The
cosmetics industry is constantly striving to produce the most
innovative products and effective market for skin care, tempting us to
buy the essence of dreams miracles in jars.
Antioxidants
However, since all products are specifically designed to make us look
younger longer, the consumer faces a bewildering array of products
attractively packaged prompting questions like:
- How to choose? (Those unpronounceable names)
- What ingredients?
- What effect?
- Are they safe?
- What is the evidence to support the claims / complaints against companies?
- Would you care about these claims?
- You decide how the prices?
Facial creams have several standard components:
As with most things in life, you get what you pay for. Cheap cosmetic products likely to contain cost components.
In the case of expensive brands, usually paid by the promise that the
new component X will provide anti-aging, hydration, anti-wrinkle,
firming skin, and some other benefit of the many that exist.
The components are fashionable as soon as they pass. Cosmetics companies seem to be interested only in the most modern and best-selling. Multiple resources to develop components that make the most effective products for skin that are never used.
Thus, the research provides a slight advantage to companies but quickly
copy innovation, adapts and plays a wide range of qualities and prices
in the cosmetics market.
In addition, the cosmetic companies strive to find new and effective ways to get ingredients for the skin. Liposomes are often used.
Are tiny capsules filled with active ingredients that are absorbed
through the skin releasing their contents precisely in places where they
are needed most: beneath the surface, in the deeper layers of the skin.
Dermatologists say that cosmetics in general can achieve little; at best a temporary hydration. By definition, a cosmetic is not authorized to alter the structure or function of the skin. Of course, many companies suggest that their products alter the skin. These are surpassing the boundary between cosmetics and therapeutic. The laws are constantly changing and are not the same for all countries, so many of these products are subject to supervision. For this reason, the public is often misinformed and confused.
- Preservatives: as essential oils or synthetic parabens, including ethyls, propyls or butyl.
- Emulsifiers: linolenic acids as are commonly used to ensure uniform and consistent mix.
- Humectants: (hold water), such as glycol or glycerol. They are often used mineral oil derivatives extracting water from the air to the skin surface and in turn prevent the product from losing water and drying.
- Silicone: it is often incorporated to provide a pleasant texture and make the application easier

Also known as AHAs. They have revolutionized the effectiveness of many products.
Its properties have been known since Roman times, and the first
scientific papers dating from 1974. As a group, no other cosmetic
ingredients that have been studied that AHAs. Citric acid include citrus fruits, apples malic acid and lactic acid in milk. However, the most widely used and researched (by far) is glycolic acid, which comes from sugar cane.
At low concentrations, they act as exfoliants, unlikely to irritate the skin.
The highest concentrations are used in cosmetic or dermatological
clinical consultations, proving to be effective in reducing the signs of
aging, and are helpful for treating acne and excess pigmentation.
Importantly, the application of high concentrations of AHAs should be
done under medical prescription and together with a sunscreen.
Ascorbic acid
This is the chemical name that names the basic molecule of vitamin C . The derivatives of pure vitamin C are unstable and very irritating. Vitamin C is a powerful antioxidant with a great ability to lighten pigmentation; for this reason it is the most common component of current products.
Beta hydroxy (BHA)
The most common BHA is salicylic acid.
The BHAs are anti-inflammatory and exfoliating, very useful for the
treatment of pimples agents, but may cause hypersensitivity reactions if
abused.
Amino Acids
Forming substances and proteins that are present in the skin and hair. The theories that can be absorbed through the skin to rehydrate and provide nutrients are unproven.
Every breath we do involves the formation of free radicals that damage healthy cells. This results in skin wrinkles and loss of skin tone. Antioxidants can reduce free radical activity thereof. So in theory, antioxidants can help the body repair itself. Currently, there is no evidence to the contrary and there are many products that contain antioxidants. Look for vitamins A , C and E and Pycnogenol, the active part of the extract of grape seed.
Caviar
Some theories that put caviar on the skin rejuvenates are for innocent people and too credulous.
ceramides
One component is rumored skin. Again I must say that there is no scientific support for this theory despise. Ceramides can be effective in the future.
Co-enzyme 10
It is also a component of fashion. It is found in the skin and is an antioxidant and antibacterial agent. As we turned years, levels of Q10 decrease and may influence the aging of skin. Theories Q10 anti-aging properties are unsubstantiated.
Collagen
It is a very large molecule and there is no scientific evidence to affirm the idea that can penetrate the skin. It can only be placed on the surface where it produces few benefits.
Green tea
It contains polyphenols that have antioxidant and anti-inflammatory. It is a very popular component and can be found in any of the depilatory creams or waxes. These effects may explain why cold tea bags applied on the face to reduce inflammation in the eye. Do not dismiss the idea of tea bags as research promises!
Hyaluronic acid
It is an essential protein found in the skin. It has enormous moisturizing properties, able to attract about 100 times its weight in water. However, to be active, hyaluronic acid needs to be in the correct concentration.
Lanolin
It is obtained from wool and used as a barrier to reduce water loss from the skin surface. It is a common cause hypersensitivity therefore have to carefully read the list of components.
Parabens
They are present in foods and cosmetics to prevent the growth of bacteria and fungi. They are not toxic and are approved by the authorities.
Polyethylene glycol (PEG)
It helps spread the product evenly on the skin.
Retinoic acid, retinol or retinyl palmitate
They are derivatives of vitamin A. Retinoic acid has convinced the
medical profession that a topically applied cream can actually reduce
the appearance of wrinkles and pigmentation. Under the trade name Retinova, this is the first drug licensed to treat sun-damaged skin.
Of course, for such a license the company has to prove beyond any doubt
that the product takes effect in most people with limited side effects. However, it can irritate the skin and make more sensitive to the sun so you should use a sunscreen. Cosmetics companies have jumped on the bandwagon quickly with various derivatives of vitamin. Most have limited benefits for the skin and none is as effective as Retinova.
Squalene
It is another fatty component of the skin, which helps maintain the barrier function thereof and flexibility.
Tocopherol acetate
Vitamin E is a powerful antioxidant and anti-inflammatory agent. Often this vitamin is included in sunscreens to fight against free radicals produced by sunlight. It is collecting accurate information on the benefits of topical and oral vitamin E in the skin aging.
Active ingredients
This is the common name. Some of the most recent are:
This list of components is not surprising that most people feel
insecure when it comes to choosing the right product to protect your
skin. Therefore, the next time you choose a facial or body product, seek the advice of a dermatologist. They have powerful products in their arsenal, they are usually more effective than cosmetics found in stores. Look at the components of the product and feel free to ask.
