Feedback on Eye Serum and Face Serum Formulations with Whitening and Anti-Aging Actives

Asked by: tanik_fu On: April 02, 2014 Product Type: Cosmetics

Question

I have developed an eye serum formulation with the following components:

  • Cyclomethicone 5%
  • Silicone Gel 20%
  • Pepha-Tight® 2%
  • Warp Cream Maker™
  • Water

Could you please review this formula and advise on its suitability and any potential issues, especially for the sensitive eye area?

Additionally, I am considering using a similar base formulation for a face serum targeting wrinkles, lifting, and whitening by adding Alpha Arbutin. Is this approach suitable, and are there any other ingredients you would recommend to enhance the whitening effect?

Answer

Subject: Feedback on Eye Serum and Face Serum Formulations

Regarding your eye serum formulation and subsequent question about a face serum:

Eye Serum Formulation Feedback:

Based on the feedback provided in the thread, your proposed eye serum formulation is not recommended for use around the eyes.

  • Cyclomethicone: The primary concern raised is the inclusion of volatile silicones like Cyclomethicone. These can cause mild irritation around the sensitive eye area, which is highly undesirable given how thin the skin is there. Formulations for the eye area should prioritize gentleness.
  • Pepha-Tight®: The suggested concentration of Pepha-Tight® (2%) might be too high for the delicate eye area. It was recommended to potentially start with a lower concentration, such as 1%, as ingredients are often used at lower levels around the eyes compared to the face.
  • Texture: While not explicitly addressed in the replies, a high percentage of silicones (Cyclomethicone 5% + Silicone Gel 20%) could potentially result in a texture that feels too viscous or sticky, depending on the specific Silicone Gel used and the interaction with Warp Cream Maker™.
  • pH and Safety: The pH of the formulation was not discussed in the provided replies. Ensuring the pH is within a safe and effective range for the eye area is crucial for both stability and safety. The feedback strongly suggests the formula as is is not safe for the eye area due to potential irritation from Cyclomethicone.

Face Serum Formulation Feedback:

Regarding your question about using a similar base for a face serum targeting wrinkles, lifting, and adding Alpha Arbutin for whitening:

  • It was confirmed that using a similar base for a face serum with anti-aging and lifting properties is acceptable.
  • Adding Alpha Arbutin for whitening is also considered okay.
  • For enhanced whitening efficacy, the staff recommended adding Vitamin B3 and N-Acetyl Glucosamine in addition to Alpha Arbutin.

In summary, the original formula is not suitable for the eye area due to irritation concerns from Cyclomethicone and potentially high Pepha-Tight concentration. However, adapting a similar base for a face serum with anti-aging, lifting, and whitening properties (with recommended additions like Vitamin B3 and N-Acetyl Glucosamine) is considered viable.
