The 15% off Glycolic Lotion, a retinol-based lotion, has been praised by reviewers for its ability to make their skin look 30 years younger and prevent crepey and sagging skin around their upper arms. Reviewers claim that the product has resulted in a significant increase in results for smoothing and hydrating my skin. One reviewer credits the cream for making their skin appear more firm and plump. Another reviewer, KatM, found the product after using it for just two days and said it made her arms feel summer-ready. She also found Eucerin Advanced Repair cream as a regular moisturiser.
