You look great but as a physician, i wanted to inform you about some possible long term effects of tretinoin as the studies due to the limited length of studies of tretinoin in regards to an entire human lifespan.
Retinol is considered an exfoliator, and this repeated shedding of the upper dermal layer forces the skin to produce new cells. Although new cells are constantly created below the skin and enhanced by the communication and cell turnover facilitated by the Retinoic Acid, there is some concern that at the Hayflick Limit (the number of times skin can regenerate itself before reaching its limit, at 52 times), the aging process will actually be enhanced because cells are not able to multiply indefinitely.
With just an A-level in Physics to qualify him, Adam was able to construct a home-made device consisting of a box containing a GPS, radio and microprocessor. After 40 hours of working on his gadget (and detailing it all on his blog) , Adam attached it to a balloon and it soared to an incredible height of 110,210 ft (33,592m). The device took two and a half hours to get 20 miles up into the atmosphere, before it took impressive views of Earth from space. Adam used a GPS tracker to track the device’s ascension and also an attached radio transmitter to find it when it fell back to earth.
