Using several serums in the same skincare routine is possible, but more products do not necessarily produce better results.
Some ingredients can work well within the same routine, while combining several potent active ingredients may increase dryness, stinging, peeling, or irritation.
For example, someone might use a hydrating serum alongside another serum targeting pigmentation. However, combining multiple exfoliating acids, retinoids, or other potentially irritating products requires more caution.
Instead of building a routine around as many active ingredients as possible, identify your main skin concern first.
A simple, consistent routine containing a few appropriate products is often easier to tolerate and maintain than an overly complicated routine.
