Is it Possible to Use too Many?
Wondering if layering too many serums could do more harm than good? The answer is complicated. An excess of serums isn't necessarily a bad thing. However, an excess of the wrong kind of serum may lead to problems. For example, gentle, hydrating serums like hyaluronic acid and antioxidant serums are fine to layer, but a surplus of comedogenic or exfoliating acids can lead to clogged pores, breakouts, and irritation.
