Unlike flat 2D cultures, skin-on-chip for cosmetic testing in the body can mimic how blood and fluids flow through skin tissue. This makes it easier to track how ingredients interact with the skin over time. For example, it can help identify how a product may affect skin aging or how fast certain ingredients get absorbed.

The idea is simple: a microfluidic chip for cosmetic testing moves small amounts of liquid (like blood or product samples) through tiny channels, like fluids moving through our body. Skin tissues or models can be placed inside the chip to test how they react to different ingredients. What's clever about this setup is that it keeps the tissues active for longer, and the results closely match how human skin would behave in real life.

Traditional techniques for diagnosing skin conditions often rely on visual inspection and patient history. While these are critical, we don’t always provide the whole photo. Skin imaging technology enables dermatologists to visualize deeper layers of the skin, facilitating the detection of early symptoms of damage, disorder, or aging.
