I was regretting not getting the purple box with the anti aging cream but No longer as my favourite product in this box is the Heimish marine care 0.03% retinol serum … it is so gentle. I jumped into skincare in 2024 with both feet and started with a 1% retinol (Inkey) that turned out to be too strong, so I had to go back to the drawing board. This is a great beginners retinol … would I purchase it again? Probably not because now my skin is used to this I am looking for the next step up, maybe a 0.1% retinol to complement my 0.02% retinal (BOJ), as I use both retinoids.
