|Rosemary||Compounds from rosemary fight against mutagenic effects of radiation, while the botanical fragrance has powerful aromatherapeutic benefits.In two separate studies, scientists in Spain found that nothing fights radiation damage to micronuclei like a simple garden herb known as rosemary. They noted that ionizing radiation causes the massive generation of free radicals that induce cellular DNA damage. They studied the protective effects of several compounds against gamma ray induced chromosomal damage in micronuclei testing by adding various compounds to human blood before and after irradiation. When the compounds were added after gamma irradiation treatment, the protective effects relied not on scavenging ability, but on activity against free radicals already present in the cells, such as lipoperoxy radicals which are mainly responsible for continuous chromosomal oxidative damage.Rosemary is associated with feelings of contentment. It’s been shown to have positive affects on performance and mood. Rosemary has also demonstrated the ability to reduce cortisol levels. This means that rosemary aromatherapy can be a good choice for maintaining blood sugar levels and a healthy immune system.|
|Saccharide Isomerate||Saccharide Isomerate acts as a highly effective moisture regulator resulting in long-lasting water retention in skin. Saccharide Isomerate imparts its moisture-attracting properties by binding to the free amino groups of lysine in the keratin of the stratum corneum.This special type of binding leads to a unique substantivity and affinity to skin. Once bound to the skin surface,|
Saccharide Isomerate cannot be washed off easily. Therefore the removal of Saccharide Isomerate occurs only by the natural process of desquamation.The main feature of Saccharide Isomerate, however, is its highly effective moisture-regulating capability. Saccharide Isomerate’s capacity for long-lasting moisture binding and moisture retention makes it a true treatment ingredient. For this reason, Saccharide Isomerate is very effective in dry air under low relative humidities. Under these conditions there is a particular need for a real functional moisturizer.Saccharide Isomerate’s unique water-magnet-like action holds water tenaciously and doesn’t let it escape. This unique property distinguishes it from conventional hygroscopic substances which are unable to function at such low relative humidity levels. On the contrary, these humectants will draw moisture out of the skin at low relative humidity levels, which may impart undesired dryness to the skin surface.Saccharide Isomerate is a choice preventative ingredient to protect dry skin against classical symptoms such as brittleness, roughness, unevenness, faintness and itching.
|Seaweed Gel or Algae||Seaweed Gel plays an important role in hydration and improves cell metabolism.|
|Sodium Hyaluronate||Hyaluronan, commonly referred to as Hyaluronic acid, is a major component of skin, where it is involved in tissue repair. When skin is exposed to excessive UVB rays, it becomes inflamed, or sunburned, and the cells in the dermis stop producing as much hyaluronan. This can increase the rate of skin’s degradation. The skin is the largest organ in the body comprising about 15% of the body weight. Roughly 50% of the Hyaluronic acid in our body is found in the skin. Hyaluronic acid and Collagen are vital to maintaining the skin’s layers and structure. It is the collagen that gives the skin its firmness, and Hyaluronic acid that nourishes and hydrates the collagen.Hyaluronic acid is a linear biopolymer belonging to glycosaminoglycans (GAGs). Primary structure of Hyaluronic acid is constituted by a repetitive disaccharide unit of sodium glucuronate and N-acetyl glucosamine, linked by a Î² (1-3) bond. Hyaluronic acid that is 15.000 – 50.000 Da normalizes hydration. It limits trans epidermal water loss by reinforcing tight junctions between keratinocytes of the stratum granulosum.|
The special Hyaluronic acid used in our Previse recipe stimulates the expression of ZO1 and Occludin proteins that are constitutive proteins of tight junctions. This improves cell cohesion and the barrier function of the skin. Moreover, thanks to the high hygroscopic ability of the Hyaluronic acid, it maintains hydration in the skin through a water reservoir function in the dermis.
Through both of these complementary actions, Hyaluronic acid regulates the internal hydration of the skin and improves firmness by stimulating collagen in the dermis.
|Soybean (Glycine Soja) Seed Extract||In vitro results showed the following key benefits to the skin:|

|Vitamin B5 (Panthenol)||Panthenol is the provitamin of D-Pantothenic acid (vitamin B5).One form of Panthenol is D-Panthenol, an active, biologically stable form of Pantothenic acid. It plays a fundamental role in the metabolism of all cells. D-Panthenol is used in some sophisticated cosmetic skin care and hair care products to improve the appearance of skin, hair, and nails.Topically applied Panthenol is absorbed by the skin and transformed into Pantothenic acid (G. Stuttgen, H. Krause, Arch. Klin. and Exp. Dermat, 209, 578-82 (1960)). D-Pantothenic acid plays a key role in the human intermediary metabolism. It is a part of the Coenzyme A. Deficiency of vitamin B5 results in dermatological disorder.|
