Lines around the upper lip are most commonly caused by repeated facial expressions like smiling, laughing and talking, and they are quite common in both men and women as they age. However, these lines can age you prematurely. Natural home remedies can help to smooth upper lip lines by tightening and firming the skin, says Marcel Lavabre, author of "Aromatherapy Workbook.”

Combine 1/2 teaspoon Clary sage essential oil, 1/2 teaspoon frankincense essential oil, 1/2 teaspoon patchouli essential oil, 1/4 teaspoon myrrh essential oil, 1/4 teaspoon carrot seed essential oil and 1/2 cup jojoba oil in a small bottle with a tight-fitting lid.

Cover the bottle and shake vigorously for 20 seconds to combine the contents inside.

Pour a small amount of the essential oil mixture onto a clean cotton pad. Let the oil soak into the cotton for one minute.

Rub the cotton pad on the upper lip area. Make sure not to get the mixture in your mouth or on your lips to avoid irritation.

Leave the oil mixture on your skin for 35 or 40 minutes, or until the oil is almost completely dry.

Rinse your skin with cool, clean water. Wash with a mild facial soap and apply your regular facial moisturizer.

Repeat this treatment daily, once in the morning and once in the evening. Discontinue use if the mixture causes redness or any other type of irritation because this could be an allergic reaction.

Keep unused portions of this mixture in the refrigerator or in a cool, dark and dry place for 60 days. Discard the mixture after 60 days.
