This duo comes with our two most foundational serums that slot into any skincare routine. Use Daily Vitamin C Serum in the morning for a brighter complexion with fewer dark spots, and Nightly Retinol Serum in the evening to help smooth the appearance of fine lines and uneven texture. Both formulas are targeted, effective, and gentle enough for daily use.

You get:

  • One full-size Daily Vitamin C Serum: A powerful brightening serum that helps promote a more even-looking skin tone.
  • One full-size Nightly Retinol Serum: A gentle-yet-effective serum that helps smooth fine lines, wrinkles, and uneven texture.

The Benefits:

  • Daily Vitamin C Serum helps brighten and promote a more even-looking skin tone.
  • Nightly Retinol Serum helps smooth the appearance of fine lines, wrinkles, and uneven texture.
  • Both formulas are hydrating, effective, and gentle enough for daily use.
  • Both formulas slot seamlessly into your existing skincare routine.

Use AM daily. Apply a dime-size amount to a clean face, neck, and décolleté, avoiding the eye area. Let the serum soak in, then follow with Ritual Oil and Moisture Rich Balm to lock in moisture. Follow with SPF.

Nightly Retinol Serum:
After Balancing Mist, gently massage a dime-size amount to forehead, cheeks, nose, and chin—avoid applying too closely to your eyes. Follow with Ritual Oil and/or Moisture Rich Balm to lock in moisture. Use PM daily.

  • A more stable and penetrable derivative of Vitamin C. This water and oil-soluble derivative remains in the skin longer without oxidizing to more effectively brighten skin, fade hyperpigmentation, and stimulate collagen synthesis.

  • Rich in antioxidants that fight free radicals known to cause aging, this highly effective emollient deeply hydrates for soft, smooth, and more even skin.

  • A gentler retinol and linoleic acid derivative that effectively treats congestion, fine lines, wrinkles, uneven tone and texture, and hyperpigmentation without the irritation typically associated with more aggressive forms of retinol.

  • A more penetrable form of hyaluronic acid absorbs easily to attract moisture for plump, hydrated skin.
