Lemon is great in skincare because it helps to brighten (glow) lighten ( hyperpigmentation) and tighten the skin (fine lines and wrinkles). It is also a very valuable oil that provides hydration to the hair and scalp when applied topically. A few ah hah moments we discovered while conducting research is that lemon is highly affective in treating asthma; clearing out the nasal passage and sinuses. Lemon also is therapeutic as it helps expel gases from the body, relief an upset stomach as well as cramps. Who knew?
