According to this site, which discusses the safety of diluting citrus essential oils in carrier oil for application on skin, it's considered safe to use 24 drops of grapefruit oil in 30ml of carrier oil, for lemon it's 12 drops, for lime 4 drops, and for (cold-pressed) bergamot essential oil only 1 drop is safe.
