ANTIPERSPIRANT VS DEODORANT
Deoderants are cosmetics formulated to mask body odor, to make the skin smell better. They commonly contain odor-masking fragrance. They can be formulated as aerosols and sprays, pumps, roll-ons, solid sticks, gels and creams. Deoderants do not prevent sweating. Antiperspirants are over-the-counter drugs, regulated by the US Food and Drug Administration (FDA). They are usually formulated with aluminum-based compounds with the intent on preventing sweat from reaching the skin surface by creating a temporary plug within the sweat duct. All sweat is odorless until it combines with bacteria found on the skin surface. By preventing perspiration, antiperspirants are also deoderants.
DO I NEED A TONER?
Toner, the skincare product that is as varied in formulation as is the list of their alleged benefits. The benefits touted by health and beauty magazines for toners are endless. They supposedly cleanse, shrink pores (note: like the length of your arms, pore size does not change), remove dirt, pollen, and pollution, hydrate, soothe and calm, repair, balance the skin's pH, nourish, stimulate blood circulation, function as an antibacterial, clear blemishes, and more.
Toners can be sprayed on, dabbed on with a cotton ball, applied with guaze or a washcloth, or with the fingers. Some are used with water, some without.
Toners come without alcohol, these claim to "refresh." They come with little alcohol (up to 20%), also known as tonics, not to be confused with the traditional quinine containing carbonated beverage. And they can be formulated with a high percentage of alcohol (20-60%), also called an astringent or drying agent, which may cause redness, irritation, or burning in individuals with sensitive or normal skin.
Want to cleanse the skin? Use a mild soap-free cleanser. Want to hydrate the skin? Apply a well-formulated moisturizer. Have oily or acne-prone skin, see a dermatologist. Skip the toner!
WHY FINGERTIPS WRINKLE
Did you ever wonder why the tips of the fingers wrinkle like a prune when exposed to water for a long period of time? People often think that osmosis causes water to enter the outer layer of skin making the fingertips swell. But since the 1930's, scientists have known that fingertips don't swell or wrinkle when there is nerve damage to the fingers, even with prolonged submersion in water.
So if it's not osmosis, what causes this phenomenon? A recent study may give us an answer. Mark Changizi, an evolutionary neurobiologist at 2AI Labs in Boise, Idaho, and his colleagues, propose that wrinkling of the fingertips has an evolutionary function. That our nervous system, by causing vasoconstriction of blood vessels below the skin, is responsible for this involuntary reaction that offers an advantage in gripping wet objects.
The study demonstrated that wrinkled fingertips make it easier to grasp objects underwater. Participants in the study had to move dry and wet objects with both dry fingertips, and again, with wrinkled fingertips. The results showed that participants were able to move wet objects 12% faster with wrinkled fingertips than with dry ones. But wrinkled fingertips made no difference when it came to moving dry objects. Basically, when the pads of the fingers are wrinkled, they provide a better grip in wet conditions, like treads on a car tire that increase the surface area of tire on the road.
So why do our fingertips wrinkle when in water? Our brain causes this evolutionary trait to enhance the gripping ability of the fingers underwater! Perhaps this was beneficial to our ancestors who might have had to gather food from wetlands and streams.
And if it happens to you, don't worry, it goes away all on its own. Skin is truly an amazing organ!
"NATURAL" ISN'T BETTER
A growing number of consumers are opting for "natural" skincare products. The media loudly and aggressively sends the message the "natural skincare products are good and synthetic products are bad". They imply that standard facial moisturizers and cleansers are filled with poisonous cancer-causing chemicals. As a result, many people understandably opt for "natural" skincare items that seem "better". In truth, the term "natural" found on skincare product labels is simply an example of brilliant marketing.
The term "natural" on personal care products has no specific definition. The U.S. Food & Drug Administration (FDA) has not defined the term nor has it established any standards or regulatory guidelines for its use on skincare product labels. In addition, cosmetic companies are not required to prove these "natural" products live up to their claims. In fact, the FDA warns, "There is no basis in fact or scientific legitamcy to the notion that products containing natural ingredients are good for the skin."
"Natural" ingredients may imply where the ingredients come from but discloses nothing about the safety of the ingredient. A plant-based product is not necessarily healthy. While most consumers can apply personal care products that claim to be "all natural" without any ill effects, some plant-derived ingredients can cause severe reactions in those with allergies. Tea tree oil, lavender, chamomile and its related family plants, including daisies and ragweed, are commonly used in "natural" skincare products and may cause an allergic reaction in susceptible individuals. Additionally, exposure to natural oils like bergamot, lavender, musk, and citrus compounds from lemons and limes also frequently used in natural products may cause an increased sensitivity to the sun's harmful ultraviolet rays.
As for the claims that synthetic ingredients, those "bad" chemicals, cause cancer: poor scientific studies and the need to sell beauty magazines that rely on sensationalism consistently find cancer links that simply don't exist. Whether a chemical, "natural" or synthetic, causes cancer or any other toxic reaction depends on the dose of the chemical, not the chemical itself. Almost every chemical has a dose below which no adverse effect or harm can occur. (See DOSE VS TOXICITY)
Still, plant-based products remain popular. Whether just folklore, or the influence of the beauty industry and advertising media, many consumers definitely prefer to purchase "natural" skincare products formulated with plant-based ingredients. It's true, plants are a huge reservoir of potentially beneficial compounds. However, few studies, if any, demonstrate they are beneficial to humans. A plant-derived ingredient isn't necessarily good for you, nor is a synthetic ingredient necessarily toxic.
SUNBURN: DOs & DON'Ts
You put on your sunscreen, but clearly not enough. Maybe you missed a spot, or maybe just forgot the sunscreen altogether. Your skin is red and painful. It feels hot to the touch. You have it, sunburn!
· Stay out of the sun to prevent further damage.
· Take a pain reliever. A nonsteroidal anti-inflammatory drug like Advil or Motrin will relieve some of the discomfort and swelling.
· Cool the skin with frequent cool compresses or take a cool shower or bath.
· Moisturize. Sunburned skin loses water into the environment so apply cool aloe gel or moisturizing lotion to healing skin.
· Apply an over-the-counter hydrocortisone cream (0.5-1%) to minimize inflammation, redness and itching.
· Drink water. Sun exposure and sunburn causes water lose through the skin. Stay hydrated.
· Apply antibiotic cream and a wet dressing to blisters should they develop.
· Get medical attention should fever, nausea or other systemic symptoms arise.
· Get more sun.
· Break any blisters if they should develop. This increases the risk of infection.
· Apply lidocaine or other “caine” anesthetics as they may cause allergic skin reactions
