    Crowd favorite

    For sure our top seller for an "intro" to retinol that won't break the bank. So many clients struggle with irritation and dryness using other "gentle" retinols and are apprehensive to try retinols. We've converted many clients into retinol believers with the C4 Retinol as it is gentle, effective and makes changes in the skin quickly.

    Amazing retinol treatment

    My client just repurchased this for the second time and even bought a second to hold onto once she runs out. This retinol is great at gently resurfacing the skin and aids in slowing down appearance of aging.
