What you get: A powerful, targeted scar reduction serum with our highest level of Retinol (1%) to help fade the look of marks, reduce wrinkle depth and smooth uneven skin texture.

Why it works: 1% Retinol helps to resurface skin and target the appearance of persistent scarring and deep wrinkles. 5% Apricot Kernel Oil and 2% Squalane support the skin barrier and help prevent moisture loss.

    Not sure

    I have been using this one for a very long time but I don't know if the formula recently changed. Recently it doesn't seem to be doing much for my skin which is sad because a year ago it was doing wonders but recently I haven't been getting the same result, it used to be like an eraser of imperfections but lately not at all.... I might give it a rest and try again, just to see what happens.

    Hi Nancy,

    Thank you for taking the time to share your honest feedback about our 1% Retinol Serum, and for being such a loyal customer who has used it for a very long time. We're truly sorry to hear that you're not experiencing the same wonderful results you used to see, especially when it was working so effectively for you a year ago.

    We understand how disappointing and frustrating it must be when a product that once delivered such impressive results seems to have stopped working the same way for your skin. It's particularly disheartening when you have that positive history with the product and were expecting to continue seeing those same benefits.

    We want to reassure you that we haven't made any recent changes to our 1% Retinol Serum formulation. Sometimes skin can become accustomed to active ingredients over time, or changes in factors like hormones, climate, stress, or other products in your routine can affect how your skin responds to retinol. It's also possible that your skin's needs may have evolved after consistent long-term use.

    Your approach of giving it a rest and trying again is a good idea - sometimes taking a break from retinol and then reintroducing it can help restore its effectiveness. We truly value your feedback and your loyalty to the product, even during this challenging period with the results.

    Please do reach out to our askINKEY Team if we can support you further with your experience 🖤
