💎 Whoever said diamonds are a girl’s best friend hasn’t talked to a working, busy dermatologist💎
Cryotherapy aka liquid nitrogen is a handy tool for my job. A day doesn’t go by where I’m not searching for this little tool!
🥶 What is cryotherapy?
❄️ refers in the derm world to liquid nitrogen used for cryosurgery
❄️liquid nitrogen is extremely cold (-320 degrees Fahrenheit!)
🥶 What does it do?
❄️ used for it’s extremely low temperature to destroy tissue and skin
❄️when lesions are frozen, ice crystals start to form between cells. This creates an osmotic gradient and pulls water out of the cell. When the crystals outside of the cell thaw, water rushes back into the cell and causes the cell to burst and die.
❄️ freezing also leads to ischemia, causing lack of nutrients and blood vessel supply to the tissue ⠀⠀⠀⠀⠀⠀⠀⠀⠀
🥶 What do derms use it for?
❄️ Pre-cancers: also known as actinic keratoses, cryotherapy destroys pre-cancerous cells, thus preventing transformation into squamous cell carcinoma
❄️ Skin tags
❄️ Seborrheic keratosis: also known as wisdom spots, these benign wart like lesions appear as we get older and can occasionally become symptomatic
❄️Solar lentigo: also known as sun spots
🥶What to expect after cryotherapy?
❄️ The process takes several days. The lesion frozen will become red and possibly form a blister. Over time, the lesion will eventually fall off
❄️ Thicker lesions may require several treatments prior to resolving
❄️ Side effects include pain, burning, blister formation, possible infection and possible lightening of the skin especially in those with darker skin types ⠀⠀⠀⠀⠀⠀⠀⠀⠀
Be sure to see your board certified derm to discuss if this is the right treatment for you!
