Vitamin C offers flexibility in application timing—it can be effectively used in either your morning or evening skincare routine. When applying vitamin C in the morning, always follow with a broad-spectrum sunscreen to help protect skin and prevent UV damage. Some may also prefer to use Vitamin C Suspension 23% + HA Spheres 2% or Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F at nighttime due to their oilier texture.
For those new to vitamin C skincare, we recommend starting with lower concentrations and gradually increasing strength as your skin builds tolerance.
When incorporating vitamin C into your routine, certain ingredient combinations require careful consideration. Direct vitamin C should not be used simultaneously with niacinamide, as this can compromise the stability and efficacy of both ingredients.
Similarly, avoid using direct vitamin C alongside direct acids or strong retinoids, as this combination may lead to increased sensitivity or irritation. If you wish to use these ingredients in the same skincare routine, allow sufficient time between applications. For example, you might use vitamin C in the morning and retinoids in the evening.
