Exceeding Recommended Usage Rates for Cosmetic Powders

Regarding your question about the potential negative effects of using BB Micro Silk, Amino Silk, SiliSilk, and Polymethylsilsesquioxane above their recommended percentages, the information available suggests that these ingredients are primarily cosmetic powders designed to improve the texture, feel, and appearance of a formulation (like providing soft-focus, smoothness, or oil absorption).

Similar to the reply you received, these types of powders generally do not absorb into the skin in significant amounts. Therefore, using them at concentrations higher than recommended is unlikely to cause direct harm or negative physiological effects on the skin itself in the way that exceeding limits for active ingredients might.

However, exceeding the recommended percentages can still have negative impacts on the formulation and its performance, such as:

• Texture and Feel: Too much powder can make the product feel dry, heavy, or difficult to spread.
• Stability: High powder concentrations can sometimes affect the stability of emulsions or suspensions.
• Appearance: It might lead to a powdery finish or affect the clarity/color of the product.
• Cost: Using more than necessary increases the raw material cost without necessarily improving performance proportionally.

In summary, while using these specific powders above recommended levels is unlikely to damage your skin, it is generally not advisable as it can negatively impact the quality, feel, and cost-effectiveness of your final product.
