Hydrated, smooth skin is the perfect base for fake tanning. In the past, fake tan formulas were heavy, rich and felt greasy on the skin but recently developments in formulas have created self tanners which hydrate and add a golden glow to your skin in one simple step. Focus on one body part at a time, gently massaging the tanning water into your skin before moving on to the next area. Prior to the introduction of the basic chromium species in tanning, several steps are required to produce a tannable hide. The pH must be very acidic when the chromium is introduced to ensure that the chromium complexes are small enough to fit in between the fibers and residues of the collagen. Once the desired level of penetration of chrome into the substance is achieved, the pH of the material is raised again to facilitate the process. This step is known as basification. In the raw state, chrome-tanned skins are greyish-blue, so are referred to as wet blue. Chrome tanning is faster than vegetable tanning (less than a day for this part of the process) and produces a stretchable leather which is excellent for use in handbags and garments. Unhairing agents used at this time include sodium sulfide, sodium hydroxide, sodium hydrosulfite, calcium hydrosulfide, dimethyl amine, and sodium sulfhydrate. The majority of hair is then removed mechanically, initially with a machine and then by hand using a dull knife, a process known as scudding. Deliming and bating The self-tanning serum is the perfect addition to your skin care routine. It can be added to your daily moisturizer for a kiss of color that you can customize by modifying the number of drops you use. This serum is formulated for safe use on both the face and body, plus it is non-comedogenic so you don’t need to worry about clogging your pores in the process.

Tanning is the process of treating skins to produce leather. Before the Industrial Revolution, tanning was a particularly smelly "odoriferous trade". Often dung and urine were used in the process; it was common for children to be employed as dung gatherers and for there to be ' piss-pots' on street corners to collect urine for use in tanneries.[ 1] Along with a tanning water mousse, SOL by Jergens Sunless Tanners offers everything you need to get your perfect, safe, sunless tan started: The tanning process involves chemical and organic compounds that can have a detrimental effect on the environment. Agents such as chromium, vegetable tannins, and aldehydes are used in the tanning step of the process. However, other processes and chemicals are involved. Chemicals used in tanned leather production increase the levels of chemical oxygen demand and total dissolved solids in water when not disposed of responsibly. These processes also use large quantities of water and produce large amounts of pollutants. Tanning increases the spacing between protein chains in collagen from 10 to 17 Å. The difference is consistent with cross-linking by polychromium species, of the sort arising from olation and oxolation.To prevent damage of the skin by bacterial growth during the soaking period, biocides, typically dithiocarbamates, may be used. Fungicides such as 2-thiocyanomethylthiobenzothiazole may also be added later in the process, to protect wet leathers from mold growth. After 1980, the use of pentachlorophenol and mercury-based biocides and their derivatives was forbidden. Liming Historically the actual tanning process used vegetable tanning. In some variations of the process, cedar oil, alum, or tannin were applied to the skin as a tanning agent. As the skin was stretched, it would lose moisture and absorb the agent. A universal colour, subtle apple fragrance and formulated with hyaluronic acid for extra hydration. For a more subtle tan, apply fewer drops and for a darker tan, add more drops.

The isoelectric point of the collagen in the hide (this is a tissue-strengthening protein unrelated to keratin) is also shifted to around pH 4.7 due to liming. Unhairing and scudding Tanning is the process of treating skins and hides of animals to produce leather. A tannery is the place where the skins are processed. The tanning process begins with obtaining an animal skin. When an animal skin is to be tanned, the animal is killed and skinned before the body heat leaves the tissues. This can be done by the tanner, or by obtaining a skin at a slaughterhouse, farm, or local fur trader. Wet white is a term used for leathers produced using alternative tanning methods that produce an off-white colored leather. Like wet blue, wet white is also a semifinished stage. Wet white can be produced using aldehydes, aluminum, zirconium, titanium, or iron salts, or a combination thereof. Concerns with the toxicity and environmental impact of any chromium (VI) that may form during the tanning process have led to increased research into more efficient wet white methods.

A tannery may be associated with a grindery, originally a whetstone facility for sharpening knives and other sharp tools, but later could carry shoemakers' tools and materials for sale.

Tanners would place scraps of hides in a vat of water and let them deteriorate for months. The mixture would then be placed over a fire to boil off the water to produce glue. Before tanning, the skins are unhaired, degreased, desalted and soaked in water over a period of 6 hours to 2 days. Historically this process was considered a noxious or "odoriferous trade" and relegated to the outskirts of town.

For best results, use our Revolution Glow Tanning Brush to Apply the Face Drops. Mix with moisturiser and apply evenly to the body after cleansing. Wash hands after application, no need to wash off body until your next cleansing routine. At maximum, mix 10-15 drops with your everyday moisturiser. Use daily for 7 days to build your tan up and then as and when required to maintain your glow. In soaking, the hides are soaked in clean water to remove the salt left over from curing and increase the moisture so that the hide or skin can be further treated.The first stage is the preparation for tawing. The second stage is the actual tawing and other chemical treatment. The third stage, known as retawing, applies retawing agents and dyes to the material to provide the physical strength and properties desired depending on the end product. The fourth and final stage, known as finishing, is used to apply finishing material to the surface or finish the surface without the application of any chemicals if so desired. Health and environmental impact After soaking, the hides and skins are taken for liming: treatment with milk of lime (a basic agent) that may involve the addition of "sharpening agents" (disulfide reducing agents) such as sodium sulfide, cyanides, amines, etc. The objectives of this operation are mainly to: The weakening of hair is dependent on the breakdown of the disulfide link of the amino acid cystine, which is the characteristic of the keratin class of proteins that gives strength to hair and wools (keratin typically makes up 90% of the dry weight of hair). The hydrogen atoms supplied by the sharpening agent weaken the cystine molecular link whereby the covalent disulfide bond links are ultimately ruptured, weakening the keratin. To some extent, sharpening also contributes to unhairing, as it tends to break down the hair proteins.
