    "I really love this duo. Finally seeing good results after battling with acne for 6+ months and trying out dozens of producs. Definitely recommend for anyone who is fighting with acne and stubborn dark spots. Faded mine within weeks. Still have a few spots, but still a HUGE difference. These photos were taken a month apart."

    "Never leave reviews but this product has transformed my skin. Went from congested skin, cystic spots, trapped pores and whiteheads & redness to clear and smooth skin. My skin does not breakout anymore and redness is reduced a lot! I have attached photos that I have used for tracking - 2 month difference. Been using this alongside the salicylic acid cleanser."

Reviews Summary
Customers say this treatment absorbs quickly and feels gentle on the skin. Many reviews mention gradual improvements in skin texture and appearance over time, with results typically showing after several weeks of consistent use. While some notice changes within days, others report needing 1-2 months for visible results. The cream-like texture receives frequent praise for its easy application. Some note the small product size as a limitation, though many find a little goes a long way. Reviews are mixed on effectiveness, with most reporting positive outcomes while a few see minimal changes. Those who stick with regular use often become repeat purchasers.

    Almost deleted my daughter's scar

    My daughter started using mandelic acid on a scar on her arm, the difference in 2 weeks is amazing, I have reordered! My daughter is diabetic and she uses the Libre sensor, there are always scars so I am so happy I found a product that works.
