Back to Basics: How to Build a Regimen

We know conflicts can seem intimidating, but they aren’t! There are two types of conflicts: conflicts of ingredients and conflicts of tolerance, but for simplicity’s sake, we’re going to treat them the same.

We’re also going to make a distinction between a regimen and a routine. When we say regimen, we’re talking about the whole skincare process, including AM & PM and may span multiple days. A routine, on the other hand is just the products that are used in one application - so the AM routine or PM routine.

Let’s dive into conflicts. Take for example Vitamin C and Niacinamide - two active ingredients we don’t recommend using together in the same routine. The key word here is routine. You can use Niacinamide 10% + Zinc 1% in the AM routine and Ascorbyl Glucoside Solution 12% in the PM routine—just not together in the morning or evening.

If your current regimen is more complex and contains multiple conflicting ingredients, this is when you might start changing your routines by day. On the first day, you might be using Antioxidants and Direct Acids, on your second day you might be using Peptides, and on the third day, Vitamin C… and so on. It’s perfectly okay to rotate products.
