Key ingredients in asa skin dark spot serum
Vitamin C (3-O-Ethyl ascorbic acid):
This stable form of Vitamin C is known for its exceptional brightening properties. By inhibiting tyrosinase, an enzyme crucial for melanin production, Vitamin C helps to reduce existing dark spots and prevent new ones from forming. Research shows that Vitamin C at concentrations up to 20% can effectively fade hyperpigmented spots, with optimal absorption and stability achieved through its ethyl ascorbic acid form (1,2).
Niacinamide:
As a versatile and well-tolerated ingredient, Niacinamide offers multiple skin benefits. It reduces the transfer of melanin to the skin’s surface, diminishing the appearance of dark spots. Additionally, Niacinamide strengthens the skin barrier, improves elasticity, and reduces inflammation. Studies have consistently shown Niacinamide’s effectiveness in reducing hyperpigmentation, with significant results observed in both clinical and real-world settings (3,4).
Tranexamic acid:
Known for its efficacy in treating stubborn hyperpigmentation conditions like melasma, tranexamic acid works by inhibiting the by inhibiting tyrosinase. This ingredient is particularly effective for individuals with darker skin tones, who are more prone to hyperpigmentation. Clinical studies have demonstrated the effectiveness of 3% Tranexamic Acid in safely reducing melasma and improving skin tone (5).
Clinically proven results and safety
To ensure our serum meets the highest standards, we conducted a comprehensive consumer trial involving women of colour aged 18 to 40 with dark brown skin (fitzpatrick skin types 5 and 6). Over a four-week period, participants reported a visible reduction in dark spots and an overall improvement in skin tone. The serum achieved an average user rating of 3.82 out of 5, reflecting high levels of satisfaction and effectiveness.
Additionally, our serum underwent rigorous safety testing, including a 96-hour patch test to assess potential for skin irritation. The results confirmed that the serum is safe for regular use, even on sensitive skin, with no adverse reactions recorded during the consumer trial.
