How do I know if this product is suitable for my skin or hair type?
Our products are formulated to target specific concerns while remaining gentle across various types. You can check the “Targeted Concerns” and “Key Ingredients” sections on this page to ensure compatibility with your goals. If you have hypersensitive skin, reactive scalp, or known allergies, we always recommend conducting a 24-hour patch test behind your ear or along your jawline before full application.

When and how often should I use this in my routine?
Usage depends on the active potency of the product:
- Daily Essentials (Cleansers, Toners, Moisturizers, SPF, Shampoos): Suitable for daily use (AM, PM, or both, as indicated on the label).
- Targeted Treatments & Actives (Exfoliators, High-Concentration Serums, Scrubs): Best introduced gradually—start 2–3 times a week, increasing frequency as your barrier builds tolerance.
Detailed step-by-step instructions and routine placement (AM vs. PM) are outlined in the “How to Use” tab on this page.
Can I layer this with other active ingredients or products from different collections?
Can I layer this with other active ingredients or products from different collections?
Yes, most of our collections are designed to work synergistically. However, when layering potent active ingredients (such as AHAs/BHAs, Retinol, or high-strength Vitamin C), avoid applying multiple strong exfoliants or acids in the exact same routine step to prevent barrier irritation. Alternate their use between morning and evening routines or across alternate days.
How should I store this product to maintain its freshness and potency?
How should I store this product to maintain its freshness and potency?
Store all bottles and jars in a cool, dry place away from direct sunlight, humidity, and excessive heat (keep tightly capped when not in use). For products containing unstable actives like pure Vitamin C or antioxidant-rich botanical oils, keeping them in a dark cabinet helps preserve maximum ingredient stability and shelf life.
