Technical question about Sunday Riley Luna...

[supervixen1982]

Does anyone know what the percentage of retinol is in the Sunday Riley Luna? I'm comparing it to the Peter Thomas Roth Retinol Fusion PM and Dr Dennis Gross. TIA

I have been searching for an answer and cant find one. It does contain green and purple dye though, and array of Essential Oils. The retinol in Sunday Riley is Trans Retinol Ester which is different than the Retinol l normally found in skincare and has not been as exstensively tested. I personally use Luna, and it does work well for me so I’ll finish the product that I have, but I won’t repurchase it because I think I can find a retinol product with better ingredients (ie. no dye) and more transparency.
