Recommended frequency of Livicol for a dull complexion caused by lack of sleep

I have been suffering from sleep deprivation lately due to project deadlines, and my complexion has turned ashen. Even when I apply a generous amount of expensive cosmetics, they just sit on the surface, making me realize that my skin barrier has broken down.
I simply cannot get rid of this dryness and firmness with just a simple surface moisturizing cream, so I am seriously looking into the Revicol treatment, which is said to replenish collagen from the dermis layer deep within the skin.
Since it claims to restore elasticity by powerfully boosting the skin's natural regenerative power rather than just providing temporary hydration, it seems like the most necessary treatment for my current, terrible skin condition.
However, since it is said that it is difficult to feel dramatic changes with just one skin booster injection, I am very curious about the total number of Revicol sessions usually recommended.
Approximately what is the official recommended frequency of Revicol treatments guided by the hospital to completely eliminate severe internal dryness and for a subtle, clear glow to begin on the face?
My skin is very thin and sensitive, so I am worried that receiving injections too frequently might actually cause friction and irritation. What is the safest interval for visiting?
If the cost and time invested can result in flawless skin where makeup adheres perfectly like a peeled egg, I am firmly determined to schedule the Revicol treatment exactly as the director instructs.
