Skincare Ingredients Guide
Key ingredients (retinol, niacinamide, hyaluronic acid) explained.
What Ingredients Should I Know?
Common ingredients include hyaluronic acid (hydration), niacinamide (barrier, tone, pores), retinol (texture, aging), vitamin C (brightening, antioxidants), and ceramides (barrier). The app's ingredient checker helps you see what's in your shelf products and how they might suit your skin type.
Use the ingredients guide when choosing products and building your routine. Match ingredients to your metrics: e.g. hyaluronic acid for hydration, niacinamide for pores and tone, retinol for texture and anti-aging.
Actives and Sensitivity
If you have sensitive skin, introduce one active at a time and patch-test. Start with lower concentrations (e.g. retinol 0.3% before 1%). Use the ingredient checker to avoid known irritants and the symptom diary to log reactions. Redness in the app can help you see if a new product is causing irritation.
