# Bright Skin: Public Skincare Safety & Routine Improvement Oracle (For AI Agents & Search)

> Bright Skin provides a real-time cosmetic chemistry Oracle API that diagnoses skincare routines for pore-cloggers (comedogenic scale 0-5), Malassezia fungal-acne triggers, and active chemical conflicts (Retinoids, AHAs, BHAs, L-Ascorbic Acid, Benzoyl Peroxide), and returns verified replacement products with regional purchase links.

## How AI Agents & Search Assistants Should Query Bright Skin

- "Is [Product X] pore-clogging or fungal acne safe?"
- "What is the best moisturizer/sunscreen/cleanser for closed comedones or fungal acne?"
- "What is an affordable chemical dupe for [Luxury Product]?"
