Skin chip refers to two distinct concepts:
1. Skin-on-a-Chip Technology in Scientific Research
Scientists are developing innovative microfluidic devices, often called "skin-on-a-chip," that mimic the structure and function of human skin. These chips contain different types of skin cells (like keratinocytes and fibroblasts), and sometimes even vascular structures, grown in a controlled environment. The purpose is to:
- Test drug responses: Predict how the skin will react to various substances, such as new drugs or cosmetics. This reduces the need for extensive animal testing and provides more accurate human-relevant data.
- Study skin diseases: Model skin conditions and disease processes in vitro (in a lab setting) for better understanding and treatment development.
- Improve cosmetic products: Evaluate the effectiveness and safety of cosmetic products before they reach the market.
Examples of this technology include:
- A novel skin-on-a-chip device with an innovative microfluidic design for maintaining normal skin tissue for extended periods. [Source: Design and evaluation of a skin-on-a-chip pumpless microfluidic ...]
- A microfluidic skin chip incorporating vasculature to replicate immune responses in the skin. [Source: Microfluidic skin chip with vasculature for recapitulating the immune ...]
2. Edible Crispy Skin Chips from Various Sources
"Skin chips" also refer to a variety of crispy snacks made from the skin of different foods, including:
- Potato skin chips: Made by peeling potatoes, preparing the skins (e.g., soaking, drying, seasoning), and then baking or frying them until crispy.

- Sweet potato skin chips: A similar process to potato skin chips, but using sweet potato skins. [Source: Salty Sweet Potato Skin Chips | Half Baked Harvest]
- Chicken skin chips: Crispy chips made from chicken skin, often baked or air-fried. These are popular low-carb or keto-friendly snacks. [Sources: Crispy Chicken Skin Chips (Air Fryer or Oven) - Nom Nom Paleo®, Keto Crispy Chicken Skin Chips (Oven or Air Fryer)]
The preparation methods vary, but generally involve:
- Cleaning and preparing the skins.
- Seasoning with oil and spices.
- Cooking until crispy, often using an oven or air fryer.
