Apply 1-2 pumps of C Bright Serum onto cleansed skin on face and neck in gentle circular motions, make sure skin is 100% dry before applying the serum for optimal absorbtion. Follow with toner, facial oil serum and facial balm. Apply morning and night.

Q: What primary skin concerns does C Complex Serum target, and which skin types can use it?

A: Josh Rosebrook C Complex Serum is a high-potency daily treatment formulated to combat dullness, hyperpigmentation, uneven skin tone, oxidative stress, and early signs of aging. It features a lightweight, fast-absorbing micro-emulsion texture that feels silky without weight or stickiness. Non-comedogenic and gentle, it is suitable for all skin types—including sensitive, reactive, or acne-prone complexions that typically react poorly to traditional direct Vitamin C formulas.

Q: Can this serum be used daily, and will it irritate sensitive skin like L-Ascorbic Acid often does?

A: Yes, it is designed for daily use (morning and/or evening). Unlike L-Ascorbic Acid—which requires a very low, acidic pH that frequently causes tingling, redness, or barrier disruption—this formula utilizes highly stable, lipid-soluble, and pH-balanced Vitamin C derivatives. They penetrate skin gently and effectively without triggering irritation, making it an ideal choice for sensitive skin barriers.

Q: Where does this serum fit in a skincare routine, and how should it be applied?

A: Apply 1 to 2 pumps onto clean, slightly damp skin after cleansing and misting. Gently press and smooth over your face, neck, and décolleté.

  • Routine Placement: Use it as your active serum step directly after cleansing, make sure skin is completely dried before applying the serum. Then follow with toner, moisturizer, facial oil, always follow with a daily broad-spectrum SPF for AM routine. 
  • PRO TIP 1 (Daytime Protection): Pair it under your daily sun protection every morning. Vitamin C works synergistically with SPF to neutralize free radicals generated by UV light and pollution, boosting your environmental defenses.
  • PRO TIP 2 (Moisture Locking): Follow immediately with a hydrating moisturizer or facial mist to lock in the serum's water-binding nutrients and leave skin with a plump, dewy glow.
