Serum z witaminą C 15% Deliplus Anti Ox

The barcode 8402001037979 corresponds to a product labeled "Serum z witaminą C 15% Deliplus Anti Ox" (Vitamin C 15% Serum by Deliplus Anti Ox). Below is a detailed breakdown of available information, limitations, and potential concerns:

Product Overview

• Type: Topical skincare serum (likely a vitamin C serum).
• Key Ingredient: 15% L-ascorbic acid (vitamin C), a potent antioxidant used for brightening skin, reducing hyperpigmentation, and boosting collagen production.
• Brand: Deliplus (a Polish skincare brand known for affordable, vitamin C-based products).
• Formulation: Typically a water-based serum with pH-balanced L-ascorbic acid (though exact formulation details are not publicly available for this specific barcode).

Potential Warnings & Concerns

1. Skin Sensitivity:

   • High concentration (15%): While effective, L-ascorbic acid at this level can cause irritation (redness, stinging, or dryness) for sensitive skin, especially if used undiluted or over-applied. Patch-testing is recommended.
   • pH matters: Vitamin C serums must be pH-balanced (typically ~3.5–3.8) to avoid degradation or irritation. Poor pH stability could reduce efficacy or harm skin.

2. Stability Issues:

   • L-ascorbic acid oxidizes when exposed to air/light, losing potency. The product may degrade faster if stored improperly (e.g., in a non-airtight container or without UV protection).
