Skin Reaction to Homemade Cream with Cyclomethicone

Subject: Reaction to Cyclomethicone Silicone

Based on your experience and the staff's response:

You experienced small, non-itchy bumps on your forehead after using homemade creams. This happened when using Silky Serum Base and again when using Light Cream Maker with added Cyclomethicone. You did not experience this reaction with commercial products containing Dimethicone or natural extracts (though natural extracts felt sticky).

Here's a summary of your questions and the staff's insights:

• Is the reaction caused directly by silicone (Cyclomethicone)?
  The staff suspects you might be allergic to Cyclomethicone. However, they note that Cyclomethicone is widely used in many products you might have used previously without issue, which makes the direct cause less certain.
• Is it due to inadequate cleansing? Do you need a makeup remover?
  Inadequate cleansing typically leads to clogged pores or acne, not the type of rash you described. While silicones are not water-soluble, proper cleansing is important, but the rash is unlikely caused by just not using a makeup remover.
• Did hot weather contribute?
  Hot weather can cause rashes, and silicone allergy is possible, but these are separate issues. An allergy would likely occur regardless of the weather conditions.
• Why react to Cyclomethicone but not Dimethicone or other silicones?
  Silicones come in many different types (e.g., Dimethicone, Cyclomethicone, Cyclopentasiloxane, Cyclohexasiloxane). An allergy to one type does not mean you are allergic to all. Cyclomethicone itself can be a mix of different cyclic silicones. It's possible you are sensitive to a specific component within Cyclomethicone, such as Cyclopentasiloxane, but not to Dimethicone or other silicones.

The staff concluded that based on the information, they cannot definitively confirm the cause of the reaction and recommend further testing.
