Modifying Yeast Serum Formula for Cost Reduction and Dropper Application

Based on the search, a specific finished formulation named "Yeast Serum" was not found in our database. However, several ingredients related to yeast or fermentation were found, which could be key components of the serum you mentioned, such as Beta Glucan (yeast extract), Yeast Radiance™, MYFerment™ Balance, and MYFerment™ Barrier.

Modifying a formulation to reduce cost by reducing or substituting certain ingredients is possible in cosmetic formulation development, but it requires careful consideration of the potential impact on:

• Formula Efficacy: Changing key active ingredients may reduce the serum's effectiveness or alter its intended results.
• Formula Stability: New ingredients must be compatible with other ingredients in the formula and not cause separation, discoloration, or odor changes over time.
• Texture: Changing the gelling agent or thickener will directly affect the serum's texture.
• Safety: New ingredients must be safe for skin use.

Regarding whether the resulting product will have a gel texture and can be put in a Dropper bottle, this depends on the type and amount of gelling agent you choose. If you use a suitable gelling agent in an appropriate amount, you can create a serum with a clear or semi-gel texture that has a suitable viscosity for use with a Dropper bottle. Generally, serums intended for Dropper bottles should not be too viscous to allow for easy drawing up and dispensing.

If you have an initial "Yeast Serum" formula that you wish to reduce the cost of, knowing the ingredients and their proportions in that formula will help in recommending more precise approaches for ingredient modification. For example, finding active ingredients with similar properties but lower cost, or adjusting the type/amount of gelling agents and humectants to control texture and cost.

In summary, cost reduction is possible but requires detailed testing and evaluation to achieve the desired product quality. It is also possible to create a gel texture suitable for a Dropper bottle if appropriate gelling agents are selected.
