I've been a licensed cosmetologist, esthetician and professional makeup artist for over 20 years. And although I may be considered biased because I do work for Drunk Elephant as a educater and in sales I am leaving this review and receiving nothing in return. The A - Passioni Retinol cream is one of my favorite Retinol products on the market without needing a prescription. Retinol can be super drying to the skin, especially with regular use and I use this cream nightly (I only recommend using Retinol at night) it doesn't dry me out, I use it 3-4 nights per week. You'll notice a yellow color when you disperse it because true Retinol should be yellow in color. A passioni has been listed in the top 10 Retinol creams lists by dermatologists because it's a pure pressed Retinol that gives noticeable results, with a full 1% you receive a high dose of Retinol that's easily absorbed into the skin..
