Water-Soluble Azelaic Acid for Skin & Scalp Health

Azelaic acid is a highly valued dicarboxylic acid recognized for its ability to regulate sebum production, reduce inflammation, and enhance skin brightness. Despite its benefits, traditional forms such as pure azelaic acid and salified derivatives pose challenges related to solubility and stability. While salified versions improve solubility, they tend to be unstable over time, leading to precipitation in formulations. Furthermore, conventional azelaic acid is pH-dependent, limiting its flexibility in cosmetic and pharmaceutical applications.

AZELACTIVE® overcomes these limitations with a patented esterified form of azelaic acid combined with polyglyceryl-6, ensuring full water solubility, superior skin compatibility, and enhanced stability. Its low acid number compared to pure azelaic acid (20 vs 600 mgKOH/g), minimizes irritation while maintaining efficacy allowing for a wider cosmetic application range. Unlike traditional azelaic acid, AZELACTIVE® does not require strong solvents, does not precipitate in formulations, and remains effective at any pH level. These attributes make it an ideal choice for next-generation skincare and haircare solutions.

AZELACTIVE®: MULTIFUNCTIONAL BENEFITS

AZELACTIVE® delivers a comprehensive range of benefits for both skin and scalp health. By regulating sebum production, it helps maintain a balanced and healthy skin environment. It also works to reduce hyperpigmentation, enhancing skin tone uniformity and brightness. With its strong anti-inflammatory properties, it soothes irritation and redness, making it particularly suitable for sensitive skin. Additionally, it improves moisture retention and reinforces the skin barrier, promoting long-lasting hydration and resilience.

For scalp and hair applications, AZELACTIVE® demonstrates exceptional efficacy in combating hair loss by inhibiting 5-alpha reductase, thereby reducing DHT levels and preventing follicle miniaturization. It also regulates excessive oil production, ensuring a healthier scalp environment while soothing inflammation and irritation. These combined effects contribute to stronger, healthier hair growth and improved scalp vitality.

Improved skin tone evenness

REDUCED DARK SPOT PIGMENTATION

5% AZELACTIVE® significantly increased (***p<0.001) ITA° values by 44.4% at T28 up to 53.5% at T56, indicating a lighter skin tone and a reduction in dark spot intensity, markedly superior (**p<0.01) to the placebo, which showed only minimal variation. 
 
AZELACTIVE® effectively reduces dark spot pigmentation, contributing to a clinically relevant improvement in skin clarity and tone homogeneity.
 
These findings reinforce AZELACTIVE® role as a targeted skin-brightening ingredient, making it particularly suitable for formulations addressing hyperpigmentation and uneven complexion.

Before and after comparison of dark spot reduction using AZELACTIVE®. The left image (T0) shows the skin at the beginning of the study, while the right image (T56 Days) demonstrates a visible improvement in skin tone and reduction in dark spot intensity after 56 days.

REDUCED SEBUM CONTENT

5% AZELACTIVE® face cream significantly decreased (***p<0.001) skin sebum content by -12.8% at T28 and -14.7% at T56, showing long-term efficacy, greatly outperforming (**p<0.01) the placebo, which showed only minimal variation.
 
By effectively regulating sebum levels, AZELACTIVE® helps create a healthier, more balanced skin environment, particularly benefiting oily and acne-prone skin.
 
These findings position AZELACTIVE® as a powerful sebum-regulating ingredient, supporting its role in formulations aimed at improving skin texture, reducing shine, and preventing clogged pores.

improved skin complexion evenness

After 56 days of treatment, volunteers reported that AZELACTIVE® significantly improved skin clarity, uniformity, and overall appearance by effectively regulating sebum, reducing pigmentation, and enhancing complexion.
 
By the end of the study, 75% of participants observed visible improvements in skin brightness and tone uniformity, further confirming AZELACTIVE® ability to refine skin texture and correct discoloration.
 
These findings highlight AZELACTIVE® as a multifunctional ingredient, making it particularly effective for oily, uneven, and dull skin, where excess sebum and pigmentation concerns are prevalent.

REDUCED ROSACEA-RELATED ISSUES

REDUCED ROSACEA-RELATED ERYTHEMA

5% AZELACTIVE® face cream significantly reduced (*p<0.05 and **p<0.01) the erythema (redness) index by -5.3% at T28 and -7.7% at T56, demonstrating a strong soothing effect and mitigating the placebo irritating effect.

These findings highlight AZELACTIVE® ability to actively calm skin inflammation and redness, making it particularly beneficial for reactive and rosacea-prone skin. By reducing irritation over time, AZELACTIVE® helps improve skin comfort and resilience, reinforcing its role as a dermocosmetic solution for sensitive skin care.
