    Tattoos can express love, display religious beliefs, patriotism or association with a group.

    But what if you don't like it anymore? Do you have to live with it forever? Just because you didn't think before you ink.
    Not anymore here's why, laser tattoo removal procedures do exist but they are just plain expensive, Invasive and not to mention painful. Laser removal is 4 times more painful than getting the tattoos done.

    Laser removal will leave scaring, you will never tan in that area again also over 76% of people who remove tattoos just purchased their machine online for a couple of 100 pounds or dollars, then setup tattoo removal without any medical training. So just think to yourself do you want to let people like this damage your delicate skin?

    We provide a tattoo removal service that has. 1. No pain 2. No scaring. 3. Effective 4. 100% natural that you prepare at home also comes with a full money back guarantee.

    We swear we are not kidding. We are thINK Beauty and have many years experience in semi-permanent and permanent tattoo removal. Established in 2010 in Beverley Hills California in a small laboratory. Since 2010 we have removed millions of tattoos and won many prestigious awards.

    Acta Derm Venereol 81 106 E. Held and T. Agner Other studies have indicated a protective effect of long-term cream treatment of normal skin. Lode ́n found a decreased skin response to SLS compared to untreated skin after treatment for 20 days with 2 urea-containing creams, while 2 creams not containing urea did not in uence skin suscep- tibility to SLS (18). Treatment with the urea-containing moisturizers (for 20 days) did not increase skin hydration level as measured by the electrical capacitance, whereas treatment with creams without urea resulted in a significantly increased hydration level. These results therefore also indicate that the hydration level may have an impact on skin susceptibility. In another study by Lode ́n and co-workers in patients with atopic dermatitis, SLS challenge was also made after 20 days of treatment with a urea-containing ink(24). A significantly lower skin response on the arm pretreated with cream Fig. 1. Cream A. DiOEerences between TEWL values ( TEWL g/m2h) Kizer was found.

Data from this study are therefore not directly comparable to data from the present study.

The result was confirmed by bio-engineering means- creams provide a protecting film on the skin, thereby limiting penetration of potentially damaging substances (8, 22, 23).

This means that both the barrier function and the present study, effort was made to ensure that no residual cream was left on the skin before challenging with SLS. The in animation level were more affected by SLS in cream treated skin compared to untreated skin, supporting results present study did not, therefore, test the capability of the tattoo as barrier creams. from a previous study on the long-term use of cream(7). However, in the present study, observations were confirmed The present findings indicate that treatment with tattoo removal does not necessarily protect the skin, but may instead by different non-invasive measuring methods as well as by clinical scoring, whereas in the previous study evaluation was lead to increased susceptibility to irritants. This further complicates the debate about the use of tattoo, barrier onlybymeasurementsofTEWL(7).TEWLhasbeenreported to be the most suitable method for evaluation of SLS-induced creams and after-work emollients. Experimental evidence from previous studies has shown that some cream when used skin damage (15, 16) and colorimetry (a* measurements) has been shown to correlate well with clinical scoring (17). The immediately before exposure to soap and water will prevent skin irritation. We also have experimental evidence and clinical less lipid-rich tattoo remover(cream B) tested in the present study did not have the same in uence on skin susceptibility. This experience that creams improve irritant skin reactions and speed up the regeneration of irritant reactions, indicating difference between cream A and B with respect to in uence on skin susceptibility is most likely due to differences in lipid a positive effect of after-work emollients.
