Although most of us are able to breathe through our mouths, you should always favor breathing in through your nose. Your nose is specifically designed for the intake of air and will help filter out particles and dust. Your nose has thin hairs and mucous that will help keep the air entering your lungs clean. Breathing in through your mouth may cause your mouth and throat to dry out. Your nose produces a gas called nitric oxide that enhances your immune system and may even increase the oxygenation of your blood. Either due to bad breathing habits or from being under stress, many people take quick and shallow breaths. Breathing provides vital oxygen to the body, and these short breaths don't carry as much oxygen as deeper and slower breathing will. Inhale through your nose. Imagine you are filling your belly up with air. At the start of the breath, your stomach should rise first, before your chest. When your stomach is "full" continue the inhalation, allowing the chest to rise now. Take your time breathing in. A good breath should last around five seconds on the inhalation. Just as with inhaling, exhalations of the breath should be done slowly. Exhaling too quickly lessens the time that our lungs can intake oxygen and remove carbon dioxide. Exhale through your mouth. You can try pursing your lips to slow the exhalation. Let the lungs push the air out at their own pace. Try not to force air out of your lungs. Start the exhalation at the stomach level, letting your diaphragm relax first. Your chest should fall with or after your stomach does. Don't rush the exhalation. Just like with the inhalation, you should take a few seconds to exhale.

Summary: Breathe through your nose. Take deep breaths. Exhale properly.

Prior to microneedling at home, you need to choose a device that is best suited for you. There are three different types of at home microneedling products: a derma roller, derma stamp, and derma pen. Derma rollers are the least expensive option and roll along your skin like a paint roller. Some dermatologists recommend derma stamps and derma pens because the vertical penetration is less painful and allows for easier maneuvering around the mouth, eyes, and nose. Shop for a microneedling device online. These devices range in price from about $50 for a derma roller to upwards of $200 for a derma pen. Most at home microneedling is performed using much shorter needles than those used by aestheticians. For instance, at a clinic needles can range in length from 0.5mm to 3mm depending on the type of treatment. When performing the treatment at home, you should use shorter needles. Needle lengths that range from 0.25mm to 1mm are recommended for general anti-aging procedures. If treating acne scars, you may want to use a longer needle around 1.5mm in length. If you are opting for a longer needle, talk with your dermatologist prior to treatment. Before using a microneedling device, carefully read all of the instructions. The instructions will provide you with detailed information concerning set up, storage, and how to safely use the product. Each product is slightly different, so it is very important that you read the instructions that accompany the device you purchase. Depending on the type of microneedling device you selected, you may have to insert the needle cartridge into the device as well as other minimal assembly that may be required. Before you begin the treatment, sanitize the microneedling device. Place the device, needle side down, in a small bowl of rubbing alcohol. Leave the device immersed in the rubbing alcohol for at least 1 to 2 minutes. Finally, before you begin the treatment, wash your face and remove all makeup. Wash your face using a gentle cleanser. This will help remove all dirt, grime, and makeup from the surface of your skin. You do not want any bacteria to get into the skin as a result of the microneedling process. As a result, you should always begin with a clean face. Pat your face dry after washing.
Summary: Select a microneedling device. Determine the length of the needles. Read all of the instructions. Sanitize your microneedling device before use. Wash your face and remove makeup before use.
