The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Australia.

Work well together

Use them together in the same routine, applying the peptides first to help your skin absorb the amino acid. The amino acid helps the peptides work better and keeps your skin well moisturized. You do not need to change anything since they work gently together.
