    "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 has a pleasant texture. Many reviews mention gradual improvements in skin appearance over time, with most seeing results within 2-3 months of consistent use. While some notice changes within days, others report needing longer to see effects. The gentle formula receives frequent praise. Common feedback includes its effectiveness on uneven skin tone, though patience is key as results vary. Some note the small product size relative to price. Reviews are mixed on speed of results, with most emphasizing the importance of consistent, long-term use.

    Has always worked well but I’m not sure if there’s the same amount of ingredients in each bottle

    Works good as a gentle exfoliator

    Good 😌

    Nice product that absorbs quickly. For me, the results were visible after the first use of this, though I’m sure it will vary person to person.

    A game changer

    I use it on those subborn age spots on my face and hands. After using it for 2 months I can see a big difference.
