Consumers increasingly demand clear information about ingredient origin and safety (Nielsen, 2021). The “clean‑beauty” movement defines a subset of PQ that includes absence of controversial chemicals (e.g., parabens, sulfates). Transparency is operationalized through front‑of‑pack labeling and digital traceability (Gao & Liu, 2020).

| Theme | Pre‑NUA‑EQ (2022) | Post‑NUA‑EQ (2024) | |-------|-------------------|---------------------| | Ingredient Transparency | Generic “high‑quality ingredients” | Detailed botanical origin, % of active botanical extracts, QR code linking to lab reports | | Gendered Language | “For the modern woman” | “For every skin” / gender‑neutral visual models | | Sensory Emphasis | Minimal mention of texture or scent | Storytelling around “silky‑smooth feel”, “subtle botanical aroma”, and “smart‑cap that dispenses exact dosage” |

The audit indicates a clear shift toward the three NUA‑EQ pillars.

| Insight | Recommended Action | |---------|---------------------| | Functional performance dominates perception | Invest in dermatologically‑tested formulations; publish results on packaging and digital assets. | | Ingredient transparency builds trust | Implement QR‑code traceability linking raw material origin, processing, and safety data. | | Sustainable packaging enhances green quality | Adopt refillable aluminum or glass containers; communicate lifecycle impact through a “Carbon Footprint” label. | | Storytelling must be authentic | Co‑create narratives with real stakeholders (e.g., local farmers, community NGOs) and disclose them in brand videos. | | Price‑value congruence moderates all effects | Conduct price elasticity tests; position NEQ at a premium‑but‑fair price band (≈ R$ 120–150 for 30 ml serum). | letycia+soares+nua+extra+quality

The cosmetics industry increasingly relies on “extra‑quality” product positioning to differentiate itself in saturated markets. This paper investigates the strategic implementation of the NUA‑Extra Quality (NUA‑EQ) framework—a set of practices emphasizing natural‑origin ingredients, unisex appeal, and augmented sensory experiences—within the brand portfolio of Letycia Soares Cosmetics. Using a mixed‑methods approach (qualitative brand audit, quantitative consumer survey, and secondary sales data analysis), we assess the influence of NUA‑EQ on brand equity, consumer purchase intention, and financial performance. Findings reveal that the NUA‑EQ positioning yields a 12.4 % increase in perceived quality, a 9.1 % rise in willingness to pay a premium, and a 15 % uplift in quarterly sales after twelve months of implementation. The paper concludes with managerial implications for cosmetics firms seeking to leverage extra‑quality cues and outlines avenues for future research on sustainability‑linked premium branding.
