Using Multiple Ingredients with Similar Properties

Based on the information provided, using multiple ingredients that have the same mechanism of action for a specific benefit (like whitening or anti-aging) does not necessarily increase the overall effectiveness compared to using just one. It can often lead to unnecessary cost without a significant boost in performance.

However, if you use multiple ingredients that aim for the same benefit but work through different mechanisms, they can often work together synergistically, leading to improved effectiveness.

For example, combining ingredients that work via the same mechanism, such as:

• Activated Resorcinol™ (4-butyl Resorcinol) and Sym-White™ (Phenylethyl Resorcinol) for whitening.
• Syn-Coll (Palmitoyl Tripeptide-5) and Matrixyl 3000 (Palmitoyl Oligopeptide, Palmitoyl Tetrapeptide-7) for anti-aging collagen stimulation.

These combinations, where ingredients share the same working principle, are less likely to provide enhanced results compared to using ingredients with complementary actions.
