Glycerin

Glycerin (グリセリン) is the Quirk used by Mitsuki Bakugo.

Description
The Quirk allows the user to produce a smooth liquid from their skin.

Its moisturizing effect gives Mitsuki a flawless skin quality which maintains her youthful appearance, despite her age.

When genetically combined with her husband's Quirk, it results in an Explosion Quirk, which is used by their son.
