I strongly recommend waiting until the redness has subsided. Is this blood pooled under your skin or just erythmia? Sorry, my PC refuses to load your gallery. If it's the latter then you could start to look at using a retinoid/retinol, like Retin-A. If your depressed scars are still red/purple then there actually is a chance that they may fill in... however if they're significant enough then I doubt they'd improve to the point where you have perfect skin, sadly.
Silicone fillers are nasty. I know in the right hands and via the microdroplet approach they can look amazing and can be safe but anything injected in the skin that is truly permanent should be a worry. What will you look like when your skin starts to sag? I guess you could argue that you're too old to care by then but... just my opinion.
If I were you I would get myself into an excellent skin care regime right now. I would also give my skin a while to recoup from the acne and from the medication. I would use this "waiting" time to research my options for scar correction if the scarring ends up bothering me. Sometimes playing the game of patience is really the best thing.
Also, if you like the idea of fillers then take a look at Airgent (I think it may now be called Enerjet also). No needles! The filler side of the Airgent is actually the secondary objective. The first is to create controlled trauma to the deeper layers of the skin to break up scar tissue and improve it long term. The extra boost is that you also get the immediate effect of the Hyaluronic Acid based filler. I'm looking into this treatment at the moment.
