It comes down to your main goal. Our Copper Peptide and Vitamin C serums already include hydrating formulas, so you may prefer to stay with those. Many people reach for the Hydrating Serum when they want an extra layer of hydration, or want to keep a gentler option on hand for more sensitized periods.

Choose the Hydrating Serum if your skin feels tight, dry, or flat and you want lightweight, lasting hydration, or a gentle option for when skin feels reactive.

Choose the Copper Peptide Serum if your focus is firmer-looking skin and supporting elasticity.

Not sure? Any of them work as your hydration base. The Hydrating Serum is the lightest, most sensitive-skin-friendly of the group, and it layers well with the others if you want to combine.
