Comparison: Caudalie Glycolic Peel & Ren Glycol Lactic Radiance Renewal Mask


I’ve been asked a few times to do a comparison on these two fellas. I enjoy both the products and couldn’t choose one over the other. Here’s why: Both claim to do similar things such as boost radiance in complexion, renew skintone & texture, and help with hyper pigmentation. They’re both free from parabens and sulfates. I particularly enjoy Caudalie’s scent (typical scent of Caudalie products) and creamy texture. Whilst Ren has more citrusy kick in a jelly like texture. Both are easy to apply and wash off. They’re equally pleasant experiences on my face.
From an Ingredients perspective, Caudalie is enriched with Glycolic (6th ingredient), Grape Seed Oil (typical to caudalie formulation, 9th), Pathenol (11th), and Squalene (12th) among others. As the Glycol Lactic name suggests, Ren masque has higher concentration of Lactic acid (5th & 8th ingredient) in a cocktail of Glycolic (10th), Citric (9th) and Tartaric acids (11th) in conjunction with papaya enzymes.
As an experiment, one fine day I applied half face with Ren masque and other half was taken over by Caudalie. I wanted to compare the efficacy and final results. As it turns out, they both leave my skin equally bright, luminous and radiant. I consulted with the Man of the House to ensure I’m not delusional and he concurred.
Packaging wise Caudalie is in a tube whilst Ren is in pump action plastic bottle. Easily available at Sephora and other online sites. From a price perspective, I believe Caudalie is more value for money (75ml 2.5fl oz $39). Ren appears to be tad steeper at $59 for same quantity as Caudalie. They have a smaller size available at 50ml 1.7fl oz however it would make more sense to indulge in the bigger size at $4 extra you’d get whopping 75ml!!! Unsure what logic was applied at the pricing structure. 
What have your experiences been with each of these masks?

  1. I liked the REN mask but I wasn’t blown away by it… I guess I was just disappointed after all the hype it got. I dind’t like the way it smelled, but it was tolerable – I thought it smelled like rotting oranges and play-doh. And the muslin cloth that they provide (or did provide, not sure if that’s still a thing) with the mask is literally pointless. xD I love the Caudalie masks I’ve tried (the moisturizing one and the purifying one), so now I need to get the glycolic one after reading your review! 😛

    1. Hahaha love your smell description for Ren mask. It’s spot on!! Caudalie mask is lot more gentler but I love how it smells and how it leaves my skin. Directions of use on Sephora site says to remove with grape water, unless I douse myself in wine I don’t have the patience to stand there spritzing grape water to rinse. Tad excessive tbh. Would love to know how you get on with Caudalie mask😊

      1. LMAO, I’m glad you agree! So many people were like “it smells like orange marmalade!” and then I smelled it was like WTF? 😛 ❤ I will probably buy the mask at the next VIB sale. 😉
