Ultra Gentle Smoothing Serum uses a soothing 10% lactic and glycolic acid blend to lift away dryness and discoloration for red, sensitive skin types.

Regular price


"For sensitive sets who want the glow-inducing benefits of an acid but are too afraid to try one, consider this gentle formula your workaround."


  • Ultra Gentle Smoothing Serum by Renée Rouleau uses a 10% non-drying glycolic acid and lactic acid blend to dissolve away dry cells and lift discoloration to reveal smoother skin with fewer visible pores, lines, and wrinkles. Soothing, fragrance-free ingredients work to improve the moisture barrier function, keeping sensitive skin feeling calm and comfortable.

    This is a safer and more effective way to exfoliate for those that get easily-irritated from abrasive facial scrubs. Skin types with redness or rosacea will respond favorably to this gentle, yet high-performing formula, and with continued use will find their skin acting less sensitive yet revealing a brilliant clarity. The result? Beautiful, healthier and smoother-looking skin by Renée Rouleau. 

    Sizes: 0.5 fl oz or 1 fl oz

      Love it!

      My skin is too sensitive to handle most products. This product helps with aging and doesn’t irritate my skin!

      This is the only RR product I've bought that I really haven't like. It's scent is clean, fresh diapers. It doesn't last long and is quickly overcome by RR lotion, but it's not the way I want to start my morning. It's both too drying and not exfoliating enough for my skin, though I was testing something outside of my recommended skin type.

      I much prefer the Skin Correcting serum with targeted use of the BHA Clarifying serum.

      Hey Sam! Thanks so much for taking the time to leave a review!
      Like all of our acid serums, we recommend using the Ultra Gentle Smoothing Serum at night after cleansing and toning since sun sensitivity can increase with usage due to the AHA's. (This also means you'll want to be diligent with your sunscreen application!) As the name implies, this is our gentlest acid serum, formulated for sensitive skin types without acne concerns. If you want an alternative to the BHA Clarifying Serum, check out the Pore + Wrinkle Perfecting Serum! Renée also suggests exfoliating no more than five times a week. So ideally, you would use an exfoliating acid serum like Ultra Gentle or BHA Clarifying Serum three nights a week, then once a week, you would use an exfoliating Peel and Scrub, like the Triple Berry Besties! This blog post by Renée includes a helpful exfoliation schedule >
      Skin Correcting Serum is a hydrating acne-preventative serum that can be used in the morning and on nights you aren't exfoliating! This blog explains serum cycling more in-depth and includes a helpful list of ingredients that should never be combined >

      INCREDIBLE for #5 Sensitive & Red Skin!!!

      I have incredibly sensitive, rosacea-proned aging skin. I was expecting my skin to turn red and break out at least at first with this product. All I had was a tiny bit of stinging the first two times. I’m telling you, between this and the Advanced Resurfacing Serum I am a new woman !!!! Thank you Renee!

      Smoothing and gentle - just as described!

      I vary my serums throughout the week, but this is one I use 3 nights a week. I love that it's gentle on my sensitive skin, but I still get the benefits of an acid. No more dry patches and my skin is smoother. As a bonus, I also pat a little under my eyes and then top with Total Eye Repair Creme. Love it!
