Also I think that you have to lessen your intake of l-arginine containing foods. l-Lysine has something to do with creating a large ratio of lysine to argine to stop viral replication in herpes simplex anyway. So if this is related to herpes in some way and l-lysine is helping it might be good to lessen your intake of l-arginine foods while your at it. Wikipedia says Arginine plays an important role in cell division so the building up of skin on our lips occurs through cell division so lessening intake of this amino acid might help. Wikipedia also says "but dietary arginine may affect the effectiveness of lysine supplementation."
l-argine is found in many things including nuts (coconut, pecans, cashews, walnuts, almonds, Brazil nuts, hazel nuts, peanuts), seeds (pumpkin, sesame, sunflower). So if ur lip balm has these oils in it then maybe this could make the problem worse? However I also found this quote, "In addition, test tube studies suggest that L-lysine in combination with L-arginine (another amino acid) increases the activity of bone-building cells and enhances production of collagen." and this one, "Adults with herpes simplex should follow these guidelines: To treat symptoms: 3,000 Ė 9,000 mg per day in divided doses". Lysine supplements are considered safe and nontoxic. However, one animal study found that chicks fed with L-lysine developed elevated cholesterol and triglyceride levels. For this reason, individuals with cardiovascular disease and those with elevated cholesterol and/or triglyceride levels should consult a healthcare practitioner before taking lysine supplements.
