Hi,
So I've decided I'm going to give this a go, but there's so much information out there, some of which is rather conflicting, so thought I'd come on here and ask you lot 
I have seen a video on YouTube saying you should only get an air tight opaque bottle as the effects will wear off. I guess this makes sense. Is this true?..
Can you recommend me a starting point serum or cream please?
I don't have sensitive skin generally. Possibly combination, but not really sure tbh. I already look after my skin, but at 34, aging seems to have accelerated 
Advice please!
TIA
