Frequently Asked Questions

Our products feature clinical-grade actives like kojic dipalmitate, alpha-arbutin, and niacinamide combined with 12+ soothing botanicals including colloidal oatmeal, calendula, and bisabolol. Each formula is dermatologist-inspired and designed specifically for sensitive skin, delivering professional-level results with gentle, skin-barrier-supporting ingredients that comfort while they transform.

Brightening and tone-correcting results typically appear after 4–8 weeks of consistent use, as your skin naturally renews itself. However, barrier repair benefits like improved hydration and reduced irritation can often be felt immediately upon application. For best results, use products consistently as part of your daily routine.

Yes, daily SPF is essential! Actives like kojic dipalmitate, alpha-arbutin, and niacinamide can make your skin more sun-sensitive as they work to brighten and renew. Always apply broad-spectrum SPF 30 or higher during the day to protect your results and prevent further discoloration or irritation.

Our formulas are specifically designed for sensitive skin with gentle, soothing ingredients. However, pregnant or nursing individuals should consult their physician before using products containing high-dose actives like kojic dipalmitate or arbutin. We always recommend patch testing and speaking with your healthcare provider about any new skincare during pregnancy.

We recommend using the Tone Correcting Stick and Bar on your body only. These formulas contain stronger concentrations of active ingredients than typical facial products and are specifically designed for areas like underarms, inner thighs, knees, and elbows. For facial concerns, consider our gentler face-appropriate options.

Keep your products in a cool, dry place away from direct sunlight to maintain their potency and freshness. For the Tone Correcting Stick and Bar, always cap tightly after use to prevent drying out. Avoid storing in hot, humid areas like bathrooms when possible, and never leave products in direct sunlight or extreme temperatures.
