How can I make my lips lighter in colour?

If I were in your shoes, I’d definitely NOT stop taking isotretinoin until I’ve finished the course. Many studies have shown that the risk of acne relapse is much higher if you don’t complete the course. The total dosage you need to take depends on your BODY WEIGHT as well. Tapering your dosage wise, please speak to your doctor. Again, if I were you, I’d just stick to the dosage that he has placed you on, since it appears that you are not suffering any adverse effects (apart from dry lips, which is very common).

There are many different brands of fillers , but the main difference is that one group ( Hyaluronic Acid ) provides an immediate filling effect but does not stimulate significant amounts of collagen , whereas the other group known as Collagen Stimulators ( Radiesse, Sculptra, Ellanse) stimulates your skin to produce large amounts of collagen. For your lips, it’s best to use Hyaluronic Acid as it’s not suitable to use collagen-stimulators here. 1cc of Hyaluronic Acid can cost between $500-1200 depending on the brand and the doctor’s reputation.
