I. Pain Point Analysis: Why Ordinary Products Fail?
Before developing the treatment plan, we identified 3 core problems for this client:
Complex Pigmentation: Flaky Melasma and Age Spots Treatment on the cheeks combined with a few age spots around the eyes, indicating deep-seated pigmentation.
Fragile skin: Overall yellowish and dull complexion, with increased pigmentation after sun exposure, accompanied by slight redness and inflammation. Ordinary high-concentration whitening products easily cause irritation.
Previous attempts: She had tried many whitening serums, but due to single ingredients and poor absorption, the results were consistently unsatisfactory.
II. The Core Solution: Why Arbutin + Vitamin C?
Addressing the pain points mentioned above, our core strategy for her was:
"Inhibiting melanin production at the source + Reducing pigmentation + Repairing the skin barrier"
Our self-developed product, OTESALY® Skin Whitening Solution, scientifically combines these two classic whitening ingredients to achieve a synergistic effect of 1+1>2.
1.α-Arbutin: Precise Melanin Inhibition, Targeting the Source of Dark Spots
As the mainstay ingredient, we selected the more stable α-Arbutin. It penetrates the dermis to inhibit tyrosinase activity, blocking Melanin Suppression at the source. Its inherent anti-inflammatory properties soothe irritation and repair the skin barrier, ensuring a mild, non-irritating process.
2.Vitamin C: Antioxidant Brightening, Synergistic Enhancement
Vitamin C is the golden partner in skin brightening. It enhances Arbutin's control over melanin and uses reduction reactions to perform Pigment Correction, turning dark pigments lighter. Furthermore, its powerful antioxidant capabilities effectively improve sallow complexions.
3.Synergistic Effect: 1 + 1 > 2
We precisely control the concentrations of both ingredients to achieve synergistic effects in multiple dimensions, including melanin inhibition, reduction, antioxidation, anti-inflammation, and moisturizing.
Hyaluronic acid is also added to promote absorption and lock in moisture, acting as a deep penetration carrier, allowing active ingredients to reach the dermis directly, making the skin fuller and brighter while fading dark spots.
