Formulas built to work together
Vitamin C treats and protects in the morning. The Repair Serum locks in every benefit and restores overnight. Each amplifies the other.
One order, complete routine
No separate checkouts. One decision, one delivery — your morning and night routine arrives together.
Skincare works in routines, not single products.
Dermatologists consistently recommend pairing an active treatment with a deep hydrator. That's exactly what this duo is — Vitamin C treats while Hyaluronic Acid seals. You're not buying more. You're buying it right.
Protect. Hydrate. Restore.
Two serums. One complete ritual — brighter, plumper, and protected skin, morning and night, at exceptional value.
Compatible with your full routine.
Both serums are lightweight and fast-absorbing. The Vitamin C Serum is ideal for the morning. The Repair Serum can be used both AM and PM. Avoid combining Vitamin C with strong exfoliating acids or retinol in the same routine.
Do I have to use both serums every day?
For best results, use the Vitamin C Serum every morning and the Repair Serum both morning and night. Consistency is key — visible improvements in brightness and hydration are typically noticeable after 4–6 weeks of daily use.
Is this duo suitable for sensitive skin?
Yes. Both formulas are dermatologically tested and gentle. If you're new to Vitamin C, we recommend patch-testing on a small area first. The Repair Serum is hypoallergenic and non-comedogenic, safe for all skin types including sensitive and acne-prone.
Can I use the duo if I have oily or combination skin?
Absolutely. Both serums have lightweight, oil-free textures that absorb quickly without leaving a greasy residue. The Repair Serum's non-comedogenic formula won't clog pores and helps balance the skin's appearance.
How long before I see results?
Many users notice improved hydration from the very first application of the Repair Serum. Brighter, more even-toned skin from the Vitamin C Serum typically becomes visible after 4–6 weeks of consistent daily use.
Can I apply makeup on top of both serums?
Yes. Allow both serums to be fully absorbed before applying makeup. Their lightweight textures create an ideal hydrating base that helps makeup sit more smoothly and last longer throughout the day.
Why does the Vitamin C Serum change color over time?
This is completely normal. Vitamin C naturally oxidizes when exposed to light and air. The serum remains fully effective. Store it in a cool, dry place away from direct sunlight to preserve its potency.
