I have tried other brands, but they irritated my skin, so I ditched them. I haven't done a side by side comparison of the ingredients of the different brands, so I can't speak to that. Ultimately, I'm not sure how useful a comparison&nbsp; would be, unless there are some ingredients you know you should steer clear of. The real test is on your skin. </p> https://youlookfab.com/welookfab/topic/pc-1-retinol-vs-bps-4-retinol-booster#post-2324814 Wed, 31 May 2023 22:54:26 +0000 Angie 2324814@https://youlookfab.com/welookfab/ <p><b>em</b>, I have bad reactions to rentinol so don't use it at all. Maybe someone else will chime in? </p> https://youlookfab.com/welookfab/topic/pc-1-retinol-vs-bps-4-retinol-booster#post-2324294 Thu, 25 May 2023 15:53:25 +0000 em 2324294@https://youlookfab.com/welookfab/ <p>I have used a mixture of prescription tretinoin and Paula's Choice's 1% retinol booster for ... 25? years. I dropped the prescription stuff about 10 years ago just because I forgot to renew it one day and then never bothered. I have never noticed a difference in my skin. Anyway, I am now thinking of switching to Beauty Pie's 4% retinol booster, but am having trouble comparing/contrasting the ingredients list. Is there anyone out there who can dissect them and report back on the pros/cons of switching? Thanks.&nbsp; </p>
