Natural, but actually proven.
Plenty of natural skincare brands talk a good game. Kareen Holland wanted proof.
In July 2016, she engaged an independent, New Zealand-based laboratory to scientifically test a variety of products from the KD One range — skincare, body care, and medicinal. The results validated what customers had been telling her for years.
Today, every new formulation goes through the same kind of independent testing before it carries the KD One name.
The results
Real numbers, not marketing claims.
Hand & Body Cream
Clinical testing proved an antioxidant effect on inflammation of up to 100%. Excess hand-washing with soaps and sanitisers can create chronic inflammation — this cream actively counters it.
Vitamin Enriched Facial Moisturiser with Kiwifruit
Significantly stimulated the production of elastin in skin fibroblast cells — more elastin means improved skin elasticity.
Rich & Intensive Manuka Honey Moisturiser
With UMF16+ manuka honey, this moisturiser stimulated the reproduction of human skin fibroblast cells by up to 45%, promoting overall skin health.
Skin Performance Plus Facial Moisturiser
Testing showed two effects: it stimulated elastin production, improving elasticity and reducing the appearance of wrinkling and sagging; and it stimulated skin cell reproduction by up to 90%.
Vitamin Enriched Facial Moisturiser with Manuka Honey
Loss of collagen weakens skin’s structure. This moisturiser, with UMF16+ manuka honey, was shown to be a strong stimulator of collagen production in human skin fibroblast cells.
Light Hydrating Plus Facial Moisturiser
Significantly stimulated elastin production, supporting improved skin elasticity.
Skin Clear Range
Testing proved an antioxidant effect on inflammation of up to 100%, and showed the range significantly reduces skin inflammation — including the chronic inflammation associated with acne.
Eye Serum
Stimulated skin fibroblast cell reproduction by up to 29% and stimulated elastin production — both contributing to improved skin elasticity around the eye area.
Anti-Pigmentation (Lightening) Serum
Melanocyte cells produce the melanin responsible for skin pigmentation. This serum was shown to reduce melanin production by up to 84%, visibly lightening skin tone.
Recovery Rub
Formulated for tired, aching muscles after exercise. Clinical tests confirmed it reduces inflammation by up to 90%. shop/product/recovery-rub/
Cool Balm
Joint inflammation and swelling happen with both acute injuries and chronic conditions like osteoarthritis. Cool Balm was clinically tested to reduce joint-related inflammation by up to 81%.
Soothing Antiseptic Balm
Formulated to protect sensitive skin affected by allergies, nappy rash, and eczema. Clinical testing proved a response to inflamed cells of up to 80%.
Peppermint Shampoo with Manuka Honey & Blackcurrant
Dandruff and other scalp conditions cause itchiness and inflammation. Clinical tests proved this shampoo relieves scalp inflammation by up to 94%.
