A shared goal does not mean identical use
Our day formula is a hydrogel for more even-looking tone. Vitamin C products vary in form and strength; begin in separate sessions rather than layering several unfamiliar tone-focused products.
Use the relevant wear cue
Day ☀ Kojic Acid & Turmeric Hydrogel Mask: Cleanse and pat skin dry before applying. Wear it until it turns transparent. Remove and massage in the remaining essence, then moisturise as needed. Always use daytime SPF.
Keep layering readable
Patch test and introduce one new product at a time. Separate unfamiliar strong actives at first. Stop if discomfort develops, and keep daytime SPF in the routine.
Choose a schedule, then choose boxes
The Double Duo combines 2 Copper boxes and 2 Kojic boxes: 20 masks for 10 day and 10 night rituals a month, at $199 one-time or $169/month. The first 500 subscribers are Founding Members who lock $169/month for life.
