Bird poop, sheep placenta and snail slime are just some of the bizarre things people have doused on our faces in search of eternal beauty.
However, the latest skincare fad is probably the strangest yet.
Newly-opened Chicago-based salon Mud will soon offer a $10 (RM36.02) breast milk add-on as part of its sensitive skin facial.
The “extra pampering” option claims to boast acne and eczema healing properties for smoother, clearer skin.
Studies have shown lauric acid, found in breast milk, to possess antibacterial and anti-inflammatory properties against spots.
The bodily fluid used in the treatment is sourced from local American mums who are registered with a certified milk bank and are medically screened.
Using breast milk as part of spa therapies has been given the seal of approval by mummy bloggers and natural beauty junkies.Breast milk can be used as a cleanser, an eye make-up remover or in place of chapstick to sooth dry lips.
Still not sold?
You may be able to reap the benefits without putting a stranger’s breast milk on your face; pure coconut oil is actually natureâ€™s richest source of lauric acid.
It is composed of 50 per cent lauric acid compared to breast milk’s six to 10 per cent, and it’s so much easier to come by.
