What the manufacturer claims
Iv San Bernard builds the DERM line as a three-step system: DERM Shampoo Y6, Z5 conditioner and X7 oil. The conditioner should calm the skin after washing and bring softness back to the coat. The manufacturer asks users to read the instructions before use.

Cons and what to watch
- No ingredient list. Apart from St John's wort, nothing is named.
- Medical promises. "Relieves inflammation and supports coat growth" is no substitute for treatment.
- Works as a set. It is designed for Y6 shampoo, not any shampoo.
- Errors in the name. The listing title mixes languages.
When cosmetics are not enough
Itching, redness, flaking and hair loss are symptoms behind which there may be fleas, allergy, fungus, bacterial infection or hormonal disorders. The conditioner can make the skin more comfortable and soften the coat, but it will not remove the cause. If symptoms last more than a week, get worse, or you see sores, weeping areas or a bad smell, see a vet.
How to use the DERM line
First wash your pet with DERM Y6 shampoo. Then apply Z5 conditioner to the coat, massage gently and leave for 5 minutes. Rinse thoroughly. Before drying with a hair dryer or towel, apply DERM X7 oil to the skin if needed. The manufacturer also suggests adding a few drops of the oil directly to the line's shampoo and conditioner.
Drying irritated skin
Irritated skin must not be overheated: use the hair dryer on a warm setting and keep it at a distance. Do not rub the coat with a towel — blot it. The less friction, the less itching after the treatment.
St John's wort and sun
St John's wort is known to increase skin sensitivity to sunlight. So after DERM treatments, avoid leaving your pet in direct sun for long right away, especially light-coloured, short-coated animals with exposed skin.
For cats
According to the description, the conditioner suits cats, but rinse it off especially well: cats groom themselves. Cats with skin problems often find bathing hard, so discuss care with a vet first. On bathing, see how to bathe a cat.
Other products for sensitive skin
For everyday care of sensitive skin the brand offers the pH Balance conditioner, and for local itch relief the Derma Gel SOS.
Who it suits
The conditioner suits dogs and cats with sensitive and irritated skin as part of the DERM routine — after consulting a vet if the irritation is caused by a disease. Other products are in Iv San Bernard and shampoos and conditioners.
Verdict
Iv San Bernard DERM Z5 is a St John's wort conditioner for irritated skin, the second step of the Y6 + Z5 + X7 system. The downsides are that the listing gives no ingredient list, and promises to "relieve inflammation" and "speed up coat growth" do not replace treatment.
