Skin also functions as a large storeroom for the body: The deepest layer of skin can store water, fat and metabolic products. And it produces hormones that are important for the whole body.

The primary function of these cells is to create the barrier between you and the rest of the world. Keratinocytes produce the protein called keratin, and by the time the cells have been pushed up from the basement membrane, they are mostly sacks filled with keratin.

Epidermis: The upper or outer layer of the two main layers of cells that make up the skin. The epidermis is mostly made up of flat, scale-like cells called squamous cells. The other main layer of the skin is the dermis, the inner layer of skin, that contains blood and lymph vessels, hair follicles, and glands.

The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.

When covering sensitive parts of the body, such as the eyelids, the epidermis is only 0.05 mm thick, but on heavily used parts of the body, like the palms of the hands or the soles of the feet, this layer can be at least 1.5 mm thick. Thick or thin, the epidermis has five distinct layers or regions.

The epidermis: a thin outer portion, that is the keratinised stratified squamous epithelium of skin. The epidermis is important for the protective function of skin. The basal layers of this epithelium are folded to form dermal papillae. Thin skin contains four types of cellular layers, and thick skin contains five.

Researchers who used a 3D scanner to study overall facial skin and superficial fat thickness in adult cadavers report facial skin tends to be thinnest at the radix and dorsum, at an average 1.51 mm, and thickest in the infraorbital region, at an average 1.97 mm.

Thick skin on the face can be classified as having a rough texture. Thick/oily skin does have an advantage, though, as it tends to age less quickly. The oil production keeps the skin hydrated and prevents it from wrinkling as quickly as people with thinner and drier skin often experience.

In humans for example, the skin located under the eyes and around the eyelids is the thinnest skin in the body at 0.5 mm thick, and is one of the first areas to show signs of aging such as “crows feet” and wrinkles….

13 ways to improve or restore skin elasticity

Fish like mackerel or salmon are rich in omega-3 fatty acids, perking up dull skin and keeping it moisturized. These omega-3 fats can also make your skin thicker and more supple.

Vitamin D is one of the best vitamins for your skin, along with vitamins C, E, and K. Making sure you get enough vitamins can keep your skin looking healthy and youthful.

Foods to Avoid For starters, keep an eye on your sugar and carbohydrate consumption. Both can cause inflammation and damage your skin’s collagen. Instead, prioritize mineral-rich fruits and vegetables, as well as protein-rich animal and plant foods.

The good news is, though you may not be able to bring back the lost collagen, there are ways to help get things moving and slow further loss. With the right skin care products and treatments outside and in, there’s so much you can do to get back that spring back in your skin.

It can often be found in products that are flavored, such as chocolate or fruit flavored. It is hard to definitively say which is better for you when it comes to pills and powder. Besides the capsule, there really is no large difference between these forms of collagen supplement.

PROS: Coming in a tubs or packet, collagen powders are super versatile in that they can be added to almost anything you can think of. Some of the current faves are coffee, smoothies, water, and even your morning omelette. The moment you remember to take it, you can simply pop it into your drink.
