Can anyone recommend a retinol serum?

[overweightcat]

Preferably that doesn't break the bank so I can repurchase when it runs out.

I've been looking at the Ordinary one as it seems really affordable compared to some of the £50+ I've seen but I'd really love to get recommendations and advice from people that use retinol.

Is the ordinary one worth it or is there something else ideally under £30 that's even better?

TIA

I've bought the inkey list one today

Beauty Pie one is fab

I would really recommend Dermatica. It’s prescription so will be more effective than what you can get over the counter. The retinol works out as £20 ish for a month supply - but mine lasts about two months as I use every other night. They currently have an offer on with the first months supply free.

Another shout for Inkey List here. Good for sensitive skin, as is Pixi Collagen & Retinol Serum - both good for beginners with sensitive skin
