Skin and me or embassy of beauty P50?

[MrsKDB]

Which will make the most positive difference to my skin?

Early 40s, fine lines around eyes and a bit on forehead. Not terrible for my age but would like to look a bit tighter / fresher. Have used retinol / glycolic regularly for 4-5 years but would like something stronger, particularly to fight the lines but also to bring a bit more glow to my skin.

Which has the best effect? I know I can’t use both at the same time so need to choose!

You can use both if you tolerate tretinoin well and aren't overly sensitive, just be mindful not to overuse it. I'd advice getting tretinoin between the two anyhow as it's the thing that will progressively improve your skin and (very slowly) reverse signs of ageing whereas an acid toner only does so temporarily. Get to a good maintenance dose on Tret and if you tolerate it well you can add in P50 (starting with the W version) at that point if you feel the need for it.

*And never use both in the same routine.

Brilliant, thanks so much for the advice! I will get started with skin and me.
