Hyaluronic acid is used effectively to maintain the freshness and hydration of the skin and therefore it is used by cosmetic and skin care doctors during their treatment plans for facial wrinkles, and dry skin problems, as hyaluronic acid has a tremendous ability to absorb water up to 1000 times its weight of water, so, it traps water and stabilizes it in the skin, and then redistributes it As needed. Hyaluronic acid is a natural acid found in the body of all its organs, and in particular it affects the skin and connective tissues in the joints, as it works to support the layers of skin below the collagen that connect with each other to form connective tissue, which is known as molecular sponge, and is also characterized by its sticky nature, It helps lubricate the joints, making them is easy to move and giving them the desired shape. The average human body contains about 15 grams of hyaluronic acid, but a third of this acid is consumed daily in the body, and replaced continuously until the age of thirty so the acid is not renewed at the same rate, but rather begins to decrease and is said that by the age of fifty, almost half of the body's supply of it has been lost, This, in turn, causes the complexion to lose its elasticity and softness. This acid stores the water in the skin, and maintains its moisture, which explains the use of hyaluronic acid for the skin as it maintains its moisture and youth. Because it has a tremendous capacity to absorb water equal to a thousand times its size, it maintains it and distributes it to cells, body tissues, and the first layers of the skin.

The benefits of hyaluronic acid for the skin are numerous, which made it among the options for the freshness of the skin announced by cosmetic clinics, other than most medical and skincare products contain the same acid, also it stores the moisture in the body naturally, thus helping to restore skin elasticity, especially for those over the age of 35. It contributes to filling the skin's voids and thus reduces the appearance of wrinkles and lines. Hyaluronic acid penetrates the upper layers of the skin and reaches the dermis below collagen, and is therefore considered one of the best deep moisturizers for the skin.

As well Hyaluronic acid stimulates stem cells to produce new, more youthful cells, and thus a greater amount of collagen, which maintains the skin's youth and elasticity. It allows the accumulation of the important protein to support the cells under the skin, thus feeding the skin cells through the capillaries, It is used to moisturize the skin as it not only permeates the skin, but its location near the outer skin layer allows for increased skin elasticity and keeping the skin smooth and healthy, Its results are immediate and can be seen quickly, especially in the case of injection sessions. It helps improve joint strength and overall body health and protect the skin from the UVB rays of the sun as well as the reactive oxygen types it generates, which can cause tanning. It is used to enlarge and blow the lips as well as the cheeks, and Helps repair damaged cells and damaged tissues due to age, at the same time It Enhances collagen content in connective tissues. It is an effective treatment to a prevent skin fungi that affect the surface of the skin. Helps restore radiance and radiance to the sun damaged skin and from smoking if mixed with cosmetic injections with a number of other vitamins that nourish the skin, and use those syringes in the area of the forehead or lips and eye wrinkles. It plays an effective role as an anti-oxidant, as it traps the free radicals that lead to skin ageing.

There is more than one method that guarantees you to obtain a good percentage of hyaluronic acid for the skin, and that percentage varies according to the method, and the extent of the body's susceptibility to it, and this is what the doctor determines based on the nature of each case. Hyaluronic acid is also available in the form of injections, so the hyaluronic acid itself is injected either in the forehead area to treat the signs of ageing and wrinkles, as hyaluronic acid fills the surface wrinkles in an automatic way, and those deeper such as those caused by the loss of subcutaneous fat as in the lips or cheeks Note that this feature is limited to injection. The use of hyaluronic acid injections are related to the extent of its hardening, as the molecules composed of hyaluronic acid are linked with chemical bridges between them. Hyaluronic acid can also be used to inject lips that suffer from chronic dryness, after the injection session the lips swell for about 48 hours, and moisturizing in the depths appears after a week of the injection session and the effect of the injection lasts from 4 to 8 months. While some doctors prefer to use hyaluronic acid with another group of vitamins and minerals to make small, separate surface injections on the face, neck, and hands to work to combat signs of ageing, these injections are ideal treatment for women who smoke or have significantly affected skin due to excessive sun exposure, as it can improve Skin quality enhances its radiance and radiance. For injections filling the wrinkles into the forehead and around the mouth, the doctor initially applies an anesthetic cream to the skin, before injecting thick (somewhat) hyaluronic acid into the wrinkles, auras, or deep cavities, and then gently massages the areas that have been pricked with needles to distribute the product in an equal manner, usually The effect of this injection lasts about 12 months. As for volume-amplified injections such as used to enlarge the lips or cheeks, the thicker hyaluronic acid is used to fill the lips or temples, and the effect lasts about a year and a half.

Thanks to its effective role in moisturizing and revitalizing the skin cells, there are creams containing hyaluronic acid for different skin available in pharmacies, the most important when choosing to choose the preparation with a liquid or serum formula if your skin is oily, but if your skin is dry or advanced in age, it is better to choose a cream with creamy composition.

It should also be noted when choosing creams containing hyaluronic acid for the skin that the smaller the molecule of hyaluronic acid, it penetrates deeper into the skin, while large hyaluronic acid settles in the upper layer of the skin and forms as a protective film.

Creams containing hyaluronic acid for the skin are also an ideal choice to protect the skin from external factors (such as exhausts, climatic fluctuations, the sun and the effect of cigarette smoke). Therefore, these creams can be used for young women and women of age at the same time, as they are used in night and day creams alike.

Scarring from acne is one of the most vexing problems in dermatology. Unlike other areas of cosmetics, it is borne from a medical condition and affects individuals of varying ages. It can negatively affect one’s economic and social opportunities and be devastating to self-esteem. While prevention may be the best cure, access to medical care, compliance, and the increased frequency of adult acne all increase the likelihood of scarring from inflammatory and nodulocystic acne. There are myriad treatments for acne scars like the acne marks cream.

 Unfortunately, there is not a ‘‘magic’’ bullet. The evidence is rather poor even for laser resurfacing. Part of the difficulty lay in the various topographic shapes and forms in which acne scars come. A practitioner needs to know what he/she is treating in order deliver the proper therapy. The biggest advantage with fractional devices is that those with high Fitzpatrick skin types can be treated with less risk of postoperative sequel. 

Yet it can require many treatments and using products for acne scars, and the final results may not be evident for several months after the final treatment because of continued collagen remodeling. The chapters on treating patients of color are much needed with recommended best acne scars removal products.

As well as the normal scars there is Rolling scars are a common type of scarring that can occur as a result of the acne healing process.

They appear as indents in the skin and tend to measure a few millimeters wide. They are defined by their sloping edges, giving the skin a wavy, uneven appearance and aren’t always the same size as the original acne lesion that caused them, as the size depends on how the skin heals Rolling scars are more common in areas of the face where the skin is thicker, such as the lower Cheeks and jaw.

Like all acne scars, the formation of rolling scars is largely dependent on how your skin heals. If you tend to scar easily then you are more likely to develop acne scars and you have to use the acne control cream . Inflammation also plays a key role in development of acne scars. The deeper that inflammation from an acne lesion reaches into the skin the more likely it is to scar upon healing. This is one of the reasons that it is important to treat acne as soon as possible, to lower the risk of deep inflammation.

Picking or squeezing acne lesions can damage the skin and lead to an increased chance of scarring. It is not advised that you pick at or squeeze your acne. You are also more likely to develop acne scars if you smoke, as smoking leads to an increased risk of scarring in general.

It is often claimed that periorbital dark circles are caused by tiredness or working too hard or even just staying up late. While this can be true, the truth is that your genes play a huge role here.

Simply put, dark circles are a result of the thin layer of skin below your eyes showing the blood vessels and the blood they contain more clearly than anywhere else on your body. (For reference, this skin around your eyelids, called periorbital skin, is on average about 0.5 mm thick compared to an average of about 2 mm thick on most of the rest of your body.) That is the mean reason you have to choose the best under eye cream for the dark circle.

Now, the reason veins often look blue isn't because the blood inside them is blue; it's because your skin/subcutaneous tissue only lets blue/violet wavelengths of light pass through it. As a result, only blue light is reflected back and the veins look, well, bluish. (Veins often won't appear blue if a person has darker or lighter skin. Rather, the veins tend to appear green or brown. On the other hand, people with extremely light skin, will typically have veins that show up as dark purple or dark red, more closely resembling the actual color of the blood running through the veins.)

It's the exact same concept with the skin below your eyes. Those dark circles are (usually) just the result of light being reflected back off of the blood vessels sitting just below the surface of that incredibly thin patch of skin. This is the same reason facial bruises are more prominent below or around the eyes; the thin skin just shows the blood from the ruptured blood vessels a little bit more clearly.

Again, as we age, our skin loses its elasticity and ability to regenerate and as a result, it becomes thinner. This is why more often than not, elderly people will have rather prominent periorbital dark circles regardless of how much they sleep. As with those who are genetically predisposed to having thinner skin below the eyes, it's important to start early use the best under eye cream for dark circles.

Another thing that can cause dark circles beneath the eyes is something known as periorbital hyper-pigmentation, which is basically a condition that results in more melanin being produced by the skin below the eyes, resulting in it appearing to be a darker color. This is mostly a condition that affects (or is at least more noticeable in) darker skinned people. 

Another problem that goes hand-in-hand with periorbital dark circles is periorbital puffiness, aka bags below your eyes. In young folk, this is almost always caused by fluid buildup below the eyes, either due to illness, allergies or simply excessive salt consumption which can result in the body retaining more fluid than usual. This can place increased pressure on the skin and blood vessels around the eyes which can force blood vessels closer to the surface of the skin, making dark circles appear more prominent. Eye puffiness can also simply be a result of old age which you can perfectly solve by choose the best under eye cream for dark circles.

Now we explain if those dark circles be caused by fatigue.

Well sometimes yes, but It's not like lack of sleep makes your skin thinner.

It's how the body acts when it's low on energy. When the body is tired, production of the chemical cortisol is dramatically increased to help give you the energy you need to stay awake. Among many other things, cortisol actually increases the volume of the blood in your body, which causes the blood vessels (including the ones below your eyes) to engorge to accommodate it. As we've already mentioned, dark circles are mostly caused by us seeing our blood vessels / blood through our skin, so it stands to reason that when those blood vessels are engorged, they'd be easier to see, even in people who may have been blessed with thicker skin below their eyes.

So, whether by passing on their genes to you or for not letting you sleep in after a gaming all-nighter when you're young, it's all your parent's fault. Something that is/was even more reckless of them as cortisol promotes fat accumulation. So your lack of sleep is likely contributing to more than just under-eye cosmetic issues.
