    I’m 24 years old with sensitive skin. Will P50W lotion be harsh for me? As it’s an overnight treatment. And will my skin get thin in the future? It would be great if you could help me out, I’m really confused

    • Jenny says:

      The P50W is the most gentle of the Biologique exfoliation lotions and was made for sensitive skin, but with that said, any type of actives can be irritating depending on your current skin conditions. If you do want to try this I would take it really slow – start using maybe once a week and build up your tolerance from there. Also start with the travel sized bottle. Since these are sold by esthetic spas, you can email them for more information if you’re uncertain.

      As for thinning the skin, all exfoliating products will “thin” the top layer of your skin because it speeds up the removal of that dead layer of cells. However your overall skin structure doesn’t change. As long as you’re not overexfoliating and compromising your skin’s moisture barrier you should be ok!

    Great post! On the days you do not use the P50W are you using a Retin A?
    I also use both and did find my skin was looking parched when I used them on alternate days. Thinking I should scale back on one of them during the week. What do you think? three days with the Retin A and two days with the P50W in a week, or something like that! I do like the results yet now I’m not sure if it is the P50W or the Tretinoin Retin A that is making my skin look better. I do think the P50W does make my skin look smoother; more glass-like. Love to hear your thoughts on frequency using both products. Thanks again for sharing!

    • Jenny says:

      Thank you! I do not use both on the same day as that would be too strong for my skin and I don’t want to risk overexfoliation. I think it’s always best to start slow, and you can always increase the frequency after a few weeks when your skin has had time to adjust.

      So for me I’ve actually scaled down to Retin A on 2 nights, P50W on 1 night, and Vitamin C on 1 night since my skin is drier in the winter. For me I feel like P50W delivers more immediate results, but Retin A works both on the surface and deeper levels to stimulate collagen production, so you won’t see the results until after a month or even 2. Hope this helps!

    Thank you for your thoughtful review of this product. I was a bit concerned since I’m currently using Curology as well. When you were saying that do not use this when using Curlogy, does it mean that I cannot use Curlogy with this product at the same time or I can use P50W on one day and Curology on the other day? Thank you!

    • Jenny says:

      Hi, I personally would not use them in the same routine in case of overexfoliation. I prefer to err on the side of caution, so I’ll use curology one day and P50W on the other days.

    This brand is new to me, but this lotion sounds interesting. I love using AHAs in my skincare and regular use just transforms the skin. I like the detail review Jenny. :-) I am learning so much

    • Jenny says:

      Thanks for reading Via! I used to be wary of AHA’s, but now that I’ve found a gentle one for my skin type it”s become an essential in my routine!

  5. I finally found a SA close to me who is selling this toner but it’s expensive! Ugh! I am so hesitant to spend so much money on it because my skin doesn’t need the extra help and normal exfoliating toner has done wonders for my skin. Maybe when I am 45 and transformed into an old wrinkly hag, I will then take the plunge. LOL!

    • Jenny says:

      Lol I think you might need to wait another 20+ years then because you are nowhere near looking like a hag! I didn’t buy the full-sized products either because of the price, but their smaller size lasts a surprisingly long time! I’ve had mine for a few months now and still have a lot of product left!

    9.5/10 performance is pretty good, not to mention the good ingredients it comes with. I’d love to try this. Thanks for sharing dear!

    I need to try this

  8. LOVE how thorough your review is – would love to try this stuff out!

    Thanks for sharing me Jenny! Looks like a simple and chic brand.
    The vinegar scent sounds interesting however great all the same to hear that you enjoyed the brand.

    I’m not entirely confident about chemical exfoliation because I’m new to it and I don’t want to mess up my relationship with my skin now. But it’s great to know about products such as this because they might come in handy. Thank you for sharing your review about this.

    I have always been curious about this product.. thanks fro explaining and reviewing in details… my skin doesn’t tolerate too many chemicals and acids so I try to keep my skincare routine simple … This toner sounds great to start with… ❤️

  13. Radi says:

    I haven’t tried their lotions or really anything by this brand. I like your review!

  14. Gabrielle says:

    I hear sensitive skin and I’m IN! I vaguely remember this brand name and so it’s lovely to know more about it :) x

  15. I always find your reviews so helpful Jenny! I have always got on great with Pixi’s Glow tonic but as I have sensitive skin I’m wondering if this would be a better fit. I can look past the vinegar smell if it does the trick haha xx

  16. Naya says:

    This was a great read. How come I have never heard about this gem before? I do not mind an odd scent as long as results are there and it seems like this was a wonderful discovery. I mean, don’t we all want to go foundation-free? Count me in! xx


  17. I’ve wanted to try this toner forever! Yes the whole buying through spas though definitely deterred me though I feel like I might have found one site that sold it directly. I should definitely try to find an esthetician here.

  18. Everything is beautiful! I have to try the products of this brand!

  19. Claire says:

    i love the ingredients of this lotion ! i’d like to try it for sure!

  20. I love that you listed what is inside, because I find myself looking at those on the bottles of anything I look at for my beauty routine. :) This is such a great review.

  21. I admit I am a bit confused by the different BR P50 versions, but I really want to try them in the future at some point. Just from reading here I don’t think that pixi Glow Tonic is a dupe for this one. I mean, both are gentle acid toners, but that is where the similarities end.

    Okay I need this!

  23. This has been on try list for ages but I still haven’t pulled the trigger yet. Your review was very enlightening. Thanks Jenny! Good to know that it worked so well for you and it didn’t sting and or smell horrendously bad. There are so many versions of it that I think when I’m ready to go for it, I’ll just have to go to Rescue Spa in person and get a recommendation on which one would be right for my skin.

    • Sakina says:

      Hi! Thank you for your information. I have some questions as you’ve used this product.
      I’ve started to use Lotion P50, it’s almost 14 days. Also I use placenta serum and iso-placenta cream.
      But I have breakouts. Also I have closed comedons and blackheads.
      Will they disappear with this Lotion? Or I need facial cleansing instead of this lotion?
      Also how much time we need to see the result?

      • Jenny says:

        I’ve only used P50W, P50 is the original and much stronger. However they all work to exfoliate the skin and increase cell turnover rate, so yes theoretically they should help with your issues, just make sure you slowly introduce P50 into your routine so you don’t irritate your skin during the process. Results and time vary, there’s no way for me to give you that answer, but most skincare products take at least 4-6 weeks to show results.

        “Or I need facial cleansing instead of this lotion?” Not sure what you mean by this, but cleansing should be a part of every skincare routine and products should be applied to cleansed skin only!

  24. Jennifer says:

    This sounds like a great product!!

  25. Elena Isabelle says:

    I really love lactic acid as a chemical peel and have been using it for a while now. the lotion sounds actually so good.

    • Jenny says:

      I really like it, but if you use lactic acid already in peels, you might find Lotion P50W weak in comparison. It might work great as a daily toner for you though!

  26. Maria says:

    Such a helpful post! Very good review and in depth. I’ve never heard of this brand but it sounds wonderful! Thanks for sharing.

  28. Love that this toner is gentle! This is a wonderful review and I need to check this out soon.

  29. Gabrielle says:

    As i’m new to trying chemical exfoliants of any kind, this sounds like an ideal option! It’s nice to have my eyes opened to cult classics in the skincare world as well, as it’s a universe I’m becoming more and more interested in :) Hope you’re having a lovely week so far! x

    • Jenny says:

      Yay I hope you’ll get a chance to try this, it’s really lovely and has been around since the 70’s! Hope you’re having a great week too!
