I've heard that nodules can form as a side effect of collagen boosters. What causes this? Can it be prevented or resolved?
Nodules (lumps under the skin) are more likely to occur if the ingredients do not spread evenly in one area or if there was insufficient massage after treatment. Areas like the eyes and mouth, where the skin is thin and there is a lot of movement, are relatively more likely to feel nodules, so adjusting the dosage and injection method is important. To prevent this, consistent massage is key, and while mild lumps often resolve over time, if hard nodules persist, it is recommended to visit for evaluation.
