Retinal (Retinaldehyde) Powder Changed Color and Texture Upon Arrival
Question
Based on the product description for Retinal (Retinaldehyde), which states it is a yellow-orange powder that degrades quickly when exposed to UV light:
Why did the product I received arrive as a dark brown color (like tamarind paste) and very sticky, not a powder?
Has it degraded, or can it still be used?
Answer
Based on your description, the change in color from yellow-orange powder to dark brown and sticky is a strong indication that the Retinal (Retinaldehyde) product you received has degraded.
Retinal is highly sensitive to light, air, and heat, and it degrades relatively quickly, especially when exposed to UV light as mentioned on the product page. The change in color and texture you observed are typical signs of oxidation and degradation.
A degraded product may have lost its effectiveness and could potentially contain breakdown products. Therefore, it is likely that the product is no longer in its intended quality and may not provide the desired benefits. It is generally advised not to use skincare ingredients that show clear signs of degradation like this.
You should contact myskinrecipes.com regarding the issue and provide them with details about the condition of the product you received.
