Frequently Asked Questions
Q1: What is the recommended concentration for cosmetic formulation?
The recommended usage level is 2–5% of the total formulation, depending on the desired efficacy and product type. For serums, 3–4% is typical, while creams may use 2–3% to maintain stability.
Q2: How should I store bulk quantities to maintain potency?
Store in airtight, light-resistant containers at 2–8°C. Avoid repeated freeze-thaw cycles. For long-term storage, consider aliquoting into smaller volumes to minimize exposure.
Q3: Can this peptide complex be combined with other active ingredients?
Yes, it is compatible with hyaluronic acid, niacinamide, and vitamin C at low pH. However, avoid combining with high concentrations of acids or retinoids that may degrade peptides. Always perform a stability test.
