    "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 effectively addresses skin marks and texture concerns. Many notice improvements in skin smoothness and spot fading within weeks of consistent use. While some report quick results overnight, others mention gradual changes over longer periods. The gentle formula absorbs well and feels comfortable on the skin. Some users note the quantity seems small for the price, and a few haven't seen their desired results yet. Most find it works best with regular nightly application.

    It’s alright

    I used this for a few months on my forehead where I had hyperpigmentation scars , even though I did find them fading overtime in a few months , I’m not sure if it was due to other skincare products or this alone . A tube lasted a few months for targeted treatment but if your going to use this on your whole face , it’s going to run out sooner obviously, so bear that in mind alongside the price tag .

    Nice for marks

    It's good if you have red marks but it takes some time to see results, it's not wonderful but it kinda works.
