We don't have video equipment so we won't jump on the YouTube self-promotion bandwagon. I put my knowledge on my website and I try to be honest. First of all, if a seller claims that your stretchmarks will disappear, it is a lie. Currently there is no method that can make stretchmarks disappear. Stretch marks are very deep scars. Only in very rare cases, stretch marks are so shallow that it is possible to remove them completely. You can greatly improve their appearance though.
White Lotus is not a credible company. We exposed their use of fake before-and-after photo's here:
https://http://www.owndoc.com/dermarolling/white-lotus-breast-enhancement-scam/Their bad advice not to use any vitamins as supporting treatment but their green tea is understandable - it is impossible for any European company to import Retinoic acid creams, for example. So they simply are not able to sell them, and we are because we use a third party. They don't want to lose customers to us, so they claim that vitamins are "bad for the skin". They also tell you to roll three times a week with a 1.5 mm roller, so that you'll maybe even ruin your skin and the roller will be blunt in at most two months and you'll need to buy a new one. And their prices are very high as well.
White Lotus' business model is based on serving the "magical thinkers" niche. The "flower-power hippies". They have zero scientific backup for their "acupuncture breast augmentation" and other wild claims and instead of using vitamins that occur naturally in the body, they want you to believe that vitamins are bad but "ancient oriental wisdom" (powdered tiger bones, anyone?) and herbal teas are good. Quackery. Stay far away from sites that fake their pictures.
There are medical studies showing that A-Ret helped fresh stretch marks and to a much lesser extent old stretch marks. I recommend applying A-Ret to the stretch marks immediately after dermarolling in case of stubborn stretch marks. It will sting and make them red for days.
I certainly do not think that A-Ret causes more stretch marks. They keep popping in your case because the tissue volume is increasing, probably in combination with hormonal causes. Nobody knows why some bodybuilders get stretch marks and some do not, why most pregnant women get them but some do not. I am working on an article about the cause of stretch marks and related issues.
You should not stop exercising but instead limit it a bit. Exercise less or less intensely, so that the muscle volume doesn't grow so quickly. After all, nicely toned muscles even with stretch marks look much better than weak, flabby muscles without stretch marks, in my opinion. Especially on a man.
The slower the muscles grow the lesser chance of developing stretch marks. I know you probably did not overdo the workouts, you were just unlucky.
BTW if you used steroids to boost your muscle growth (I do not think you did but I want to mention it for others) stop taking it, many anabolic steroids can cause stretch marks!
Stretch marks originate in the dermis and it may take a while to show on the skin surface. Your dermis got "rips" and they are now slowly popping up on the surface.
Dermarolling the entire area to prevent new rips is worth trying however so far we have no studies proving that dermarolling or anything else can prevent stretch marks. You have to try.
Fresh stretch marks are red because there is still blood in them. They will eventually fade.
You could combine your 1 mm roller with a 1.5 mm ONE LINER that is for the intensive treatment of stretch marks:

Yes, young people have quicker healing.
You can do self-tanning while dermarolling, no problem, nevertheless, dermarolling speeds up the turnover of skin and that will make your tan fade faster.
