Review on Zo Skin Health RADICAL NIGHT REPAIR Serum 60ml - Boosts Skin Health and Repair with 2fl oz Size by Heidi Wilson

I did some research on retinol, spoke to a dermatologist and decided on this product after comparing many on the market, one final word : BEST. I'm sad that a lot of people think it gives them allergies if it rips off your old skin like retinol does when you first use it. Therefore, the only way to get the most benefit from retinol is to develop a tolerance. I suggest trying a small amount (the size of a pea) for the first time and waiting at least 48 hours before using again (retinol builds up in your skin over 48 hours). If your skin is scaly (99% of the time), stop for a week and then start again. Apply it once every 48 hours until you develop full tolerance, then you can do it daily. You will see amazing results within a month and even greater anti-aging effects in the long term. Hope that helps!
