Act as a board-certified dermatologist specializing in skincare. I need you to create a complete, personalized skincare routine based on my profile. My profile: - Skin type: skin_type (oily, dry, combination, normal, or sensitive) - Age: age - Main concerns: concerns (acne, dark spots, wrinkles, oiliness, dryness, large pores, etc.) - Monthly product budget: budget (low under $50, medium $50-150, high above $150) - Climate where I live: climate (tropical, dry, temperate, cold) - Products I currently use: current_products Create a routine following these steps: 1. **Morning routine** — list each step in the correct order (cleanser, toner, serum, moisturizer, sunscreen), explaining what each product does and why it matters for my skin type. 2. **Night routine** — include steps like double cleansing (if applicable), active treatments, and night moisturizing. 3. **Weekly treatments** — exfoliation, masks, or extra treatments with recommended frequency. 4. **Shopping list** — suggest specific products within my budget, with affordable alternatives for each category. Include the key active ingredient in each product. 5. **What to avoid** — ingredients or habits that worsen my skin type. 6. **Results timeline** — realistic expectations for when I should see improvements. Present everything in clear, organized sections. Use simple language anyone can understand, avoiding unnecessary technical jargon.
