While antioxidants have been used as active ingredients in skin care products for years because of their anti-aging abilities, effectively adding these natural ingredients to skin care products has its challenges. Advances in plant stem cell technology provide a new way to extract antioxidants from plants in their purest and most stable form, which can help products more successfully treat the signs of aging. Popular Botanical Antioxidants
Currently, there are a number of botanical antioxidants being used as ingredients in skin care products to improve the appearance of aging skin. Dermatologist Doris Day, MD, fellow of the American Academy of Dermatology, explains some of the properties unique to the following popular botanical antioxidants, but cautions that more research is needed to confirm these benefits are effectively provided through skin care products:
Plant Stem Cells Could Improve Anti-Aging Products
- Berry extracts from raspberries, blueberries and strawberries have become an area of intense research because they contain high levels of anthocyanins, a new category of strong antioxidants with anti-inflammatory abilities. Wild berries typically contain higher levels of the active ingredients than berries grown on farms.
- Soy is a rich source of isoflavones, which function as phytoestrogens (a group of chemicals found in plants that can act like the hormone estrogen). Topical estrogens have been found to increase skin thickness and promote collagen production.
Scientists have noted that plants have evolved over time to protect themselves from the damaging effects of oxidation (the main cause of skin aging in humans), which occurs following sun exposure, and they are trying to apply this concept to skin care products. Currently, antioxidants found in certain plants are included in many anti-aging skin care products, but the plant materials are taken from plants grown outdoors and, as a result, can contain contaminants such as pesticides, heavy metals and fungal toxins.
New research is focusing on how to use plant stem cells to eliminate the contaminants from the plant and control the concentration of ingredients in the plant. Stem cells contain a purer and more consistent level of antioxidants that can be extracted and added to anti-aging products. Dr. Day’s Skin Care Tips
- Practice proper sun protection daily by using a broad-spectrum sunscreen with an SPF of 30 or greater, seeking shade, and wearing protective clothing.
- Exfoliate the skin to improve a dull appearance. The frequency of exfoliation depends on skin type (e.g., dry skin should be exfoliated less frequently, as it is important not to over-strip the skin of its protective outer layer). It is especially important to wear sunscreen and/or protective clothing after exfoliating because it makes the skin even more vulnerable to sun damage.
- Eat foods rich in antioxidants, which can help protect against premature aging and skin cancer. For example, a Mediterranean diet that contains foods such as olive oil, fruits, vegetables, and nuts provides more antioxidants compared to a diet based largely on processed foods.
- The old adage “beauty comes from within” still holds true, as the skin reflects a healthy body and mind at any age.
- If you are concerned about aging skin, see a board-certified dermatologist for advice tailored to your skin type.
