Effectiveness of Whitening and Melasma Formulas for Commercial Sale

Based on the revised formulas incorporating the staff's suggestions for stability and preservation:

• Skin Whitening Formula: This formula includes Sym-White™ (Phenylethyl Resorcinol), which is a known skin brightening agent. Combined with Snail Secretion for potential skin benefits and moisturizing, and a suitable cream base, it contains relevant active ingredients for a skin whitening product.
• Melasma Treatment Formula: This formula uses Tranexamic Acid (at the recommended maximum concentration), Kojic Acid Dipalmitate, and Snail Secretion. Tranexamic Acid and Kojic Acid Dipalmitate are widely used ingredients for addressing hyperpigmentation and melasma.

The formulas contain active ingredients commonly used for their stated purposes. Whether they are "effective enough" for commercial sale depends on the desired level of performance, target market expectations, and how the final product performs in user trials. The current ingredients provide a good foundation. Adding more ingredients isn't strictly necessary for effectiveness and could potentially complicate the formulation or stability.

Commercial success also depends on factors beyond the formula itself, such as product stability (as the staff mentioned), safety testing, packaging, marketing, and regulatory compliance.

In summary, the revised formulas contain appropriate active ingredients for skin whitening and melasma treatment. Their effectiveness for commercial sale would need to be confirmed through further testing and evaluation, but they represent a solid starting point.
