Natural skin care using topical creams and lotions made from materials available in nature. Many literature has recently reviewed plant-derived ingredients, which may include herbs, roots, flowers and essential oils, but natural substances in skin care products include animal products such as beeswax, and minerals. This substance can be combined with various carrier agents, preservatives, surfactants, humectants and emulsifiers.
There is no legal definition in the US for "natural" or "organic" advertising terms when applied to personal care products. Consumers often express preferences for leather products with organic and natural ingredients. The personal skin care market based on natural products has shown strong growth. Clinical and laboratory studies have identified activities in many natural ingredients that have activities that are beneficial for personal skin care, but there is a lack of convincing evidence for the efficacy of natural products in medical problems.
Some natural products and therapies may be harmful, good for the skin or systemic. People who are susceptible to allergies should pay close attention to what they use on their skin. Dermatologists may feel that there is enough scientific evidence to assist in the selection or avoidance of certain natural ingredients.

Many countries require the composition of registered skin care products on the product, using the Convention on International Nomenclature of Cosmetic Ingredients (INCI). The ingredients are listed in the order of their percentages in the product; Natural ingredients listed in Latin and synthetic materials are listed under the technical name. "The US government has documented more than 10,500 ingredients in cosmetic products, but only a small fraction of these chemicals have been tested for safety, and of those tested, some have been identified as carcinogens, teratogens (causing births). defects), and reproductive toxicity (impairs ability to reproduce). "
The FDA surveyed 1,687 consumers age 14 and older in 1994 about their cosmetic use. Almost half of these consumers feel that a product that claims to be "natural" must contain all natural ingredients. However, although the United States Department of Agriculture (USDA) has established in certain terms within the special regulatory region for organic products, the US Food and Drug Administration (FDA) does not recognize the definition for natural products. Therefore, there is no legal definition in the US for "natural" or "organic" advertising terms in personal care products. The FDA prohibits certain ingredients in cosmetics.
Some organic products that are set organic may be highly modified, sometimes much more than conventional products.

History
Plant and herbal extracts have been used by many cultures as cosmetics and perfumes since ancient times.
Scientific research assesses natural products, selected based on experience in the ancient era. Validated use of these materials and products awaits further assessment.
Cosmetics
Consumer preferences
Consumers often express preferences for leather products with organic and natural ingredients. The skin care market based on natural products has shown strong growth. Clinical and laboratory studies have identified activities in many natural ingredients that have activities that benefit the skin. Dermatologists may feel that there is enough scientific evidence to help the selection of certain natural ingredients.
Consumers expect products to appear as advertised.
Industry response
Voluntary discontinuation of precursor substances that release small amounts of formaldehyde, which are carcinogens, and reduce the potential level of carcinogenic 1,4-dioxane impurities. The polycyclic musical ingredients, which have raised concerns as persistent and bioaccumulative endocrine disruptors, are being discontinued.
Alternative medicine
There are significant reservations about complementary and alternative medicine (CAM) including "lack of evidence that supports CAM's efficacy and safety" for skin problems. However, patients expressed a desire to use natural ingredients as a treatment. The literature search found an increased prevalence of CAM use for skin conditions. A number of textbooks deal with CAM skin care perspective. The purpose of this section is to review the botanical compounds in skin care; a broader overview of the history and theory behind other CAM modalities such as psychokutan therapy, acupuncture, and homeopathy can be found in recent reviews.
Western
The plant monograph with the dermatological relevance of the German E Commission has recently been reviewed.
According to Baumann, "Botanical compounds used for dermatology and cosmetic applications include: olive oil, chamomile, colloid oatmeal, wheat kernel extract, feverfew, acai berry, coffee berry, curcumin, green tea, pomegranate, licorice, mulberry paper, arbutin, and soybeans. "Many of these botanical sources offer biologically active components that require in vitro and in vivo inquiry further".
A review of 35 plant families found that "various phytomolecules, especially from polyphenols, triterpenes and sterol classes, exhibit promising activity."
Colloidal oatmeal may be helpful in psoriasis. Aloe vera may be helpful in atopic dermatitis. In both of these conditions, the benefits may arise from the anti-inflammatory properties. "To combat acne and rosacea, green tea, niacinamide and feverfew are considered efficacious.For hyperpigmentation and antioxidant abilities, licorice, green tea, arbutin, soy, acai berry, turmeric and pomegranate are among the plants and compounds found most beneficial. necessary to determine to confirm and explain the benefits of these ingredients in the prevention and management of skin diseases. "
Assessment of clinical trials on the preparation of green tea and its use in dermatology find some evidence for potential benefits.
Ayurveda
Ayurvedic skin care comes from a treatment practice that began more than 5,000 years ago in India. Ayurvedic medicine and healing practices are based on Indian philosophical, psychological, conventional, and Indian understanding. Most ayurveda skincare products contain the following ingredients - aloe vera, almonds, avocados, carrots, distances, clay, cocoa, coconut oil, cornmeal, cucumber, cutch tree, emu oil, ginkgo biloba, ginseng, grapeseed oil, almond and walnut soil, horse chestnut, witch hazel and honey.
The Ayurvedic approach has been used in molluscum contagiosum, lymphatic filariasis, vitiligo and lichen planus.
Phyllanthus emblica (amla, Indian gooseberry) has been used in ayurvedic medicine. Phyllanthus emblica standard extracts have long-lasting and broad-spectrum antioxidant activity. It may be suitable for use in anti-aging skin care products, sunscreen and general purpose.
Traditional Chinese Medicine
Materials
Natural skin care ingredients include jojoba, safflower oil, pelvic rose oil, shea butter, beeswax, witch hazel, aloe vera, tea tree oil, coconut oil, and chamomile.
- Egg oil can be used as an excipient/carrier in various cosmetic preparations such as creams, ointments, sunscreen products, or lotions. In India, Japan, Unani (Roghan Baiza Murgh) and traditional Chinese medicine, egg oil is traditionally used as a treatment for hair care.
- Jojoba is used for skin care as it is a natural moisturizer for the skin. Jojoba is actually a waxy liquid that becomes solid under room temperature, but is known as oil.
- Shea butter comes from the shea tree kernel ( Vitellaria paradoxa ). Shea butter is known for its cosmetic properties as a moisturizer and emollient.
Research
Dermatological studies have shown that the bioactive materials used in cosmeceuticals have benefits beyond traditional moisturizers (eg, Chen et al., 2005; Zettersten, Ghadially, Feingold, Crumrine, & Elias, 1997). However, despite reports of the benefits of some cosmeceutical products, there is no formal requirement to prove that these products meet their claims.
Natural compounds that are friendly to biocompatibility and environmentally friendly have the potential to provide materials with photoresistant and thermoresistant properties.
Dehydroabietic acid (DAA), a naturally occurring resin acid, "has an effect of prolonged life in Caenorhabditis elegans, prevents the accumulation of lipofuscin, and prevents collagen secretion in human dermal fibroblasts.We found that the anti-aging effect is primarily mediated by activation of SIRT1. "DAA may activate the enzymatic activity of SIRT1, which may have a preventive effect on the aging process.
Validated use of these materials and products awaits further assessment.
Related products
Cosmeceuticals is a topically applied combination product that unites cosmetics and "biologically active ingredients." Similar products in perceived but verbally digested benefits are known as nutricosmetics. According to the United States Food and Drug Administration, the Food, Drug and Cosmetics Act "does not recognize categories such as" cosmeceuticals. "A product may be a drug, a cosmetic, or a combination of both, but the term" cosmeceutical "has no meaning under the law ". Medicines must go through an intensive examination and approval process by the FDA. Cosmetics, and related products, although regulated, are not approved by the FDA before being sold.
Caution
Some alternative and natural products and therapies may be harmful, whether for skin or systemic.
The FDA recommends to understand the ingredients label and says "No list of ingredients can be guaranteed not to cause an allergic reaction, so consumers who are susceptible to allergies should pay close attention to what they use on their skin", further warning that "[t] here there is no basis or scientific legitimacy for the idea that products containing natural ingredients are good for the skin ". Food preservatives are generally used to maintain the safety and efficacy in these products. Alternative treatment may increase the prevalence of eczema. Bhuchar recommends that "edible substances including most homeopathic, Ayurvedic, and Chinese traditional herbs not regulated by the US FDA should be viewed with caution because they can cause severe side effects" such as arsenic poisoning and liver failure. "
Given the lack of evidence for the efficacy of natural skin care, if applied may often need to be used in combination with conventional treatment, rather than independently.
According to Bhuchar, there is a consensus in the literature that dermatologists need more information about CAM. Wu suggests that "dermatologists should be aware of what the patient might use and can advise him about the efficacy of these ingredients or potential side effects". Many patients fail to tell their doctors about the use of herbal ingredients. There are a number of reasons for this.
