Pumpkin enzymes in peels: what they do and what they do not

Pumpkin turns up in Korean skincare more and more, usually presented as a natural alternative to acids. In fact it works alongside them rather than instead of them, and that is worth knowing before you buy.

Pumpkin on a Korean label usually means an enzyme peel. The phrase natural enzymes instead of acids sounds convincing and sells well. But it is imprecise, and a buyer should know exactly where.

What pumpkin genuinely brings

Three things at once. Proteolytic enzymes that break the protein bonds between dead cells. Vitamins and minerals — pumpkin is rich in both, and in a peel that works as simultaneous nourishment. And mildness: an enzyme acts on the surface and does not shift the skin's pH the way an acid does.

That is why an enzyme peel is usually better tolerated and suits people for whom an acid peel does not.

How an enzyme differs from an acid

An enzyme takes apart the bonds between cells. An acid works differently: AHA loosens cohesion in the upper layers, BHA gets into pores because it dissolves in oil.

So they do different jobs. An enzyme removes surface roughness well and leaves pores alone. An acid goes deeper and works on sebum plugs.

This is why serious formulations put them together rather than choosing one. When a manufacturer writes enzymes plus AHA and BHA, that is not marketing clutter but a division of labour.

What a high extract percentage means

Wording such as seventy-five per cent pumpkin extract refers to the share of the water phase replaced by extract, not to the concentration of an active compound.

It is an honest and useful figure, but it says nothing about enzyme activity. Enzyme activity is measured separately and stated in units, not as a percentage of raw material.

If what matters to you is the peel's performance, ask for enzyme activity rather than extract percentage.

What to ask the manufacturer

Enzyme activity and the method by which it was measured.

What else sits alongside in the formula: acids, and if so which ones and at what share.

The physical form. A powder means the enzyme activates on mixing and is stable until then; a ready paste is more convenient but requires more careful stabilisation.

And the usage protocol: the same formula can be sold as a weekly home step or as a treatment-room procedure, and that changes how it is presented on the shelf.
