Masking Vinegar Smell of Collagen in Anti-aging Serum

Question

I am formulating an anti-aging serum that contains collagen. It has a strong vinegar-like smell. How can I mask this odor effectively? Are there specific ingredients like Citromask™ or cosmetic-grade fragrances that can help, and how should they be used in a leave-on facial serum?

Regarding masking the vinegar-like smell of collagen in your anti-aging serum formulation, here are the recommended approaches:

Reduce Collagen Concentration: Lowering the percentage of collagen in your formula is the most direct way to decrease the intensity of its natural odor.
Incorporate a Masking Agent: You can use an ingredient specifically designed to neutralize or mask odors in cosmetic formulations, such as Citromask™.
Add a Cosmetic-Grade Fragrance: A small amount of fragrance can help cover the smell. It is crucial to select a fragrance that is specifically designed and approved for use in facial skincare products to ensure safety and minimize potential irritation.

Ensure any masking agent or fragrance you choose is suitable for leave-on facial applications.
