In atopic dermatitis, the two main physiophysiophysiologic abnormalities refer to the function of skin barrier and the regulation of skin immune responses. The likelihood of atopic cutaneous diathesis can be evaluated by a thorough analysis of the patient's history, as well as clinical and laboratory findings, resulting in the score of Erlangen Atopy (EAS). Objectives: To investigate the impacts of i) atopic skin diatesis according to EAS and (ii) the medical-assessed diagnosis diagnoses atopic 'dermatitis', 'allergic rhinitis' and 'allergic asthma' in the skin reactions of SLS. Methods: This is a retrospective data analysis of 2030 consecutive patch patients tested with SLS (0·25% acuous) of two tertiary remission centers in Germany, from 2008 to 2014. Results: Patients with a high probability of atopic skin diathesis did not show a significant increase in positive SLS reactions compared to patients without atopic skin diathesis (14·2% vs. 16·8%). The classification of positive skin reactions SLS (1-4) did not reveal differences in patients with or without atopic skin diathesis. In addition, diagnosis of atopic dermatitis, allergic rhinitis or allergic asthma had no impact on positive SLS skin reactions in multivariate logistical regression analysis. Conclusions: We do not find any association of greater skin irritability to SLS with atopic skin diathesis, atopic dermatitis, allergic rhinitis or allergic asthma in a cohort of large patients. Therefore, it seems that the skin irritability test with SLS, which is currently common practice in many centers, does not allow the prediction of susceptibility to irritating eczematous inflammation in atopic vs. nonatopic individuals. What do you know about this? The irritant contact dermatitis and atopic skin diathesis share the impaired skin barrier function as a physiological pattern. Sodium laurile sulfate (SLS) is tested at 0·25% aqueous as an irritating control in the patch test, and therefore the results could be affected by atopic skin diathesis. What does this study add? Faced with a long-standing paradigm, we do not find any association of greater reactivity to SLS patch tests in individuals with atopic skin diathesis, atopic dermatitis, allergic rhinitis or allergic asthma in a cohort of large patients. Therefore, irritating control tests with SLS, which is useful for interpreting the doubtful test results of allergen patch, does not depend on the state of individual atopia. © 2019 The authors.

But when it comes to irritation, the evidence is clear. So what are sulfates (or sulfates if you are reading in the US) and what makes them so bad for sensitive skin - and even not sensitive -? What is this? "Sulfate compounds are found in many personal care products such as shampoo, facial cleaners and body washers. They are also found in many domestic and industrial cleaning products," explains GP and skin specialist. "They work as surfactants, which means they can attract water and help decomposition of oil and rubble, therefore helping the cleaning process. The main sulphates used in skin care are sodium lauril sulfate (SLS), sodium dodecyl sulfate and sodium laurete sulfate (SLES). "The case against SLSNot all surfactants (which are agents used in detergents) are bad - in fact, far from it, as they are quite necessary for effective cleaning. But SLS is the one you've probably heard of, and for good reason. In 2013 the Regulatory Agency for Medicines and Health (MHRA) issued an aqueous cream, a product recommended by doctors for eczema, warning that if used as a license moisturizer could cause skin irritation and skin thinning, with SLS considered the probable culprit. In one study, those who used aqueous cream twice a day found that the treated areas were 12% thinner, with an average increase of 20% in water loss compared to untreated skin. Popular cream is now recommended only for use as a soap substitute. Meanwhile, the irritating properties of SLS are so safe that it is used as a marker in scientific studies when testing the safety of other ingredients; to establish how irritating it is to the skin, its effects are compared to that of SLS. SLS irritating properties are so safe that it is used as a marker in scientific studies by testing the safety of other ingredients It does not stop there either; while a reaction or irritation could initially occur, the long-term effects are equally worrying, as the founder and organic expert of Content Beauty tells me. "The main reason I recommend avoiding SLS in particular is the increased permeability of the skin with which it stays. Several tests have shown that the absorption of other chemicals present in skin care, including polyethylene glycol, is increased when SLS has been used before or is part of the formulation. So if you are prone to sensitivities, irritation can increase as the skin barrier, which is there to protect you from irritation, is compromised. "Why should you avoid it? Dr. Sturnham suggests that the potential symptoms of a SLS problem are redness, sensitivity, dryness, braking, or a 'tight' feeling; most of the products that contain sulphate foam, and your skin will probably feel clean afterwards - but do you really want your skin to feel like your dishes? That narrow, 'clean' feeling is the result that their natural oils deviate, their skin dry and their barrier of all that is important is deteriorating. More importantly, if you suffer with any other skin condition you may be making things worse. "We have evidence that sulphates can cause skin irritation and I often find foam cleaners to be highly aggravating for my patients with , and other inflammatory skin conditions," explains Dr. Sturnham. "I usually advise my patients to stay away from foam cleaners, to avoid any possible drying or irritating effect. "That's also for SLES. "Some studies have suggested that SLES is safer to use than SLS, however, both have a potential irritating effect, so my advice is to avoid all sulfates if possible," says Dr. Sturnham. Imelda agrees that no one is worth the risk: "Switching to one of the alternatives, sodium laureth sulfate does not solve the problem. Although it is considered less harsh on the skin, it crosses a process called ethoxylate that has concerns about contamination with 1-4 dioxan, a known carcinogen linked to organ toxicity. " Worryingly, not only skin care products you need to be aware of - you need to check your shampoo and toothpaste labels as well. If you regularly suffer from oral ulcers, your toothpaste and your foam action may be the fault, as the dentist explains: "Some commonly used oral care ingredients can cause irritation and abrasions inside the mouth, which can cause mouth ulcers and gum problems; a research study has shown ulcers without SLS reduced in prone individuals by 80%. If you have recurring canker ulcers or mouth ulcers, you would recommend avoiding ingredients such as sodium laurile sulfate and alcohol. "In the meantime, there has been a sudden burst of hair care products throwing (or perhaps simply redesigning their packaging) with their sulphate-free credentials. Ideal for those with sensitive skin and scalp, the trend is most likely to the popularity of the hair coloring and semi-permanent straightening treatments like the dry Brazilian coup, which the hairdressers advise will last longer if you avoid the foaming and stripping qualities of SLS in your shampoo. What to use instead So you want to get away from SLS - but what is the alternative? Fret no - you don't need to give up fresh breath, clean hair and clean skin. It will only take a little salvvy shopping, something that will be more than used if you are sensitive. As with the example of aqueous cream, SLS is less likely to cause much damage when the skin was washed immediately - but why use an irritant on your skin at all? Dr. Sturnham recommends using unparalleled cleaners, without sulfate, without foam. "Look for soft cream or gel cleaners, rich in natural phytonutrients as cleaning ingredients, such as fruit extracts and mixtures of natural oil. I love wheat and rosehip cleaners, rich in identical lipids of the skin - gently clean the skin, without stripping it of their important oils. "The formula of your chosen product can help to counter any effect of surfactant drying, also, as Imelda explains. "If it is sensitive, it would avoid foam products and look at the soap bars or liquid soap that contain the glycerin derived from plants." Hyaluronic acid is another moisture-enriching ingredient that is worth looking for, also - more moisture, better. Fortunately, there are a lot of products that are free of SLS - and they will usually scream about it, too (although it always helps ). Some brands have specific 'sensitive' or 'free-of' ranges within their product offering, while other brands make a statement and avoid it completely; meanwhile, any organic product certified by the Association of Soils will definitely be sulfate free. Here is a list (without finite means) to start - because confirmed irritants do not take place in their bathroom shelf. For your skin: Skincere - a free range of range, recommended by Dr SturnhamPai - one of my most reliable organic beauty brands, also recommended by Dr. Sturnham and specifically made for sensitive skinChild's Farm - a great range of SLS free for children and sensitive skinsREN - a fragrance brand that is free of sulfate between a great list of other irritants - try the Evercalm cream rangeCetraben - an alternative UltraDEX Low-Abrasion Toothpaste - SLS-free, alcohol-free, and even gluten-free Let me know in the comments or tweet Join the conversation Like what you see?
