- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- Application of 15% azelaic acid gel significantly reduced post-inflammatory erythema and hyperpigmentation, decreased hemoglobin and melanin content, improved quality of life, and contributed to acne improvement in patients with mild to moderate acne compared to placebo. ([Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/))
- Azelaic acid nanocrystal hydrogel 10% achieved a higher success rate and greater lesion reduction than azelaic acid cream 20% in patients with mild to moderate facial acne. ([Pharmaceutics, 2021](https://pubmed.ncbi.nlm.nih.gov/33923739/))
- Cruelty-free extracted snail slime promotes fibroblast viability, triggers recovery through Erk protein activation, reduces cyclooxygenase-2 expression, and increases angiopoietin 1 gene expression and collagen I release in skin cell populations. ([Molecules, 2023](https://pubmed.ncbi.nlm.nih.gov/36770889/))
- Topical application of a dermocosmetic containing Myrtus communis extract and azelaic acid reduced acne relapses and helped maintain remission compared to a light moisturizing cream in adult females in the acne maintenance phase over 16 weeks.
