Making salicylic acid serum at home fundamentally begins by preparing the salicylic acid itself for cosmetic use. According to the provided information from a video titled "DIY Salicylic Acid Solution and Serum," salicylic acid comes in the form of a fine, white powder.
Understanding the Starting Material
Before you can create a liquid formulation like a serum, it's crucial to know the form of the active ingredient. Salicylic acid, as noted in the source, is typically a powder.
The Essential First Step: Dissolution
You cannot use the salicylic acid powder directly on the skin in this form for a serum application. The reference explicitly states, "we need to dissolve it in a solvent to use it for cosmetic."
- Salicylic Acid Form: Fine white powder.
- Requirement: Must be dissolved before cosmetic use.
- Method: Dissolve in a suitable solvent.
This initial step of dissolving the salicylic acid powder in a solvent is the necessary foundation for creating any liquid formulation, including a serum, from the raw powder. The reference highlights this critical requirement for starting the process.
While the referenced information specifically points out the need to start with powder and dissolve it in a solvent, creating a full serum formulation typically involves selecting an appropriate solvent (or blend of solvents, as salicylic acid isn't highly water-soluble), determining the correct concentration, and often incorporating other ingredients like humectants, thickeners, and preservatives to create a stable and effective product. However, based solely on the provided snippet, the key takeaway for making a serum starting from powder is the fundamental requirement of dissolving the powder in a solvent.
