Book the telehealth appointment tonight and ask for tretinoin by name. ## Why it works Tretinoin is vitamin A already in its acid form. Unlike retinol, it needs no conversion by skin enzymes. It binds the retinoic acid receptors in the cell nucleus directly and changes which genes skin cells switch on. That directness is why it is prescription-strength, why it works faster than cosmetic retinoids, and why the irritation phase can't be avoided. ## Where it fits Tretinoin is a move in 8 protocols. Each one opens the plan it sits in. - [Fade Your Stretch Marks](https://elonmuscular.com/protocol-stretch-marks/) - [Clear Your Acne](https://elonmuscular.com/protocol-adult-acne/) - [Fade Your Acne Scars](https://elonmuscular.com/protocol-acne-scars/) - [Smooth Your Bumpy Arms](https://elonmuscular.com/protocol-smooth-arms/) - [Stop Your Razor Bumps](https://elonmuscular.com/protocol-smooth-shave/) - [Get Rid of Your Dark Circles](https://elonmuscular.com/protocol-dark-circles/) - [Slow Skin Aging](https://elonmuscular.com/protocol-aging-skin/) - [Look Better](https://elonmuscular.com/protocol-skin-and-hair/) New Heroes The full library.
