  • Before and after comparison
    "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."

  • Before and after comparison
    "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.

    This worked pretty well on my skin. My hyperpigmentation faded a bit while using it.

    Hormonal skin calls out for this as always got a break out that needs some after care. Use on spots as soon as they appear too. Got my son using it for his teenage skin. Does smell a bit odd, but it works.
