The ingredients in AVA and NORA weren't chosen for marketing. They were chosen because published research supports their use specifically for melanin-rich skin — skin that responds differently to standard exfoliants, and that has historically been underrepresented in clinical studies.
Why ingredient selection matters more for deeper skin tones
When skin inflames, melanocytes — the cells that produce pigment — respond by producing more melanin. On melanin-rich skin, this response is stronger and more persistent. The result is post-inflammatory hyperpigmentation (PIH): dark marks that can outlast the original irritation by weeks or months.
This means that for deeper skin tones, the speed and depth of an active ingredient's penetration directly affects whether it helps — or creates a new problem. An ingredient that works well on lighter skin can trigger PIH on melanin-rich skin simply because it penetrates too quickly, causing micro-inflammation that the skin's pigment system interprets as damage.
A 2024 systematic review published in JAAD International confirmed this gap: research on PIH treatments has historically centered on lighter skin tones, leaving limited evidence-based guidance for darker skin. The review found that aggressive treatments frequently worsen outcomes in skin of color due to stronger inflammatory responses.

Used in: AVA Resurfacing & Soothing Body Toner
Most body exfoliants use glycolic acid — the smallest AHA molecule. Its small size means it penetrates quickly and deeply, which is effective for skin that tolerates irritation well. For melanin-rich skin, that rapid penetration often triggers enough inflammation to cause new PIH — replacing one dark spot with another.
Mandelic acid has a significantly larger molecular structure than glycolic or lactic acid. This means slower, more controlled penetration — effective exfoliation without the inflammatory spike. A clinical study published in the Journal of the American Academy of Dermatology assessed mandelic acid in subjects with melasma, a form of hyperpigmentation common in deeper skin tones. After 4 weeks of treatment with a 10% mandelic acid formulation, subjects showed a 50% improvement in melasma severity with minimal side effects.
AVA uses mandelic acid at a pH of 3.73 — the optimal range for AHA efficacy — combined with Centella Asiatica Extract, Aloe Barbadensis, Panthenol, and Allantoin to calm the skin during exfoliation and reduce any residual inflammatory response.
Journal of the American Academy of Dermatology →Bakuchiol — retinol results without the irritation
Used in: NORA Bio-Restorative Dry Body Oil
Retinol is one of the most studied ingredients for skin renewal and pigmentation. It works — but it comes with a significant side effect profile: scaling, stinging, and photosensitivity. For melanin-rich skin, these side effects are particularly problematic because they trigger the inflammatory response that causes PIH.
Bakuchiol is a plant-derived compound that activates similar gene expression pathways to retinol, producing comparable effects on skin renewal and pigmentation through a gentler mechanism. The most cited clinical study (Dhaliwal et al., 2019), published in the British Journal of Dermatology, compared 0.5% bakuchiol applied twice daily to 0.5% retinol applied once daily in a randomized, double-blind 12-week trial of 44 subjects.
Results: both compounds significantly reduced wrinkle surface area and hyperpigmentation, with no statistically significant difference between them. The retinol group reported significantly more scaling and stinging. The bakuchiol group reported no adverse effects.
For skin prone to PIH, this distinction matters. Bakuchiol supports skin renewal without triggering the irritation cycle that creates new dark marks.

Used in: NORA Bio-Restorative Dry Body Oil
Standard salicylic acid is water-soluble, which limits how deeply it can penetrate a hair follicle that is lined with oil. LHA (Capryloyl Salicylic Acid) is a lipophilic — oil-soluble — derivative of salicylic acid. This means it travels through the follicle's own lipid environment, reaching the buildup that causes ingrown hairs and KP bumps at their source.
Because LHA works inside the follicle rather than on the skin surface, it exfoliates more precisely with less surface irritation — making it a better fit for skin that is prone to inflammation. Clinical research comparing LHA to glycolic acid found LHA produced a 46% improvement in pigmentation versus 34% with glycolic acid, with better tolerability.
In NORA, LHA is used at 0.30% — a low, well-tolerated concentration that is effective without causing surface irritation.
