What is Natural Skin Care?
Natural skin care is normally understood to refer to those products characterised by the absence of synthetic ingredients, such as preservatives, petrochemical derivatives, mineral oils, fragrances and harsh detergents.
Typically, natural skin care products are made using natural ingredients such as plant oils, essential oils, herbal and floral extracts (both aqueous and waxy), that have been prepared in the “old fashion way”, without chemical processing or modification. Sometimes, ethically produced animal derivatives, such as beeswax, may also be present in natural skin care (1).
Natural skin care made with approved organically produced raw materials and practices can be organic certified by the relevant organic organizations.
Unfortunately, there are numerous products in the market that claim to be either natural or that are cleverly marketed for their singular botanical extract or vitamin, amongst a dense cocktail of synthetic ingredients. These are the “pseudo-natural” products (1). To help clarify if a skin care product is really natural, it is recommended to read the ingredients section in the label.
Why is natural skin care better than synthetic?
Products that are made from ingredients that have been extracted naturally from sustainably maintained plants and crops manifest the essence, the energy, the qualities and the benefits of the source raw material, in ways that synthetics ingredients do not.
Simply put, the geographical location, the soil and the water the plants are grown in, as well as the sun exposure, the seasons and harvesting times contribute to the mature plants and crop yields in unique ways. Ekologisk solskydd
These factors cannot be mimicked in the laboratory or controlled nurseries, as the natural exposure to the environmental conditions facilitates development of subtle differences in the plants. These are then reflected in the quality of the extracted oils, as well as on their specific composition, properties and benefits.
Besides, synthetic ingredients are produced in laboratories using scientific, yet often hazardous processes involving the use of carbon dioxide, propylene glycol or hexane based methods. Although these chemical agents may only be present is trace amounts in the final synthesised ingredients, it is unclear what effect they might have as they accumulate in our bodies, over a prolonged period of exposure (2).
Of course, some of the natural extracts and oils may also be affected or destabilised by the natural extraction methods used in their preparation. For these reasons manufacturers of natural skin care products give great consideration to the sourcing of their raw materials and how natural ingredients are prepared from the latter.
What is Special About Plant Oils?
Plant oils are made up of complex mixtures of different fatty acids (lipids). It is the specific mix and ratio of these fatty acids that determines the unique character of any oil. In addition to the main lipid fraction, there are also other very important bioactive substances such as the phospholipids, phosphatides, phytosterols, phytoestrogens, isoflavones and vitamins. These bioactives are known as the unsaponifiable fraction of the oil. They normally are present is small amounts and are unique signatures of the oils (3).
