Your skin is the largest organ of your body, designed to protect against external harms, regulate body heat, and manage nutrient levels and water loss. It’s composed of 3 layers:

• The epidermis, the outermost layer, provides a waterproof barrier and creates our skin tone.
• The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
• The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

For a topical product to work it not only has to penetrate the skin but get absorbed too.

Skin Penetration represents the amount of a topically applied ingredient that exists between the top layer and bottom layer of your skin, during penetration the body does not yet absorb the ingredient, and it cannot affect the body systems.

Skin Absorption occurs when the topically applied ingredient penetrates the skin barrier.

The active ingredients in SteelFit® products are permeable, meaning they both penetrate and are absorbed by skin cells where they are processed and circulated.

That heat and tingle when you apply the products is actually the active ingredients increasing energy to the topical area, allowing the ingredients to absorb more efficiently and also sending signals to that area, hence spot reduction.
