If you were to compare skin care products and ingredients of a retail store to that of a professional line, you would realize that some products are better than others.
The main difference between a cosmetic product from a pharmaceutical is that the cosmetic’s ingredients will remain on the surface of the skin and the pharmaceutical will penetrate.
Active ingredient defined by
Milady’s Skin Care and Cosmetic Ingredients Dictionary, is an ingredient with “
treatment value.” When placed on the skin, it would perform a therapeutic or beneficial function such as healing, hydrating, soothing, and toning.
Ingredients can be derived from plants, vitamins, or animals, and are also synthesized from chemicals. A preservative is an inactive ingredient which is necessary to the product formulation. What allows products to spread, gives them body and texture, and a specific form such as a lotion, cream, or gel are the functional ingredients.
Active ingredients are sometimes called
performance ingredients. They are used in prescription-only products and cause the actual changes in the appearance of the skin.
Examples: glycerin which hydrates the skin surface; alphahydroxy acids
AHAs which exfoliate the corneum; and
lipids which help patch the skin’s barrier.
Use of an Active Ingredient
We choose active ingredients according to our skin type. When using the right active ingredient in the appropriate form such as solution, serum, cream, lotion, or ointment, the result of the product becomes evident.
“Sometimes you will need to use more than one active ingredient; the synergistic mechanism of two or more active ingredients can often increase efficacy and results” said
Dr. Neal B. Schultz author of
It’s Not Just About Wrinkles. He goes further to say, “When using more than one active ingredient, begin with the product that is in the lightest form. A lighter product will never penetrate a heavier product.”
First: Use water or alcohol-based products;
Second: solutions, serums, or lotions;
Third: creams;
Last: petroleum-based products.
In Away With Wrinkles, author and dermatologist Dr. Nicholas Lowe, clarifies what to look for in the active ingredients of creams:
- Moisturization from humectants such as glycerine or sodium hyduronate
- Antioxidant mixtures, e.g. vitamin E (tocopherols), vitamin C (ascorbic acid, ascorbyl palmitate)
- Low levels of retinoids, such as retinal, retinaldehyde, and vitamin A
What about Cosmeceuticals?
Cosmeceuticals are products intended to improve the skin’s health and appearance. They are scientifically designed topical products that meet chemical, pharmaceutical and medical standards but they do not change the structure and function of the skin. In other words, they are not classed as pharmaceutical prescription creams. They contain ingredients that influence the biological function of the skin. Cosmeceuticals improve appearance, and they do so by delivering nutrients necessary for healthy skin (e.g. neither too dry nor too greasy.)
Dermatologist Patricia K. Farris, MD, FAAD, clinical associate professor of dermatology at Tulane University School of Medicine in New Orleans states:
“Cosmeceuticals are divided into three categories based on their active ingredients:
- Anti-oxidants can reduce the harmful effects of free radicals, which are molecules that injure the skin's cells, causing inflammation, increasing sun damage and contributing to the development of skin cancer.
- Peptides are smaller proteins that stimulate the production of collagen and thicken the skin.
- Growth factors are compounds that act as chemical messengers between cells and play a role in cell division, new cell and blood vessel growth, and in the production and distribution of collagen and elastin.”
Dr. Patricia Farris recommends:
For day, wear sunscreen and consider also using products containing anti-oxidants, as they have sun-protection properties. At night, use products containing retinoids, peptides or growth factors for their repair properties.
