Hubby has been faithfully using the Helichrysum essential oil for about a month and his arms look so much better! The skin is now smooth and soft and when he does bump his arm and gets a bruise, the healing time is so much quicker. I use fractionated coconut oil as the carrier and here's the formula that was taken from their website:

"A common ratio for diluting Helichrysum essential oil in fractionated coconut oil is a 2-3% dilution, according to Nomad Botanicals. This means you would use 2-3 drops of Helichrysum essential oil for every teaspoon of fractionated coconut oil, or 12-18 drops per ounce of carrier oil, according to Eden Botanicals.

1% Dilution:
For sensitive skin or when starting, you can use a 1% dilution, which is about 6 drops per ounce of carrier oil, says Wyndmere Naturals.
2-3% Dilution:
This is a general guideline for most adults and is a safe and effective dilution for topical application."
