FAQ.

For the curious.

You asked, we answered.

How often should I use the Stem Cells & Collagen Rejuvenating Mask?

For best results, we recommend using the mask 1–2 times per week. Bentonite clay helps draw out excess oil and impurities from the skin, while collagen and stem cell ingredients support hydration and skin renewal. Using the mask regularly can help keep pores clean and skin feeling refreshed.

If you have oily or acne-prone skin, the mask can be used up to 2–3 times per week. For sensitive or dry skin, we recommend using it once per week to avoid over-drying.

Always follow with a moisturizer after rinsing the mask to help keep skin balanced and hydrated.

How often should I use the Fortifying Vita C+ Serum?

For best results, apply the Fortifying Vita C+ Serum once or twice daily, preferably in the morning and evening after cleansing. Vitamin C is especially beneficial in the morning, as it helps protect the skin from environmental stressors such as pollution and free radicals.

Apply a few drops to clean, dry skin and gently massage into the face and neck. Follow with your moisturizer and sunscreen during the day for optimal protection and hydration.

Is the Fortifying Vita C + Serum suitable for sensitive skin?

If you have sensitive skin or are new to vitamin C, start with once daily and gradually increase as your skin adjusts.
