Asked by: okimpepe On: November 14, 2018 Product Type: Cosmetics

Question

I have a serum formulation containing the following ingredients and concentrations:

  • Sodium Lactate Plus 5%
  • DMAE 5%
  • Niacinamide 4%
  • Pitera 20%
  • Repair Activator 10%

Could you please evaluate the potential of this formula to cause skin issues such as clogging, acne, or irritation, particularly for sensitive skin? Is it necessary to adjust the concentrations?

Answer

Based on the ingredients provided and our team's initial assessment:

  • Clogging/Acne: Most ingredients in this serum formulation are water-soluble or used in forms that are unlikely to clog pores or cause acne for most skin types. Our team confirms that water-soluble ingredients do not clog pores.
  • Irritation: Some ingredients in this formula have the potential to cause irritation, especially for sensitive skin. Our team specifically mentioned Sodium Lactate Plus (5%) and DMAE (5%) as potential irritants. Additionally, Niacinamide (4%) can cause flushing or irritation in some sensitive individuals. The high concentrations of fermented ingredients like Pitera (20%) and Repair Activator (10%) could also potentially cause sensitivity or breakouts in some people.
  • Formula Adjustment: The formula contains several beneficial ingredients at effective concentrations. However, if you have sensitive skin or experience any redness, itching, or discomfort, it would be advisable to adjust the formula by reducing the concentrations of potentially irritating ingredients such as Sodium Lactate Plus, DMAE, Niacinamide, Pitera, and Repair Activator. We recommend patch testing the serum on a small area of skin before applying it to your entire face to see how your skin reacts.
