3D Skin Rejuvenation compare with other laser treatments? Most lasers treat only one or two aging conditions. They may diminish red or brown spots; they may just reduce lax skin. Only 3D Skin Rejuvenation from Cutera addresses all of the most common conditions of aging – age spots, sun damage, fine lines, wrinkles and lax skin.
Key Skin Care Ingredients
Key Skin Care Ingredients
Alpha Hydroxy Acids (AHAs) All alpha hydroxy acids have the effect of dissolving the bonds between skin cells, to allow for exfoliation that will bring newer cells to the surface. Each AHA also has additional benefits: Lactic Acid – hydrating and helps even skin discoloration Malic Acid – hydration Glycolic Acid – fast penetration [which can be a negative] and oil control Citric Acid – prevents and corrects the thinning of the skin associated with aging and aids in hydration Tartartic Acid – antioxidant action from grapes Mandelic Acid – possible effect on evening skin discoloration Many of the PCA SKIN® Daily Care Products contain a blend of lactic and citric acids which promotes healthy cell turnover and allows the products to remain pH balanced. Antioxidants Antioxidant – A group of vitamins, minerals and enzymes that help repair and prevent cell damage caused by free radicals.

Green Tea- Tea is an excellent source of antioxidant polyphenols and anti-inflammatory agents. EGCG (Epigallocatechin Gallate), which is a component of green tea, is considered the most powerful polyphenol of them all. It offers skin soothing benefits, protects the skin from UV induced damage and is being studied very carefully for possible anti-tumor and anti-cancer capabilities. Tocotrienols and Tocopherol (Vitamin E)- these forms of vitamin E have superior antioxidant benefits due to their exceptional ability to penetrate the skin cells. Grapes –The flesh, skin and seeds of the grape all contain polyphenols that offer many skin health benefits. Olives – a great source of antioxidant polyphenols and vitamin E. Retinol (Vitamin A)- has strong antioxidant properties along with the ability to increase cell turnover for healthier and brighter looking skin. Soy – the isoflavones found in soy are potent members of the polyphenol family. They work to plump and hydrate the skin. They fight aging and wrinkle formation by building the collagen matrix. They also effectively quench the free radical damage that speeds the aging process. Cherries- help to fight free radicals and acts as potent anti-inflammatory ingredients. Citrus Fruits – are a great source of polyphenols. A number of citrus fruits not only have antioxidant value but also increase the amount of vitamin C within the cells.

Skin Conditions
Skin Conditions
Acne – Acne is the most common skin condition in humans, affecting nearly 45 million Americans each year. Acne develops where there are more oil glands present, e.g. face, scalp, chest, back and neck. There are many different types of acne and each patient should be treated according to their particular case. Aging – Aging of the skin is a result of many different factors that can be broken into two categories: intrinsic and extrinsic. Intrinsic or uncontrollable aging is chronological and genetic. Facial wrinkling, expression lines and drier, more sensitive skin may be a result of intrinsic aging. The extrinsic or more controllable factors of aging refer to exposure to the sun and/or pollutants which cause a breakdown of the skin’s structure, leading to discoloration, wrinkles, skin growths and even cancer. Many skin scientists believe the extrinsic factors are to blame for 90% of the visible signs of aging. When attempting to correct signs of aging, it is important to use products that not only treat, but also prevent future damage from occurring. Hyperpigmentation (skin discoloration) – Hyperpigmentation is the darkening of an area of skin. Causes of hyperpigmentation range from sun damage caused by UV exposure, hormone fluctuations due to pregnancy or menopause, and skin injuries such as acne scarring. Certain skin types can also be more susceptible to hyperpigmentation. It is important to consult with a skin care professional prior to using products to even skin discoloration as high percentages of strong ingredients can cause further irritation and lead to more discoloration. Rosacea – Rosacea is a somewhat misunderstood skin condition. Currently, there is no known cure or cause. Rosacea is generally characterized by persistent redness and/or breakouts on the central areas of the face, commonly affecting the nose, cheeks, forehead and chin. Although there is no cure, there are many different methods of controlling rosacea symptoms. There are medical therapies that work well in conjunction with cosmeceuticals and professional treatments to control rosacea symptoms. Consult a physician for a diagnosis.
