I use an amazing serum. Vegan certified no chemicals plant based Constancesergio.arbonne.com

It depends on what's in them? Some are fluff ingredients, some are hormone disrupters and some are actually great natural ingredients. We use natural ingredients backed by science. Rooibos tea is one of the stars. Has a ton of benefits for the skin.

For most people no. There is almost no logical reason a person needs more than 2 serums (antioxidant for day and then depending on your primary skincare concerns a targeted one for nighttime). Anything else is typically excessive and you are duplicating ingredients which can actually lead to skin irritation or sensitization. Are you try to pick a serum that makes since for your routine?

Yes!!
