Combining skincare products can mean layering products or alternating frequently from one brand to another, such as using one product every other day. Of course, you can mix and match your skincare product lines. Your skin doesn't know or care what brands you use. Never mix brands if they contain retinol, glycolic acid, salicylic acid or peptides.
The amount of retinol that the skin can actually absorb is limited, so don't torture it. Like all myths, this one also has its share of truth. I work for a mineral makeup company with a really great skincare line, so I only use their products because they are the first thing that has worked really well for me. These types of skincare products are usually made for everyone's pocket and for more widespread use, as they are cheaper and quite accessible. For example, if you have oily skin and you choose a set of products from the same line, they will treat your skin properly and cover all parts of your skincare regimen.
When it comes to mixing different brands, it's usually a gray area because you never know for sure which option is best for you. No two skins are the same, so there's no guarantee that what works for one person will, in fact, also work for you. Buying skincare products can be overwhelming. In addition to the wide range of brands sold in physical stores, there are even more online options.
For example, that serum can do wonders for your skin, but the moisturizer from the same line is too rich for your skin type and makes you sprout.
