Efficacy testing on PURDERM

Pimples, blackheads or acne can appear during puberty and later, as adult acne. They occur because the skin produces too much sebum – often caused by hormones – and is no longer in balance.

With its nourishing and anti-inflammatory ingredients, PURDERM was specially developed to help oily or acne-prone skin gently return to balance and prevent the appearance of new pimples or blackheads. It helps the skin gradually clarify, leaving it feeling balances and pleasantly nourished.

Lactic acid and malic acid have an anti-microbial effect and boost cell regeneration. Soothing care substances such as alpha bisabolol and allantoin support the improvement of the skin’s general condition and can prevent the inflammation caused by blemishes.

The products of the PURDERM line can also be used as a complement to therapeutic care for acne and adult acne. They are suitable for sensitive skin.

THE STUDY

48 women and two men between the ages of 13 and 66 (average age 25.8); the subjects described their skin as follows (multiple selections possible):


47 tend to have blemishes

34 tend to have pimples

42 tend to have blackheads

29 tend to have oily skin

21 tend to have combination skin

28 tend to have sensitive skin

5 tend to have allergies


The test subjects were asked to use exclusively the product series made available to them for the duration of the observational period (four weeks).

The participants were divided into two groups of 25 members each.

Group A was made up of young participants ages 13 to 18 with blemish-prone skin (papules, pustules, comedones) and a diagnosis of acne vulgaris. They used DADO SENS PURDERM Creamy Cleanser, PURDERM Cleansing Tonic, PURDERM Intensive Gel and PURDERM Cleansing Mask in the morning and in the evening for four weeks. The Cleansing Mask was used two evenings a week instead of the Cleansing Tonic.

Group B was made up of adults ages 19 to 66, likewise with blemish-prone skin, papules, pustules and/or erythema and dry, sensitive and/or oily skin. These individuals had a diagnosis of adult acne (acne tarda) or folliculitis or seborrheic eczema. They used DADO SENS PURDERM Creamy Cleanser, PURDERM Cleansing Tonic, PURDERM Normalizing Cream and PURDERM Cleansing Mask in the morning and in the evening for four weeks. The Cleansing Mask was used two evenings a week instead of the Cleansing Tonic.

The participants then filled out questionnaires about each product.
