Hi All,
I’m searching the literature.. in terms of efficacy in anti ageing products does your experience show there is any place for retinyl palmitate or is the efficacy evidence just not there? I like that it’s stable, low s/e profile. Maybe it has a bad rap because it’s been unfairly compared at similar % in formulations to retinol and it should have been used at a higher % or at least compared to retinol as retinol equivalents? Eg 0.3% retinol to 0.6% retinyl palmitate?
@Perry?
thanks!
