It looks like you follow a more natural approach so I'll just throw this out there: calendula oil.
"Calendula is traditionally used for its anti-inflammatory, anti-bacterial, anti-fungal, and healing properties. Calendula Infused Oil is traditionally used for skin irritation due to chafing, wind, cold or dry air exposure, to help heal dry, cracked or itchy skin, cuts, infected and inflamed wounds, hard-to-heal sores, to decrease the inflammation of sprains, stings, and other swellings, soothes skin irritations, stimulates wound healing, and soothes pain. Calendula oil is often used to aid in lessening scarring after wounds heal and after stitches are removed."
It's found in popular scar and stretch mark salves/oil like Bio-Oil. |
