Frequently Asked Questions
Common questions about skincare ingredients, layering, safety, and routine building.
It’s a quick-reference ingredient guide. Use it to understand what an ingredient does, what it’s commonly used for, and when you may want extra caution.
Match ingredients to your main goal:
- Dry/dehydrated: Hyaluronic Acid, Squalene, Ceramides.
- Oily/congested: Salicylic Acid, Niacinamide.
- Sensitive/irritation-prone: Ceramides, Green Tea (and introduce actives slowly).
Sometimes yes — but stacking actives is where irritation lives. Keep it simple, especially when starting:
- Often works well: Vitamin C + Ferulic Acid; Niacinamide + Hyaluronic Acid.
- Use caution: Retinol + AHA/BHA in the same routine can be too much for many people.
Some ingredients (like retinoids) are typically avoided during pregnancy. Always check with your healthcare professional for guidance specific to you.
Stop the new product, simplify your routine, and focus on barrier support. If symptoms persist or are severe, consult a qualified professional.
