Azelaic Acid (Liquid Azelaic™) Concentration, Side Effects, Packaging, and Cosmetic Science Career Path
Question
Based on the forum discussion about Azelaic Acid side effects and the cosmetic science career path, I have questions regarding Liquid Azelaic™ and working in the field. Could you please clarify:
- Why is the recommended usage concentration for cosmetic ingredient
Liquid Azelaic™(5-10%) lower than medical products like Skinoren Cream (up to 20% standard Azelaic Acid)? - What are the potential side effects of using Liquid Azelaic™, especially at higher concentrations, considering it's described as gentler than standard Azelaic Acid? (Reference to peeling and redness mentioned in the forum reply).
- What are the specific packaging requirements for
Liquid Azelaic™to maintain its stability, given the instruction to keep it away from sunlight and heat? Is opaque packaging necessary? - Regarding a career in cosmetic science, what are the key requirements and expectations for graduates working in companies like yours, based on the insights about the need for practical experience, continuous learning, and market understanding?
Answer
Azelaic Acid Concentration, Side Effects, and Packaging
Regarding your questions about Azelaic Acid (Liquid Azelaic™):
Concentration Differences
The product description for Azelaic Acid (Liquid Azelaic™) recommends a usage rate of 5-10%, with 10% being recommended for specific benefits like whitening, brightening, treating blemishes, and reducing facial oiliness. This particular product is a water-soluble form (Potassium azeloyl diglycinate) which is described as gentler than regular Azelaic Acid.
Medical-grade products like Skinoren Cream may use higher concentrations (up to 20%) of standard Azelaic Acid. The difference in recommended concentration between this cosmetic ingredient (Liquid Azelaic™) and a pharmaceutical product like Skinoren is likely due to the specific form of Azelaic Acid used and its intended application (cosmetic vs. medical treatment). Using higher concentrations generally leads to stronger effects but also increases the potential for side effects.
Side Effects
Azelaic Acid, including the Liquid Azelaic™ form, has an exfoliating effect. While the Liquid Azelaic™ is noted as being gentler than standard Azelaic Acid, higher concentrations can still lead to side effects such as peeling and redness, as mentioned in the forum reply you included. It's important to start with a lower concentration and observe your skin's reaction.
Packaging Requirements
The storage instructions for Liquid Azelaic™ advise keeping it away from sunlight and heat. While it doesn't explicitly state that opaque packaging is required, protecting the product from light is important for maintaining its stability and effectiveness over time. Storing it in an opaque container or away from light sources is a good practice.
Cosmetic Science Career
Regarding your question about working in a company like ours after studying cosmetic science, based on the forum reply you shared:
Graduates typically need to gain significant practical experience. The field requires continuous learning to keep up with new ingredients and trends. Crucially, understanding the market and marketing aspects is very important, as product success depends not just on scientific formulation but also on market relevance and consumer appeal. While a strong scientific background is essential, being able to align formulations with market demands is key.
