Is Polyglyceryl-3 Diisostearate Acne Safe?

It gives your foundation that "flawless, glowing finish," but for acne-prone skin, it is a silent nightmare. Here is why Polyglyceryl-3 Diisostearate might be destroying your skin barrier.

What is Polyglyceryl-3 Diisostearate?

Polyglyceryl-3 Diisostearate is a synthetic oil and emollient that gives products a slick, sheer feel. It is highly comedogenic, meaning it penetrates deep into the pores. Brands love it because it reduces the "greasy" feel of lotions and makes liquid foundations spread effortlessly.

You will find it hiding in countless mineral powders, "clean" foundations, and high-end blushes. But this synthetic shimmer comes at a devastating cost for sensitive and acne-prone biology.

Why It Ruins Your Skin Barrier

1

Microscopic Needle Structure

On a molecular level, Polyglyceryl-3 Diisostearate is small enough to penetrate the stratum corneum but sticky enough to bind with dead skin cells and sebum. This creates a solid plug deep within the pore, inevitably leading to closed comedones and cystic acne.

2

Cystic Acne Trigger

Because it is uniquely heavy and adheres so strongly to the skin, it sinks deep into pores. Sweat and sebum mix with the heavy crystals, creating an impenetrable plug that erupts into painful, deep cystic acne.

3

Severe Itching & Irritation

Many people report suddenly developing hundreds of tiny, flesh-colored bumps (closed comedones) on their forehead and cheeks. This is the hallmark signature of Polyglyceryl-3 Diisostearate congesting the follicles.

Stop Guessing. Start Scanning.

Sephora reviews won't tell you if a product contains Polyglyceryl-3 Diisostearate. REMAKE does. Scan any barcode to instantly expose toxic, pore-clogging ingredients hidden in the fine print.
