Comments on: Can I Apply Eyeliner on the Inside of My Eye Lid? http://thebeautybrains.com/2006/06/24/beauty-q-a-can-i-apply-eyeliner-on-the-inside-of-my-eye-lid/ Cosmetic chemists answer your beauty product questions! We are a group of cosmetic scientists who understand what the chemicals used in cosmetics really do, how products are tested, and what all the advertising means.

Finally a true answer to this question. My aunt after many years of applying liner to her inner rim became legally blind. Doctors say this is one of the main contributing factors to her eventual vision loss. As a makeup artist since 1999 I have encouraged clients to not do this. But, because their friends say they do it they think its ok. There should be a beauty public announcement that says. "Friends don't let friends answer beauty questions." So glad I found this.

Jeez Angela,

You must have used a lot of eyeliner!

I did this for a short while, perhaps a few months at the most. Later on, I had sinus surgery to put in sinus windows...the doctor scraped a lot of mystery "gunk" from the sinuses behind my cheeks...it was blue, and was actually the eyeliner I had been using...a bunch of old eye liner went into my tear duct and into my sinuses. This cannot be good! Do not do this. I did this for a short while, perhaps a few months at the most.

The history and scientific studies so far done, indicate that the major constituent of Kohl is Galena, i.e., lead sulphide an inorganic form lead which is practically insoluble in aqueous (water) phase. I have gone through a number of such studies where Kohl is applied to both animal (rabbits) and human eyes regularly for about three months, but no difference in blood lead level was noted between pre and post application of Kohl. Confirming that lead present in Kohl can not be absorbed through transcorneal route. So there is no question of lead poisoning with the application of Kohl (Surma). Out of several reference, I would like to quote one reference here under the heading of ” Features of Poisoning” The sub-headings 5.1.4 Ocular (Inorganic Lead) Authors, Grainne Cullen, Alison Dines & Stoyko Kolev ” Lead sulphide (from the eye cosmetic surma) has caused minute conjunctival abrasions but no toxic injury to the eye ” - Statement released by the National Poisons Information Services (London Centre), Medical Toxicology Unit, Guy’s & St Thomas Hospital Trust, London - Monograph For UKPID - Lead (UK PID) page # 15 (March 1996). In my opinion, even the minute conjuntival abrasion is not possible, if good quality Kohl (Surma) is used. Further, the dose which is applied into the eyes at one time is also very small and if quantified, it will be in microgram, irrespective of the high content of Galena (Lead sulphide) present in the whole container. I would urge here not to link the misuse Kohl (Surma) with it’s toxicity cause. Even misuse of water can lead to death. Thus based on this we can not stop using or storing water in our house. Scientifically, I would classify the action and properties of Kohl into three different directions or categories: 1. Adsorptive - which is surface phenomena. Thus helps in cleaning the eyes from dust as well as other foreign matters invading the eyes. 2. Astringent - which is observed at the site of its application. Since Galena (Lead sulphide and the main constituent of Kohl) has an affinity for sulphur, therefore it combines with sulph-hydryl groups of the membrane and produces a local action due precipitation of proteins in a very low concentration. 3. Anti-infective - this property is due to the coagulation of specific inhibitory action of Galena with vital enzyme system of the cell. this phenomena is known as Oligodynamic Action. Despite all these facts, however, surprisingly it has been stated by certain school of thoughts due to unknown reasons that Kohl (Surma) is or might be injurious to health due to the absorption of lead from eyes. I have incorporated enough matter on the subject which can help a common man & women to understand the situation. Kohl (Surma) does not absorb through transcorneal route as it is practically insoluble in aqueous medium of the eye. Further, the alkaline nature of lachrymal restricts it’s dissociation and the positive intra-occular pressure further prevents the absorption or penitration.
