7 Surprising Skincare Myths and Facts

If you Google “skincare advice,” you'll find tips on everything from avoiding wrinkles to getting rid of acne. Most of it looks pretty convincing and it can be hard to find the real truth.

If you want to tell fact from fiction, go to the science. Here are 7 common skincare myths and facts and the data that either supports or debunks them. 

#1: Too Much Sugar Can Age Your Skin Faster

Fact. Sugar consumption doesn't have as dramatic an effect on skin aging as some other factors, such as genetics or sun exposure, but it can speed the aging process. Sugar damages the fibers that give skin its elasticity and this leads to more wrinkles and saggier skin. [1]


Eating too much sugar can actually jump-start a process that makes you look older. These foods lead to a blood sugar spike that causes the production of compounds known as advanced glycation end products, or AGE's. As a person gets older, AGE's build up in the body and accelerate the effects of aging. [2]  

#2: Beauty Sleep Works

Fact. Observational data has shown that people who get plenty of rest report having fewer wrinkles, less acne, and better overall skin tone.

During non-REM sleep, your body releases anti-inflammatory cytokines that reduce damage from pollution, sun exposure, and other sources.

Sleep is also the body's time to release optimizing growth hormone, known as the “Fountain of Youth” hormone. This hormone keeps skin from thinning so that a person actually does look younger. [3]

#3: Exposure To Red Light Can Reduce Wrinkles

Fact. Yes, this one does sound a bit like science fiction. There's a reason for that – NASA has actually used light therapy to help astronauts' wounds heal faster. [4]

Here's the science. Red and infrared wavelengths used in QuasarMD anti-aging devices penetrate up to an inch into the surface tissue. There, they stimulate the cells responsible for producing fibers that protect skin's elasticity and smoothness. This helps to keep skin looking younger. [5]

#4: Sunscreen and Moisturizer Can Keep Skin Looking Younger

Fact. Moisturizer keeps the skin hydrated, which directly helps to prevent the development of wrinkles. A 2010 study published in the British Journal of Dermatology showed that a 28-year-old woman with dry skin will have 52 percent more wrinkles by the age of 36. If the same woman hydrates her skin well, however, she will probably only see a 22 percent increase in wrinkling.

According to lead study author Dr. Greg Illebrand, a principal scientist for Olay: “We can dramatically delay the onset of persistent wrinkles by protecting skin daily with an effective moisturizer and sunscreen.” [6]


“Daily” is an important word if you're looking to develop fewer wrinkles and this applies to both moisturizer and sunblock. So many of us spend our days indoors, thinking that means we don't need sun protection, but natural light finds a way to reach you. You probably spend at least part of your day near a glass window, whether that window is in your car, your home, or your office, and that means you still need protection. Glass doesn't block UVA rays, which are responsible for wrinkles and other signs of aging. [7]


The oxidative process is a key driver of skin damage from UVA rays. Fortunately, according to research published in the journal Current Problems in Dermatology, topically applied antioxidants can significantly increase the skin's ability to protect itself from this damage. Study authors believe that antioxidants are particularly effective in sunblock because they increase the anti-aging capability of the product. [8]

#5: Greasy Food Causes Acne

Myth. Although 51 percent of people in the US believe that eating too much fried food leads to acne, research has not supported the connection. The American Academy of Dermatology, the US Food and Drug Administration (FDA), and the Mayo Clinic have all issued statements saying that there is not enough evidence to suggest that you will get acne if you indulge in burgers and fries. [9]


Greasy food doesn't cause acne, but there are some foods that actively help your body to fight breakouts. Omega-3 fatty acids, found in fish and fish oils as well as nuts, seeds, and plant oils, can reduce the inflammation that is the root process behind breakouts. [10] Ginger and turmeric, available as seasonings and as components of healing teas, can have the same effect.


The liver handles all detoxification in the body. This includes getting rid of unnecessary hormones, which can contribute to breakouts. If you want to help it do its job well, eat a lot of dark green leafy vegetables and brassica varieties, such as broccoli and cabbage. High fiber foods, such as whole grains, beans, and fresh produce, can also help the liver work at its best. [11]

#6: Cleaner Skin Is Clearer Skin

Myth. Many people wash their faces frequently thinking that doing so will keep breakouts at bay, when in fact the opposite is true. Skin that is prone to acne is also particularly sensitive. Scrubbing it repetitively, particularly with harsh products, is only going to irritate it and dry it out. This can actually make acne look worse. Twice a day with a gentle cleanser is much more effective. [12]

#7: Blue Light Can Treat Acne

Fact. This is another one that sounds too futuristic to be true. Washing your face doesn't help, but going under a blue light can?

Actually, yes. Blue light used in QuasarMD acne devices kills the bacteria that causes acne, which means that it can either treat an existing outbreak or reduce bacteria levels before pimples develop. In surveys of patients who tried blue light therapies, up to 90 percent of participants saw an improvement in acne symptoms.  [13]

The Take-Away

Some of the information out there is true; some isn't. Don't be afraid to do your own research and find out what the experts have to say. Sooner or later, your skin will thank you for it.

What Exactly is Light Therapy?

Light therapy, commonly referred to as phototherapy or heliotherapy, uses the inherent power of light to improve the health of your skin without the use of the hazardous chemicals that are present in many over-the-counter and prescription skincare products. The best part is that with personal light therapy products from QuasarMD, anyone can experience the amazing benefits of light therapy from their own home.

Light therapy (including blue light therapy and red light therapy) is often associated with skin conditions such as dermatitis, psoriasis, eczema, or acne. However, the benefits of light therapy extend beyond dermatological conditions and the practice is now commonly used for improving overall skin health and complexion. Light therapy can be used for anti-aging, to help eliminate wrinkles, heal skin, and reduce pain. The most beneficial light therapy products, such as QuasarMD products, reject harmful UV rays and instead employ LED lights.

Why use LED lights instead of UVs? The switch from using UV rays (which can have adverse side effects) to LEDs, or Light-Emitting Diodes, was advanced when NASA discovered that LED lights could speed the healing of certain wounds in space, vastly improving medical care for their astronauts. Removing the UV lights from light therapy products has allowed light therapy to be virtually free of side effects.

Two Types of Light Therapy and How They Work

There are two types of light therapy used for skin health - red and blue light therapy. Each method of light therapy has its own unique benefits and selecting which light therapy to use will depend on your skincare needs - with two common needs being anti-aging or anti-acne.  QuasarMD has a wide catalog of red light therapy products to suit your needs. Our products come in various colors and sizes so you are sure to find something to fit your budget.

Red Light Therapy

Red light therapy utilizes four separate wavelengths of light - amber, red, super red, and infrared. These four wavelengths each have their own benefits, and when they are distributed from a light therapy device to different areas of the skin, they are able to penetrate deeper than visible light. Red light therapy uses these specific wavelengths of red lights to enhance the functioning of the mitochondria, thereby improving cellular respiration and in turn, cell function. Improved cell function and reduced inflammation result in clearer, healthier skin. Red light therapy is generally selected over blue light therapy when the goal is to improve the health, look, and feel of skin, and harmful bacteria is not present. The benefits of using red light therapy are plentiful!

Blue Light Therapy

Blue light therapy is widely considered a non-invasive treatment for acne and other skin conditions such as sun damage and skin cancer. Blue light therapy works by using light that falls in the blue wavelength range to target and kill certain bacterias that live on the skin and beneath the skin's surface within follicles and pores. One common bacteria targeted by blue light is Propionibacterium acnes, a bacteria that is commonly found on acne-prone skin. If the bacteria can be eliminated, then the skin can heal and blemishes will be reduced. Many people use a combination of blue light and red light therapy.


  • Treats inflammatory acne and bacterial skin conditions
  • Kills bacteria that causes acne without drying out the skin like traditional acne products
  • When traditional acne medications have not had the desired effect, many people respond to blue light therapy
  • Penetrates deep into the pores where bacteria can breed
  • The entire process is easy to fit into your busy life and takes just a few minutes a day!
  • Improves the texture of the skin and smooths out imperfections
  • Drug and chemical free so that you never have to worry about the safety of what you are putting on your skin
  • Recommended by dermatologists to treat acne
  • Using LED blue light therapy is clinically proven and non-invasive

Light therapy is a safe, natural way to combat a wide variety of skin concerns and improve overall skin health for an unparalleled radiance.
