The Philosophy that Drives Performance
Every skin and body care product made at Just Jill Cosmetics & Skincare is developed under a set of strict guidelines, a "Creed" that ensures the results you demand - and the clear, resilient and beautiful healthy-looking skin you deserve.
We Use Performance Ingredients at Effective Levels
We use effective levels of performance-proven ingredients, not the “ingredient of the day”. And we use special delivery vehicles that enhance penetration – so you experience dramatic results.
We Use Plant & Mineral Sources
Whenever possible, we choose plant or mineral-derived ingredients, not those from animals or petroleum. We choose multi-functional antioxidants, standardized botanicals, phytonutrients and other performance ingredients. We protect the integrity of these ingredients in the finished product.
We Don’t Use Harsh Ingredients
We never use sodium laurel or laureth sulfates, mineral oil, bovine-sourced ingredients or propylene glycol. We avoid petrolatum, lanolin, solvent alcohols, synthetic color, synthetic fragrance and comedogenic ingredients. We use only gentle preservatives. We do not use formaldehyde-releasing preservatives; you’ll never find imidazolidinyl urea, diazolidinyl urea, quaternium-15, DMDM hydantoin or 2-bromo-2-nitropropane-1,3-diol in any Jack & Jill product. While other companies commonly use these ingredients, they are known to cause skin sensitivity. We limit the use of emulsifiers (like stearic acid, stearyl alcohol and glyceryl stearate) because we’ve found they make dry and sensitive skin more irritable. And, because science has now proven chronic inflammation is the bottom-line of aging, we add soothing ingredients even when irritation isn’t a problem. All Just Jill products are Phthalate-free and Paraben-free.
The only animals we use to test our products are humans, and we do this to make sure your products work.
We Do Extensive Product & Ingredient Testing
Stability Testing. Broad-spectrum microbiology, heat, cold and light stability, and container compatibility are tested before any product is released to market.
Dermatologist-Testing. Repeat Insult Patch Testing (RIPT) on 50 subjects, which is reviewed and approved by board-certified dermatologists.
Ophthalmologist-Approval. Products used around the eyes are subjected to pre-market approval by qualified ophthalmologists.
Ingredient Efficacy Testing. We require our ingredient suppliers to provide proof of efficacy before we review an ingredient for use in our products.
