Documented effect means that the products' effect has been examined and found to be valid in clinical studies, carried out by an independent, third-party dermatological testing laboratory.

Dermatological means that the test results are examined and assessed by dermatologists, i.e. dermatologists.

Third-party and independent means that the testing laboratory is not involved in the development or sale of the products, and that their financial earnings are not affected by the results of the clinical studies.

The testers have received the product in a white sample tube without a logo or name, so they do not know which product or skincare brand they are testing.

The clinical studies have different setups depending on what is being investigated. In the long-term studies, the products are used as the only skin care product, morning and evening, daily for 8 weeks.

The results have been obtained by examining the test subjects' skin with, among other things, advanced 3D skin scanners and other measuring instruments, before and after the test period. No placebo was used. Instead, the results in the effect studies have been obtained by comparing them with the skin care routine that the test subjects used before.

"Skin irritation test" or "Skin tolerability test" is a dermatological test for assessing the skin's tolerance for the product.

Method : The product is applied to the skin with a protective membrane covering it. In this way, the moisture in the product is preserved and the cream stays on the skin without drying out. This reinforces the cream's effect on the skin. The product remains on the skin for 48 hours after which the membrane is removed. The skin is assessed by an independent dermatologist 30 minutes after the occlusion/membrane has been removed and again after 72 hours. If there have been signs of irritation, the test subject's skin is assessed once more after 96 hours. The dermatologist assesses whether there are signs of irritation and looks for, among other things, redness, swelling, bumps, blisters and skin damage. Based on the results, the product is classified as either non-irritating, slightly irritating, moderately irritating and highly irritating.

WHO IS THE PRODUCT TESTED ON
Below are examples of results for WASH the day off facial cleanser:

• The product has been dermatologically tested on 75 people aged 21 to 69 years.
• 9% (7 out of 75) of the test subjects were men and 91% (68 out of 75) were women.
• 33% of the test subjects have known allergic/atopic (sensitive) skin.
• The test subjects predominantly had skin phototype 2 (Fitzpatrick scale 2)

Result:

All our products have been tested with the "Skin tolerability test".

None of the test subjects showed any signs of an allergic reaction, irritation, redness or swelling, either after 30 minutes or 72 hours. The products are well tolerated and can be classified as non-irritating also for people with atopic/allergic (sensitive) skin.

Tightness and elasticity are biomechanical properties of the skin that are measured using an advanced measuring instrument, Cutometer®. Cutometer® is one of the most recognized and most widely used measuring instruments in dermatology for assessing skin tightness and elasticity. The instrument creates an air suction, i.e. a negative pressure, which the skin is exposed to for a short period. While the skin is exposed to the pressure changes, the instrument's optical parts measure the skin's movements. The skin's resistance to movement when exposed to suction is a measure of skin tightness. The skin's ability to restore its original shape when the suction ends is a measure of the skin's elasticity.

Method:

Test subjects are instructed to stop using other face creams/serums and the like when the test period starts. The test subjects apply the test product to their face twice a day, as the only skin care product, for 8 weeks. The skin's firmness/tightness and elasticity are measured on day 0, and then after 8 weeks. Measurement of the skin's tightness/firmness and elasticity takes place at both times in a room with a temperature of 20±2oC and a humidity of 50±10%, so that the result is not affected by the surroundings. The results of the measurements before and after 8 weeks of using the test product are then compared. In the clinical study, the effect of the test product is compared in this way with the skin care the test person has used in the past.

Wrinkle length and wrinkle depth can be measured with a Visioline® VL 650 measuring instrument. The measuring principle is based on the skin's relief, and thus wrinkles, being replicated using a material called Silflo®. The wrinkles, which normally go down into the skin, will be raised on the replica like a microscopic "mountain" rising up. These "mountains" are illuminated at a special angle so that shadows are formed. The shadows are measurable and visualized using a camera. The measured shadows are used as a basis in mathematical models, so that quantitative measures of wrinkle parameters such as depth and length of wrinkles are obtained.

The test subjects apply the test product to their face twice a day, as the only skin care product, for 8 weeks. Wrinkle parameters are measured on day 0, and then after 8 weeks. Measurement of the skin's wrinkles takes place at both times in a room with a temperature of 20±2oC and a humidity of 50±10%, so that the result is not affected by the environment.
