I have quite an embarrasing amount collection of everything skin care, and I have a Caroline Hirons approach of mixing it around depending on skin, weather, time of the month, etc.
At the moment for example, I have had a breakout due to hormones and some redness due to the cold/central heating, so I've been using a salicylic acid toner, then a serum for problem skin in the morning, and one that I find helps with the redness in the evening. It's sorted it out. I know these aren't the same things you need, just an example of my approach, I guess?
For anti-ageing both vitamin C and retinol are okay as long as not too strong, you're not sensitive, maybe don't use both every day. The only retinol product (or a relative to retinol) is Sunday Riley Luna, which I find is also good for brightness, glow and helping clear away old acne scares. It is really expensive though. If I use a vitamin C serum I'll use it in the morning as they tend to be a bit lighter IME and more of an immediate brightening affect, which is obviously a nice thing to have when you're being seen, rather than at night. Typically, I'd use both a couple of times a week (Luna at night).
I can't seem to find an ingredients list for the Aldi one, but algae tends to be hydrating, which will help plump out fine lines, rather than get rid of them. Really only retinol/vitamin a can do that, but vitamin c/glycolic acid will improve dark spots and skin texture, and other things that can look ageing.
Sorry to waffle. I hope I don't come across like a know-it-all-smart-arse. I just really love skin care. I know very little about anything else
