Addressing Stickiness and Warming Sensation with Stabilized Vitamin C Serum and Mica Powder

Dear Customer,

Regarding your experience after mixing Stabilized Vitamin C (Natural-C Glycol™) Serum with mica powder, feeling sticky and a slight warming sensation on your face, we would like to explain as follows:

Sticky Feeling

The sticky feeling you are experiencing is likely due to the base ingredients of the Stabilized Vitamin C (Natural-C Glycol™) Serum, which contains glycols to help deliver the vitamin C into the skin. Adding mica powder, which is a solid, may not significantly reduce this stickiness and could potentially make it feel more textured.

Warming Sensation

The slight warming sensation you feel might be due to the relatively low pH of the vitamin C serum (pH range of 2-3). It is normal to experience a mild tingling or warming sensation when using acidic products, especially if your skin is sensitive or not accustomed to them. However, if the warming sensation increases or you experience other signs of irritation, we recommend discontinuing use immediately.

Important Caution

According to the product information, this Stabilized Vitamin C (Natural-C Glycol™) Serum is designed as a ready-to-use finished product and it is not recommended to mix it with other ingredients (except fragrance and color). This is because adding other ingredients may affect the stability of the vitamin C, potentially reducing its effectiveness or causing undesirable changes.

Therefore, mixing it with mica powder may have altered the properties and stability of the serum.

Recommendations

• For the mixture of Stabilized Vitamin C (Natural-C Glycol™) Serum and mica powder you have already made, if the stickiness and warming sensation are not severe and do not cause continuous irritation, you may choose to continue using it, but please observe your skin's reaction closely.
• If you wish to reduce stickiness in the future and want to mix vitamin C with other ingredients to create a custom formulation, we recommend considering other forms of vitamin C that are suitable for formulating into cosmetic bases, or consulting with a formulation expert to achieve the desired texture without compromising the efficacy and stability of the vitamin C.
• If the warming sensation or irritation worsens, you should stop using the product immediately and consult a dermatologist.

We hope this information is helpful.
