I bought this and the regular triple lipid peptide cream. I was wondering if it is worth it to use both

It really depends on your skin’s needs. Using both might be too much; you may experience breakouts or more oil on your skin. If you tend to be dry, go with the cream. If you’re combo/oily, the gel. Alternatively, if you still want both, the cream may better suit you for winter and the gel as a lightweight switch in the summer.
