Needle injections are great in more superficial areas of the lips, such as philtral columns, vermillion border, and the finer lines around the lips. When more "inflation" of an area is needed micro-cannulas have proven to be a better choice.
The advantages of micro-cannulas include less bruising, less swelling, less pain. Micro-cannulas also allow for smoother contouring in areas such as jawline, cheeks, chin, tear troughs, brows, and even the body of the lips- any area that require deeper injections for sculpting, contouring and "lifting."
WebMD explains that it is appropriate to treat most insulin overdoses at home. The patient must first check her blood sugar. It is recommended that the patient drink four ounces of regular soda or juice and eat a piece of hard candy or a glucose tablet. If the patient has not eaten a meal, this should be done immediately. Consuming 15 to 20 grams of carbohydrates usually raises the blood sugar level. The patient is advised to rest and recheck the blood sugar level after 15 to 20 minutes. If it is still low, recommendations include consuming another 15 to 20 grams of fast-acting sugar.
