1. Use sea buckthorn water as the primary base instead of relying only on purified water to create a clear botanical differentiation point.
2. Build a multi-pathway tone-care concept around Niacinamide + Tranexamic Acid + a stabilized Vitamin C derivative.
3. Target a gentle daily-use sensorial profile: fast absorption, low stickiness, no greasy film, and comfortable layering under moisturizer or sunscreen.
4. Add Centella, Panthenol, Beta-Glucan, Ceramide NP, and Hyaluronic Acid derivatives to balance brightening care with hydration and soothing support.
5. Consider a formula without artificial color or added fragrance for a sensitive-skin-friendly positioning, subject to stability and safety testing.
6. Recommended package: compact square amber-glass 30 ml dropper bottle with a white ribbed collar and white rubber bulb. Use original botanical artwork and avoid third-party brand names, product names, logos, and copied label text.
7. Recommended content color: naturally clear to pale golden. Avoid strong artificial orange coloring.
8. Validate all percentage, brightening, dark-spot, sensitive-skin, vegan, clinical, and free-from claims through final formula review and applicable testing before sale.
