Disclaimer
SOURCE LAB develops cosmetic care products for skin, hair and body. On this page, we explain transparently how our product descriptions, references to skin needs and scientific information about individual ingredients should be understood.
Cosmetic care is not medical treatment – and a study on an individual ingredient is not automatically evidence of efficacy for a finished product.
Cosmetic claims, skin needs and scientific research clearly separated.
When we describe a cosmetic effect of a SOURCE LAB product, that statement refers to the respective finished formulation and must be supported by the evidence available for that claim. When we discuss individual minerals or ingredients from a scientific perspective, that information refers exclusively to the cited publication and its specific study conditions.
Our products are cosmetic products. They are not intended to diagnose, treat, cure or prevent diseases.
Dryness, tightness, visible flaking, blemishes or skin that appears easily irritated describe skincare needs and observable skin conditions.
Product-related efficacy claims are statements about the finished cosmetic product – not claims that every individual ingredient produces the same effect on its own.
Results relating to individual minerals, salts or test solutions initially apply only to the substance, concentration, formulation, application and study population actually investigated.
Information about our cosmetic products
The products offered on the-source-lab.com are cosmetic products for external use. They are intended for cleansing and caring for the skin and hair, for protecting and maintaining a well-cared-for skin condition and – in the case of our deodorants – for cosmetic odour control.
They are not medicinal products or medical devices and are not intended to diagnose, treat, cure or prevent diseases. The content on this website does not replace medical advice, diagnosis or treatment.
Terms such as dry, sensitive, delicate, irritated-looking, blemish-prone or spot-prone skin, as well as references to tightness, roughness, visible flaking, burning, stinging, shine or comparable sensations and skin conditions, are used in a cosmetic context. They do not constitute a medical diagnosis. In particular, references to spots or blemishes do not refer to the treatment of acne as a medical condition.
A specific skin concern describes why someone may want skincare. It is not a promise to treat a disease or the medical cause of that symptom.
What our skincare effect claims mean
When we attribute a specific cosmetic skincare effect to a SOURCE LAB product, that statement – unless explicitly stated otherwise – refers to the finished formulation as a whole. It should not be understood to mean that every ingredient contained in the product produces that effect on its own or that a single ingredient study automatically proves the effect of the finished product.
Conversely, we clearly identify scientific information about individual minerals or ingredients as such. This information is intended to make our ingredient choices and the scientific context of certain components transparent. Findings from such research may only be transferred to a finished product where that transfer is supported by sufficient and verifiable evidence.
Skincare results, skin feel and tolerability can vary from person to person. Skin condition, skincare routine, amount used, frequency of use, other products used and individual factors may influence how a cosmetic product is experienced. A specific individual result therefore cannot be guaranteed.
Scientific information about our mineral approach
On our website, we provide scientific context for sodium, calcium, magnesium and strontium. The following publications are the sources for this ingredient-related background information. What matters in each case is what was actually investigated.
Important: The following studies are not clinical studies of our finished SOURCE LAB products and do not constitute general evidence of efficacy for our mineral complex. They support only the relationships actually investigated in the respective publication.
Sodium – moisture environment of the stratum corneum
Publication:
Watabe A, Sugawara T, Kikuchi K, Yamasaki K, Sakai S, Aiba S.
Sweat constitutes several natural moisturizing factors, lactate, urea, sodium, and potassium.
Journal of Dermatological Science. 2013;72(2):177–182.
DOI: 10.1016/j.jdermsci.2013.06.005 · PMID: 23871424
Calcium – skin cell maturation and epidermal barrier processes
Publication:
Bikle DD, Xie Z, Tu CL.
Calcium regulation of keratinocyte differentiation.
Expert Review of Endocrinology & Metabolism. 2012;7(4):461–472.
DOI: 10.1586/eem.12.34 · PMID: 23144648
Magnesium – hydration and roughness in a magnesium-rich salt solution
Publication:
Proksch E, Nissen HP, Bremgartner M, Urquhart C.
Bathing in a magnesium-rich Dead Sea salt solution improves skin barrier function, enhances skin hydration, and reduces inflammation in atopic dry skin.
International Journal of Dermatology. 2005;44(2):151–157.
DOI: 10.1111/j.1365-4632.2005.02079.x · PMID: 15689218
Strontium – burning, stinging and sensory irritation in controlled skin tests
Publication:
Hahn GS.
Strontium is a potent and selective inhibitor of sensory irritation.
Dermatologic Surgery. 1999;25(9):689–694.
DOI: 10.1046/j.1524-4725.1999.99099.x · PMID: 10491058
Dermatest: what the rating means
References to Dermatest testing or the rating “very good” relate exclusively to the subject and result of the respective test performed on the specific product tested, in particular its assessed skin tolerability.
Such a rating does not demonstrate that a product treats diseases, has therapeutic effects or is equally well tolerated by every person.
When medical advice is important
Cosmetic skincare cannot replace medical assessment. In cases of known or suspected skin disease, persistent or recurring symptoms, pronounced inflammation, pain, weeping or open skin areas, severe or unusual reactions or unexplained skin changes, medical or dermatological advice should be sought.
If clear intolerance reactions occur during use, the affected product should initially be discontinued and the cause should be medically assessed if necessary.
Communicating clearly – without making research sound stronger than it is.
We therefore deliberately distinguish between the cosmetic effect of a finished product, the known physiological role of a substance in the skin and findings from scientific research on individual ingredients or test formulations.
Legal basis for cosmetic advertising claims
Cosmetic product claims are governed in particular by Article 20 of Regulation (EC) No 1223/2009 and the common criteria set out in Regulation (EU) No 655/2013. These require, among other things, that cosmetic claims are truthful, supported by evidence, fair and understandable to consumers.
Properties of an individual ingredient must not create the impression that the finished product automatically has the same properties. Where an ingredient property is transferred to the finished product, that transfer must be supported by sufficient and verifiable evidence. The effect of a product must also not be presented as stronger than the available evidence allows.
Legal basis & official sources
This page is intended to provide transparent context for our cosmetic communication and scientific sources. A general disclaimer cannot make a specific claim compliant if that claim, in its individual context, goes beyond the available evidence. We therefore assess statements about individual products and ingredients separately and in the context of the evidence available in each case.
