The Science Behind It

Plain acid sticks were made for rough skin and bumpy arms (KP). That's a different kind of texture from SK buildup.

SK buildup is thicker and crustier, so it needs softening before acids can reach it. That's why Arcor leads with 5% urea, and balances the formula with 10% shea butter for thinner skin.

Frequently Asked Questions

How long until I see a difference?

Most people notice skin feels softer early on. Flatter-looking spots take consistent use over several weeks, and raised ones take longer.

Will it stop new ones from appearing?

No, and nothing topical can. It helps you keep pace, so the ones you have look flatter and smoother, and new ones are easier to stay on top of.

Is it gentle enough for sensitive skin?

It's balanced with 10% shea butter and urea. Start every other day and patch test if your skin is reactive.

Arcor SK Body Stick

$42.00

Why one-spot-at-a-time never catches up

SKs are built from hardened, crusty keratin that keeps building across the whole area. Freezing handles a few at a time, and more keep coming. Most creams and acid sticks just sit on top of the crust and never get through.

  • Freezing

    One spot at a time, the visits add up, and it can leave white marks.

  • Spot creams and acid sticks

    Sit on top of the crust.

  • Home remedies

    ACV, wart remover and freeze kits work on one spot, and you have dozens.

How it works: Soften → Smooth → Stay on

  1. Soften

    5% urea softens the hard, crusty buildup so the actives can get in.

  2. Smooth

    7% glycolic acid works from the outside in; 1% salicylic acid works from the inside out.

  3. Stay on

    Leave-on, not rinse-off. One swipe covers every spot at once.

Frequently asked questions

What are SKs, and is this made for them?

Will it stop new ones from appearing?

No, and nothing topical can. It helps you keep pace, so the ones you have look flatter and smoother, and new ones are easier to stay on top of.

How long until I see a difference?

Most people notice skin feels softer early on. Flatter-looking spots take consistent use over several weeks, and raised ones take longer.

Is it gentle enough for sensitive skin?

It's balanced with 10% shea butter and urea. Start every other day and patch test if your skin is reactive.

Can I use it on my face?

Yes. It's formulated for the body and can also be used on the face. Patch test first and keep it away from the eye area.

How do I reach my back?

Use the Lotion Applicator included in the bundle.

How long does one stick last?

Up to 4 weeks, depending on how much area you cover.
