Your Questions Answered

Here are answers to common questions about using this AHA essence, from how it fits into your routine to what you can expect for different skin types. Understanding these details helps you use the product with confidence for the best, gentlest results.
Begin by using this essence 2-3 times per week in the evening after cleansing and before your toner. Apply a few drops to dry skin, gently patting it in. Wait 1-2 minutes before proceeding with the rest of your routine. If your skin is new to AHAs, start with once a week to assess tolerance.
Yes, this essence is formulated to be suitable for sensitive skin. The blend of acids is designed for gentle exfoliation, and the inclusion of Chestnut Seed Extract helps support the skin barrier. However, we always recommend patch testing any new active product and starting slowly to see how your skin responds.
Wearing a broad-spectrum SPF 30 or higher every morning is essential when using any AHA product. AHAs can increase your skin’s sensitivity to the sun, making it more susceptible to sunburn. This daily protection is crucial to protect your newly revealed skin and maintain your results.
Individual results vary, but you may begin to notice a smoother texture and brighter tone within 2-3 weeks of consistent use. For more significant improvements in skin clarity and tone evenness, continued use over 6-8 weeks is typically recommended as part of a regular routine.
If you experience persistent irritation, redness, or discomfort, discontinue use immediately and allow your skin to recover. It’s important to listen to your skin. When you reintroduce exfoliation, consider using the product less frequently or opting for a lower concentration to better suit your tolerance level.
This essence is designed to complement hydrating and barrier-supporting products. It works well with gentle, fragrance-free formulas. Avoid using it simultaneously with other strong actives like retinoids or high-concentration Vitamin C in the same routine to minimize potential irritation and allow each product to work effectively.
