AMOREPACIFIC Refining Powder-To-Foam Cleanser Versus White Ichigo Powder Tech-Wash

Because hydrolyzed hyaluronic acid is smaller in size, it can slip past your outermost layer of skin more easily than full-sized HA.

Most formulations will combine all sizes to get the best of both worlds.

Typical usage levels range from 0.01-1%. Any percentage higher than 2% might become goopy and tacky.

In skincare, proteases act as biological catalysts that mimic this natural desquamation process. You can think of it as giving your skin's own renewal system a nudge.

By breaking down the bonds that hold dead skin cells together, proteases help accelerate cell turnover to:

One reason they're becoming a popular AHA alternative is because proteases are considered effective while also being well-tolerated on skin. Because they work at a protein level rather than by lowering the skin pH, they can be a good option for those sensitive to AHAs.

Available in vitro and in vivo studies show positive exfoliant results but clinical (human) trials specifically on enzymatic exfoliation are still limited at this time.

Just one thing worth noting: temperature, pH, and stabilization are important factors that affect enzyme activity. The formulation quality definitely matters with this ingredient.

This ingredient can be either microbial sourced or plant-derived (papain from papaya, bromelain from pineapple).

The unique structure of silica enhances the spreadability and adds smoothness, making it a great texture enhancer.

It is also used as an active carrier, emulsifier, and mattifier due to its ability to absorb excess oil.

In some products, tiny microneedles called spicules are made from silica or hydrolyzed sponge. When you rub them in, they lightly polish away dead skin layers and enhance the penetration of active ingredients.

This ingredient also helps improve the spreadability of a product.

This ingredient hasn’t been shown in studies to feed fungal acne yeast.

Interestingly, the size of the molecule affects its behavior:

Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair.

Many serums use a blend of both weights so you can get surface hydration plus longer-lasting and deeper effects.

You'll typically see concentrations between 0.1-2% for this ingredient.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!

Cornstarch is a common food ingredient used to thicken soups or to make corn syrup.
