One bar. Every hidden spot.

Dark patches love the places nobody sees: where skin folds, rubs and sweats. Asshine goes there, so you can stop hiding them.

01Main character

Booty

The reason we exist. Lather up both cheeks and let it work on the dark patches nobody talks about.

02

Inner thighs

Thigh rub leaves its mark. Asshine helps fade the look of it, one shower at a time.

03

Underarms

Shaving shadows and dark patches? Sleeveless season is back on.

04

Elbows & knees

Rough, dark joints get a brighter, more even look.

05

Neck

For the darker ring you keep hiding under collars and hair.

06

Knuckles

Hands that look as good as your nails do.

Three steps. Zero shame.

  1. A hand rubbing the orange Asshine bar over an elbow, building a rich lather

    Lather up

    Wet the area and work Asshine into a rich lather with your hands.

  2. White lather resting on an elbow while it works

    Let it sit

    Leave the lather on for 2–3 minutes so the kojic acid can do its job.

  3. Two panels: water rinsing the lather off an elbow, then moisturiser being rubbed in

    Rinse & moisturise

    Rinse with lukewarm water, pat dry and follow with a fragrance-free moisturiser.

  • Use it every day
  • Patch test 24 h first
  • SPF on exposed spots like neck & elbows
  • Skip broken or irritated skin

What's inside

Born from sake. Made for booty.

Kojic acid comes from koji, the same fungus used to ferment sake and soy sauce. On skin, it slows down tyrosinase, the enzyme behind melanin, which helps dark spots look lighter over time.

Asked & answered.

Still curious? Slide into our DMs at @asshine.au.

Can I use it on my butt crack?

On the outside skin, yes: cheeks, crease and bikini line. Keep it away from mucous membranes and anywhere inside, and stop if it stings or burns.

How fast will I see results?

Dark spots take time to fade, so consistency is everything. Plan on several weeks of regular use.

Will it tingle?

A light tingle can happen with kojic acid. Redness, burning or peeling means stop and give your skin a break. Always patch test first.

Is it for everyone?

Check with your doctor first if you're pregnant, breastfeeding or have very sensitive skin. A dark patch that feels velvety, keeps spreading or showed up suddenly is worth showing a doctor.

Shipping & returns?

Shipping is free on every order, always. Orders ship the same or next business day. Returns are covered in our refund policy.
