    Not sure

    Consistency is runny and is sticky on application. I find other Inkey serums are sticky too and am not a fan of that. Instructions say use a pea size amount so that’s impossible to guage as it’s runny. Unsure of effect yet.

    Collagen peptide serum.

    Love this product. Light serum easily absorbed into the skin.. makes my skin feel hydrated and smooth. Out of stock for a while so delighted when it came back.

    Consistent repurchase

    I added this to my routine around 12 months ago and have continued to buy it ever since. It has a lightweight texture that layers really well and leaves my skin feeling plump and hydrated without any heaviness. It’s an easy, reliable step in my routine and one I wouldn’t skip now
