How do I personalize for different skin types or preferences?

As a beauty and skincare brand owner, I've been struggling to create a truly personalized shopping experience for my diverse customer base. Every customer has unique skin concerns - some have oily skin, others are dealing with sensitivity, and many have combination skin types. My current approach feels like a one-size-fits-all solution, which means I'm likely losing potential customers who don't see themselves represented in my standard product recommendations. I've watched customers browse my site, add items to cart, and then abandon their purchase because they're unsure if the product matches their specific skin needs. This isn't just about product selection; it's about making each customer feel understood and valued. I want a solution that can dynamically adjust recommendations based on individual browsing behavior, past purchases, and subtle signals of skin type preference. My goal is to create an experience where a customer with acne-prone skin sees different highlighted products and offers compared to someone managing dry, mature skin. Traditional product filtering isn't enough - I need intelligent, behavior-driven personalization that feels intuitive and helpful, not invasive or generic.
