Sensitivity
Skin irritation is one of the most significant concerns when it comes to cosmetic products. With the skin being constantly exposed to a variety of external and internal stressors, ensuring that cosmetic products are safe and non-irritating is crucial. Skin irritation occurs when a product causes a negative reaction on the skin, typically resulting in redness, swelling, itching, or burning sensations. These reactions can be caused by various factors, including harsh chemicals, fragrances, preservatives, or other ingredients in cosmetic formulations. For cosmetic products, skin irritation can result in adverse reactions for consumers, especially those with sensitive skin.

Biomarker Testing List:
| Biomarker | Remarks on the Biomarker |
|---|---|
| Oxidative Stress Marker (Malondialdehyde [MDA]) | Oxidative stress worsens acne; lower levels show antioxidant activity, reducing inflammation. |
| Sebum Production | Excessive sebum contributes to acne; reduction in sebum levels helps reduce clogged pores. |
| Matrix Metalloproteinase (MMP-9) | Degrades skin tissue in inflamed areas; lower MMP-9 levels prevent acne scarring. |
| Inflammatory Cytokine (Interleukin-8 [IL-8]) | Attracts immune cells to infection sites; reduced IL-8 levels indicate reduced inflammatory response. |
| Cutibacterium acnes | Acne-causing bacteria; decreased bacterial load shows antibacterial effectiveness of the product. |
| Pro-inflammatory Cytokine Interleukin-1 alpha (IL-1a) | Inflammatory cytokine elevated in acne; reduction indicates anti-inflammatory effects on the skin. |
| Skin pH | An altered pH encourages bacterial growth; balanced skin pH supports healthier, acne-free skin. |
| Transforming Growth Factor beta1 | Promotes scar formation; reduced TGF-β1 helps in healing acne without scarring. |
| Keratin 5 | Keratin 5 is a structural protein found in the basal cells of the epidermis, playing a crucial role in maintaining the integrity and strength of the skin, particularly in areas subject to mechanical stress. |
| Keratin 14 | crucial for maintaining skin cell integrity and providing mechanical strength to the skin, particularly in the epidermal cells of the skin and mucous membranes. |
| Propionibacterium acnes | This bacteria contributes to acne inflammation; a lower count indicates reduced bacterial activity. |
| Sebum Production | Sebum production refers to the secretion of oily substances by sebaceous glands, which helps lubricate and protect the skin but can contribute to acne when overproduced. |
| Leukocytic Pyrogen Pro-Inflammatory Cytokine Interleukin-1 beta (IL-1b) | Interleukin-1 beta (IL-1β) is a pro-inflammatory cytokine that acts as a leukocytic pyrogen, triggering fever and promoting inflammation during immune responses. |
| Sebum Production Levels | Excessive sebum contributes to acne; reduction indicates better oil balance and fewer breakouts. |
| Propionibacterium acnes (P. acnes) Count | This bacteria contributes to acne inflammation; a lower count indicates reduced bacterial activity. |
| Inflammatory Cytokine (Interleukin-1 [IL-1]) | Elevated levels indicate skin inflammation; reduction reflects improved skin health and reduced acne. |
| Inflammatory Cytokine (Interleukin-8 [IL-8]) | A pro-inflammatory cytokine that plays a pivotal role in immune response, fever induction, and the activation of other inflammatory mediators. |
| A pro-inflammatory cytokine that attracts and activates neutrophils, contributing to inflammation and immune defense. | |
| Keratinocyte Hyperproliferation Markers | Increased keratinocyte activity can lead to clogged pores; lower levels suggest reduced pore blockage. |
