Q: Is this product suitable for daily use? A: It depends on the product type and your skin/hair tolerance. Gentle moisturizers, cleansers and sunscreens may be used daily; retinoids and exfoliating acids should be introduced gradually. Q: Can sensitive skin use it? A: Sensitive skin should patch test first and start slowly. If stinging, burning, swelling or persistent redness appears, stop use and consult a dermatologist/pharmacist. Q: Can I use it while pregnant or breastfeeding? A: For pregnancy or breastfeeding, check with your doctor first, especially if the product contains retinoids, exfoliating acids, strong brightening actives or other intensive ingredients. Q: Do I need skincare before it? A: Yes. Apply moisturizer and sunscreen first in the morning so makeup sits better and skin stays more comfortable. Q: Can I use it with retinol? A: Avoid using exfoliating acids and retinol in the same routine at first. Alternate nights and focus on moisturizer and sunscreen.
