Spa Words and Definitions


What are Essential Oils? An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils, ethereal essential oils from Yon-Kaoils or aetherolea, or simply as the "oil of" the plant from which they were extracted, such as oil of clove. An oil is "essential" in the sense that it carries a distinctive scent, or essence, of the plant. Essential oils do not form a distinctive category for any medical, pharmacological, or culinary purpose.

Essential oils are generally extracted by distillation. Other processes include expression, or solvent extraction. They are used in perfumes, cosmetics, soaps and other products, for flavoring food and drink, and for adding scents to incense and household cleaning products.

What causes Acne? Acne vulgaris (or cystic acne) is a common human skin disease, characterized by areas of skin with seborrhea (scaly red skin), comedones (blackheads and whiteheads), papules (pinheads), pustules (pimples), Nodules (large papules) and possibly scarring. Acne affects mostly skin with the densest population of sebaceous follicles; these areas include the face, the upper part of the chest, and the back. Severe acne is inflammatory, but acne can also manifest in noninflammatory forms. The lesions are caused by changes in pilosebaceous units, skin structures consisting of a hair follicle and its associated sebaceous gland, changes that require androgen stimulation.
Acne occurs most commonly during adolescence, and often continues into adulthood. In adolescence, acne is usually caused by an increase in testosterone, which people of both genders accrue during puberty. For most people, acne diminishes over time and tends to disappear — or at the very least decrease — by age 25. 
  What causes acne and what can be done to bring it under control is a dialogue you should be having with your esthetician first and your dermatologist second because the most effective measures can be natural rather than prescriptions. A wholistic and heathy remeday can simply be consistant regimeat home with natural products.

 What is Rosacea? Rosacea is a chronic condition characterized by facial erythema (redness). Pimples are sometimes included as part of the definition. Unless it affects the eyes, it is typically a harmless cosmetic condition. Treatment in the form of topical steroids can aggravate the condition.
  Rosacea primarily affects Caucasians of mainly north western European descent and has been nicknamed the 'curse of the Celts' by some in Britain and Ireland, but can also affect people of other ethnicities. Rosacea affects both sexes, but is almost three times more common in women. It has a peak age of onset between 30 and 60.
  Rosacea typically begins as redness on the central face across the cheeks, nose, or forehead, but can also less commonly affect the neck, chest, ears, and scalp. In some cases, additional symptoms, such as semi-permanent redness, telangiectasia (dilation of superficial blood vessels on the face), red domed papules (small bumps) and pustules, red gritty eyes, burning and stinging sensations, and in some advanced cases, a red lobulated nose (rhinophyma), may develop.

What is a facial? A facial is a procedure involving aEclat Cocoon 3 variety of skin treatments, including: steam, exfoliation, extraction, creams, lotions, facial masks, peels, and massage. It is normally performed in a facial spa.

What is a Mask? A facial mask is a creamy paste (or gel)or a sheet applied to the entire, already-cleansed face. Facial masks often contain minerals, vitamins, essential oils, and/or fruit extracts (e.g., cactus, cucumber, etc.). There are different kinds of masks for different purposes: deep-cleansing, by penetrating the pores; healing acne scars or hyper-pigmentation; brightening, for a gradual illumination of the skin tone. Some masks are designed to dry or solidify on the face, almost like plaster; others just remain wet. The perceived effects of a facial mask treatment include revitalizing, healing, or refreshing; and, may yield temporary or long-term benefits (depending on environmental, dietary, and other skincare factors).Yonka Mask  Masks are removed by either rinsing the face with water, wiping if off with a damp cloth, or peeling off of the face by hand. Duration for wearing a mask varies with the type of mask, and manufacturer's usage instructions. The time can range from a few minutes, to, overnight. Those with sensitive skin are advised to first test out the mask on a small portion of the skin, in order to check for any irritations.

What is Dehydration? Dehydration of skin and mucous membranes can be called medical dryness.
There are three types of dehydration: hypotonic or hyponatremic (primarily a loss of electrolytes, sodium in particular), hypertonic or hypernatremic (primarily a loss of water), and isotonic or isonatremic (equal loss of water and electrolytes). In humans, the most commonly seen type of dehydration by far is isotonic (isonatraemic) dehydration which effectively equates with hypovolemia, but the distinction of isotonic from hypotonic or hypertonic dehydration may be important when treating people who become dehydrated.
  Physiologically, dehydration, despite the name, does not simply mean loss of water, as water and solutes (mainly sodium) are usually lost in roughly equal quantities to how they exist in blood plasma. In hypotonic dehydration, intravascular water shifts to the extravascular space, exaggerating intravascular volume depletion for a given amount of total body water loss. Neurological complications can occur in hypotonic and hypertonic states. The former can lead to seizures, while the latter can lead to osmotic cerebral edema upon rapid rehydration.

What is an Anti-Oxidant? An antioxidant is a molecule capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons or hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions. When the chain reaction occurs in a cell, it can cause damage or death to the cell. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid, or polyphenols.
In the lab, rosemary has been shown to have antioxidant properties. Antioxidants can neutralize harmful particles in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death.
  Also in the lab, rosemary oil appears to have antimicrobial properties (killing some bacteria and fungi in test tubes). It isn't known whether rosemary would have the same effect in humans.

What is Anti-inflammatory? Anti-inflammatory refers to the property of a substance or treatment that reduces inflammation. Anti-inflammatory drugs make up about half of analgesics, remedying pain by reducing inflammation as opposed to opioids, which affect the central nervous system.
What are the benefits of a Facial? A facial is a skin treatment that many spas offer, typically performed on patrons by a licensed esthetician. A facial can benefit both the look and the feel of the face. It is also a relaxing way to give yourself an extra special treat. Cleansing Getting a facial thoroughly cleanses the skin. The massage, along with the gentle cleanser, goes deep into the pores to lift away dirt and oil. Having this done on a regular basis can help keep pores from becoming clogged and may even prevent potential acne breakouts.
  Exfoliating: Another benefit of a facial is the exfoliation of dead skin cells. The skin gradually sheds these cells on its own over time. However, a facial gets rid of all the dead skin quickly and thoroughly.
  Circulation: A facial can improve the circulation of the skin on the face. If you suffer from poor circulation, you may find that any numbness and tingling in the face decreases after getting facials on a regular basis. Facials can also help to improve your complexion by decreasing the skin's red, ruddy appearance that may come from poor circulation.
  Premature Aging Facials: These can also help fight the effects of premature aging by keeping the skin hydrated and looking healthy. When skin is no longer dry from dehydration, it can slow down the aging process substantially.
  Determining Proper Skin Care: Having a facial performed by a professional esthetician is a good way to find out which products you should use on your skin. It's easy to use the wrong products, and a trained esthetician can help guide you. Your skin may look and feel oily, for example, but it may actually have some dry patches that require a moisturizer to balance its surface. A skin care specialist can help you choose the right products to ensure that your skin is in its best condition.
  Relief of Stress: Getting a facial is a wonderful way to relieve stress. It helps relax the skin as well as the entire body. Stress can wreak havoc on the complexion and cause unsightly breakouts. Having a facial done at least once a month, can prevent this and can give you a chance to feel pampered. - MerchantCircle.com

Chemical compounds that occur naturally in plants (phyto means "plant" in Greek), are responsible for color and organoleptic properties, such as the deep purple of blueberries and smell of garlic. The term is generally used to refer to those chemicals that may have biological significance but are not established as essential nutrients. Scientists estimate that there may be as many as 10,000 different phytochemicals having the potential to affect diseases such as cancer, stroke or metabolic syndrome. Although certain phytochemicals are available as dietary supplements, some scientists speculate that potential health benefits of phytochemicals may best derive from consumption of whole foods.

What is Clarifying? There are two ways to clarify the complexion : by improving the elimination of dead cells, by improving the oxygenation and the coloration of the melanin in the superficial layers of the epidermis.

What is Exfoliation? Exfoliation involves the removal of the oldest dead skin cells on the skin's outermost surface, and has been used for many years to help maintain skin. Exfoliation is involved in the process of all facials, during microdermabrasion or chemical peels at medical spas. Exfoliation can be achieved through mechanical or chemical means.
