So this was an absolute game-changer for me, but it was also something I didn't even consider as a potential option until about 4 years into my BDD.
When I look back, I find it really surprising I didn't at all consider it, but by the chance I'm not an outlier, I'd like to make men aware that this is a something they can consider.
On the website dermnetnz.org on the Cosmetic camouflage page, it says this:
'Cosmetic camouflage has been shown to improve the quality of life significantly. It improves patient self-esteem and creates a sense of personal well-being.'
This is when I first had the notion that this was something I could try, and I haven't looked back since.
At least for me, getting my skin to look initially better was really not much effort and surprisingly not one person noticed I had anything on my face.
However I am still getting better and better at using it. I recommend allowing yourself some time to learn how to do it before giving up on it, as does DermNet: 'It may take some practice to achieve a satisfactory final appearance.'
Also I highly recommend dermnetnz.org. It's a reputable, non-profit dermatology resource with guides for people with any kind of skin-related questions, and it was recommended to me by my Doctor.
And if you'd like confirmation that this can be effective treatment for BDD, see this video, a video brought to my attention by @[email protected] (thank you Sora!) which is made by the BDD Foundation (you can see the community sidebar for details on this organisation but in short it's a very helpful BDD support charity). And here is a screenshot of the part of the video with the confirmation: 
Thanks for reading, and I hope this might be of use to someone :)
Woo! That's really nice to hear! You're really lucky haha I remember for me during my first week while my body was getting used to it I was feeling really nauseous and couldn't sleep lol.
Also like @[email protected] said I agree you should be careful as it is unusual to be feeling better that quickly. There are many reasons that could happen tho, the obvious one is placebo (but who cares really if you're feeling better); second one is that the desicion to go get antidepressants has had a positive benefit to your life and made you feel like you want to make even more progress, in turn increaseing your happiness; third one is mania (extreme euphoria) which is extremely unlikely, but a dangerous potential side effect of anti-depressants and you probably need to call an ambulance if this happens; and finally fourth one is that it really has just worked extra quickly for you, which is unlikely but not impossible!
So whatever the reason is I'm glad it's working out for you, just be mindful of your emotions but don't worry too much as you'll probably be able to tell if something is seriously wrong.
Good look for the future :)
