This disruption helps the primary preservative system in a product work more effectively at lower doses. On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations. Typical use levels in a formula run about 1-5%. Calendula Officinalis Flower Extract comes from the marigold flower and has been used on skin for centuries for its calming effect. In the lab, its active compounds appear to calm inflammation and support the early "healing" phase of minor wounds. This is why Europe's medicines regulator has approved calendula extracts as a traditional remedy for minor skin inflammation and healing small wounds. The stronger human evidence is around would/ulcer care rather than everyday cosmetic claims; a review that pulled together 14 studies found that calendula helped calm the early, inflamed stage of a wound and helped new skin tissue form faster. Two studies also showed it shrank leg ulcers (the kind caused by poor circulation). Results were mixed for burns and for the skin irritation people get from radiation treatment, so it's not a sure thing there. In cosmetics, it's mostly a skin conditioning and soothing agent. The Cosmetic Ingredient Review panel concluded that calendula-derived ingredients are safe as used and that the ingredients are not irritating, sensitizing, or photosensitizing in clinical tests (though they may be mild eye irritants). Typical use levels are quite low; industry data reported it used at under 0.5% (one supplier noted a 10-25% extract blend used at 1-10% in the finished product). Historical use goes up to 10%. The only thing to keep in mind is if you have daisy/ragweed allergies. Calendula is in the same family and one patch-test study found 2% of dermatitis patients reacted to marigold. Be sure to patch test if you have sensitive or allergy-prone skin. Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product. So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation. You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated! This ingredient is used in skincare as a delivery system. It works by "encapsulating" active ingredients with its unique ring shape that is water-loving on the outside and oil-loving on the inside. This improves the stability and absorption of the product into the skin. According to a manufacturer, it also offer some moisturizing effects. Saccharide Isomerate comes from sugars found in corn. It is a skin hydrator. The struc No written reviews yet. Be the first to review this product. Search reviews by skin type, ingredient, or keyword.
