In plain English

This ingredient is a type of ester, which is a fancy name for a molecule made from an alcohol and a fatty acid. In skincare, it acts as an emollient, meaning it fills in the tiny gaps between skin cells to make your skin feel smoother and softer. It also helps other ingredients spread more evenly and gives products a silky, non-greasy feel.

What it is

Diglyceryl Sebacate/Isopalmitate is a semi-synthetic ester formed by combining diglycerin with sebacic acid and isopalmitic acid. It is designed to mimic the skin's natural lipids, making it a gentle and effective moisturizing ingredient.

How it works

It works by forming a thin, breathable film on the skin's surface that reduces water loss (transepidermal water loss, or TEWL) and improves skin barrier function. Its molecular structure allows it to absorb quickly without leaving a heavy or sticky residue.

Pros

Lightweight feel

Absorbs quickly without greasiness, making it ideal for daytime use and for those who dislike heavy creams.

Low irritation potential

Its gentle nature makes it suitable for sensitive or reactive skin, reducing the chance of redness or breakouts.

Cons and cautions

Limited hydration for very dry skin

While it softens the skin, it may not provide enough moisture for severely dry or compromised skin barriers.

Less research available

Compared to more common emollients like glycerin or shea butter, there is less published research on this specific ester.

Best for

  • People with normal to oily skin looking for a lightweight moisturizer
  • Those with sensitive skin who need a gentle, non-irritating emollient

Use caution if

  • Individuals with very dry or dehydrated skin may need a richer emollient

Usage tips

Look for this ingredient in lightweight lotions or gel-creams for a matte finish.
Layer with a humectant serum (like hyaluronic acid) for added hydration.
