Glycerin
Is Glycerin safe for seborrheic dermatitis?
Glycerin is generally a reasonable ingredient to consider when you have seborrheic dermatitis, especially if your skin also feels dry. It helps the outer skin layer hold onto water, which makes it useful in a gentle moisturising routine.
That moisture support does not make glycerin a treatment for seb derm itself. The finished product still matters: fragrance and other ingredients may affect how comfortable it feels on your skin. A fragrance-free moisturiser is a sensible place to start, and you can judge the whole formula and your own response from there.

What is Glycerin used for in skincare?
Glycerin, also called glycerol, is a humectant: it attracts water and helps the outer layer of skin retain it. That is why it appears in moisturisers such as creams and lotions. It can also help a product retain moisture and dissolve other ingredients. Glycerin supplies the water-binding part of a formula; other ingredients may add softness or help slow moisture loss. Its presence tells you the intended role, while the complete formula determines how the product feels and performs.
