"They suggest using the Half and Half as a moisture sandwich with their retinaldehyde, which I 10 out of 10 recommend. That has to be one of my favorite Prequel products and they have a lot of great gems. Retinaldehyde can be a little irritating in the beginning, although it's generally well tolerated, and I find the base of that retinaldehyde is amazing as a moisturizer, it's beautiful. That has to be one of the best products I have tried out this year, I'm not exaggerating. It's going to make an appearance in my best of series most likely towards the end of the year."

"I dropped her down to the retinaldehyde from Prequel, which is a newer product, and it's less intense. And she's tolerating it now beautifully. She's so happy with how her skin is doing. I do this all the time for my patients. I will transition them from tretinoin down to retinol or retinaldehyde. It's the whole reason with Prequel I wanted to create a retinaldehyde product because I had so many patients struggling to tolerate their tretinoin either on their face or on their neck and chest. And I wanted them to have options where they could still be really successful and see great anti-aging benefits but not put their skin through it constantly with tretinoin."
