Natural skin care
Natural skin care is the care of the skin using naturally derived ingredients (such as herbs, roots, essential oils and flowers) combined with naturally occurring carrier agents, preservatives, surfactants, humectants and emulsifiers (everything from natural soap to oils to pure water). The classic definition of
natural
skin care is based on using botanically sourced ingredients currently
existing in or formed by nature, without the use of synthetic chemicals, and manufactured in such a way to preserve the integrity of the ingredients.
As a result of this definition, many people who use natural skin care
products, generally make their own products at home from naturally
occurring ingredients. Many people use natural skin care recipes to make
remedies to care for their skin at home. Many spas and skin care salons now focus on using more naturally derived skin care products.
History
Natural skin care has its roots in the 4th millennium BC in Egypt with natural skin care treatments for a variety of skin conditions. One such treatment consists of bullock's bile, whipped ostrich eggs, olive oil, dough and resin mixed with milk. In the modern age many people with unique skin types and needs (sensitive skin, dry skin, oily skin) have turned to natural skin care solutions.
Some examples of natural skin care ingredients include jojoba, safflower oil, rose hip seed oil, shea butter, beeswax, witch hazel, aloe vera, tea tree oil,
and chamomile. Many of these natural ingredient combinations can be
tailored specifically to the individual's skin type or skin condition.
There is, however, no actual definition of
natural according to the U.S. Food and Drug Administration (FDA). All ingredients are chemicals by definition. "Derived" ingredients are
unnatural both according to the original substance and the method of derivation.
The term
natural has considerable market value in promoting
skin care cosmetic products to consumers, but dermatologists say it has
very little medical meaning and the FDA states the claim has no legal
meaning. Despite pressure from advocacy groups such as The Environmental
Working Group (EWG) the FDA has not defined what
natural is or
how to achieve it. Contrary to popular belief the FDA does not regulate
the sale of skin care and cosmetic products before they are sold.
The FDA recommends understanding the ingredient label and says "There
is no list of ingredients that can be guaranteed not to cause allergic
reactions, so consumers who are prone to allergies should pay careful
attention to what they use on their skin", further warning that "[t]here
is no basis in fact or scientific legitimacy to the notion that
products containing natural ingredients are good for the skin". Food
preservatives are commonly used to preserve the safety and efficacy in
these products.
Ayurvedic skin care
Ayurvedic
skin care is derived from medicinal practices that began over 5,000
years ago in India. Ayurvedic medicine and healing practices are based
on Indian philosophical, psychological, conventional, and medicinal
understandings. Ayurvedic approach to skin care is holistic and
considers the mind, body, and spirit together. Ayurvedas practices the
belief that there are three basic principles or humors born out of five
basic elements that exist in nature. These principles are known as Vata,
Pitta, and Kapha. These principles are believed to work together in
harmony to make up the entire body.
Ayurvedic skin types
In Ayurvedic skin care there are seven different types of
constitution that govern skin and hair types: Vata, Pitta, Kapha,
Vata-Pitta, Vata-Kapha, Pitta-Kapha, or Vata-Pitta-Kapha. Most people
fall into a combination of two of the three principles.
Ayurveda advises to modify one's diet, exercise, lifestyle and
supplements according to one's constitution of these three humors. Most
of the skin care products contain the following herbs—aloe vera, almond,
avocado, carrot, castor, clay, cocoa, coconut oil, cornmeal, cucumber,
cutch tree, emu oil, ginkgo biloba, ginseng, grape seed oil, ground
almond and wallnut shell, horse chestnut, witch hazel and honey.
Egg oil skin care
Egg oil
has many applications in skin care and can be used as an
excipient/carrier in a variety of cosmetic preparations such as creams,
ointments, sun-screen products or lotions where it acts as an emollient,
moisturizer, anti-oxidant, penetration enhancer, occlusive skin
conditioner and anti-bacterial agent.
As an occlusive agent, it protects against dehydration without
disturbing the pores and is easily incorporated in topical preparations
since it forms stable oil in water emulsions.
In Indian,
Japanese, Unani (Roghan Baiza Murgh)
and Chinese traditional medicine, egg oil was traditionally used as a treatment for hair care.
Honey skin care
Honey's natural antioxidant and anti-microbial
properties and ability to absorb and retain moisture have been
recognised and used extensively in skin care treatments as they help to
protect the skin from the damage of the sun's rays and rejuvenate
depleted skin.
Honey is also often used to treat acne, either dabbed directly on spots
or as a face mask, and has been used successfully to treat diabetic
foot ulcers.
Shea butter skin care
Shea butter is derived from the kernel of the "Karite" tree. Shea butter is known for its cosmetic properties as a moisturizer and emollient.
Jojoba skin care
Jojoba is used for skin care because it is a natural moisturizer for the skin. Jojoba is actually a liquid wax that becomes solid below room temperature, but is known as an oil.
Algae skin care
Polysaccharide derived from algae are natural moisturizers and can be used in cosmetics as humectants.Skin care treatments, for example Chlorella, uses such properties of algae to clean corneous cells, sebum, and remove pimples quickly.

Soap can be produced by mixing water and lye with olive oil castille soap
and also coconut oil to produce a natural and mild soap. A shampoo can
be produced by mixing water, with a mild surfactant such as decyl glucoside, a plant gum like xanthan gum as a thickener, salt, and emmolients such as coconut oil, vegetable glycerin, honey and essential oils. Natural surfactants include
Quillaja saponaria,
Acacia concinna or
Sapindus.Many other herbs have conditioner effects on the hair such as nettles or amla.
A body butter can be produced by mixing oils (such as a base of olive
and coconut oils) with beeswax. A natural body lotion can be produced by
mixing water and lecithin, cocoa or coconut butter, and dry oils such as grapeseed oil or thistle oil, beeswax, plant extracts such as witch hazel, calendula or aloe vera, hydrosols and essential oils.
A natural toothpaste can be made by mixing baking soda, glycerin and
water as a paste, with some antibacterial (e.g. sage) essential oils.
Natural preservatives is cosmetics are a controversial issue; these
might include vitamin E (only protects oil shelf-life, not against
bacteria or mold), rosemary oil, neem oil, tea tree oil, honey, propolis, salt, vinegar, lemon juice or green tea extracts, or by eliminating the use of water.
