Our take
Is Glycylglycine a Good Ingredient?
It's Fair because it functions mainly as a pH-buffering dipeptide, and evidence for direct skin benefits beyond that is limited. At higher levels it can shift product pH and may cause minor stinging in sensitive skin, which is what keeps the rating in the middle.
What it does
Skin Benefits
May help skin feel smoother and more comfortable by supporting a balanced environment; evidence for direct skin benefits is limited. Contributes to a more consistent feel in products used daily.

Before you use it

Typically low risk at cosmetic use levels, though mild, transient irritation can occur. No widely recognized topical regulatory restrictions.
