Hyaluronic Acid Serum
A moisturized skin is young-looking skin, and that is why cosmetic products that provide skin with deep moisture are part of the beauty routine of women worldwide. Hyaluronic acid is a highly praised moisturizing ingredient as it makes the skin look supple, plump, glowing, and rejuvenated. Hyaluronic serums are gaining more visibility in the hyaluronic acid products line-up, as they are a notable ally in the fight against aging.
What are the Main Benefits of Hyaluronic Acid for the Skin?
Hyaluronic acid, also known as hyaluronan (or HA), is a glycosaminoglycan (GAG) – basically a type of sugar that naturally occurs in our body – mainly in the skin. HA can hold a thousand times its weight in water, preserving it into the skin layers. It also acts as a humectant, drawing moisture from the surrounding environment and preventing the existing one from evaporating. This feature enables hyaluronan to provide around-the-clock hydration for the skin. However, as we age, hyaluronic acid in the skin depletes, and the need to include hyaluronic acid supplements in our beauty routine increases.
Hyaluronic Face Serum
Hyaluronic acid in serums provides the top layer of the skin (epidermis) with enough hydration to last throughout an entire day.
Compared to other substances used in skincare, hyaluronic acid has a superior anti-aging effect by:
- helping the skin regenerate better;
- improving its elasticity;
- smoothening the skin’s texture;
- providing a silky and youthful appearance.
Natural hyaluronic acid serum has to be applied once per day on damp skin, as HA needs moisture to seize water and penetrate the deep layers of the skin for optimum rejuvenating effects.
How does Hyaluronic Acid Boosting Serum Work?
Hyaluronic acid boosting serum is a high-power rejuvenating cosmetic product, especially when paired with vitamins, retinol, and other substances that make the skin look fresh and young. HA also stimulates the natural production of collagen and elastin, two different substances with powerful anti-aging effects.
A review of studies published in 2018 indicated that HA formulations (such as serums) combined with lidocaine and other co-agents reduced the wrinkle scars, improved skin elasticity, and hydration and boosted face rejuvenation and volume restoration.
This serum also tightens the skin in the eye area, as the skin absorbs up to 60% of the nutrients contained in the serum.
Moreover, it can reinforce the natural barrier of the skin that prevents toxins from penetrating the skin. UV rays, pollution, smoking can all cause wrinkles, dryness of skin, and dark spots. The skin’s lipid barrier (fatty acids that prevent irritating agents from reaching the skin) becomes less effective as we grow old. HA helps protect this lipid barrier by rendering its toxins blocking capacity, a good reason for those with sensitive skin or who are affected by acne to use hyaluronan serums.
Is Retinol and Hyaluronic Acid Serum Effective?
Retinol, a vitamin A derivative, is an anti-aging cosmetic staple as it helps reduce wrinkles and fine lines. Retinol converts to retinoic acid when it penetrates the skin, a compound effective in treating acne and hyperpigmentation.
One study suggests that retinol increases the production of HA in the dermis, which can decrease the signs of facial aging.
Retinol and hyaluronic acid serums provide to your skin the benefits held by both retinol and HA:
- reduce fine lines and wrinkles;
- decrease dryness;
- prevent exfoliation;
- provide hydration and softness.
A clinical study indicates that a cream containing retinol and HA improved the appearance of crow’s feet fine lines and under-eye, crow’s feet, forehead, and cheek wrinkles. The effect lasted four weeks after the use of the cream. Moreover, after eight weeks of use, the same cream decreased brown spots and sun damage signs and improved skin radiance.
How to Choose the Best Hyaluronic Acid Serum
The cosmetic market is filled with HA serums, but not all these serums are made the same way or provide the same type of benefits for your skin.
What you should be looking for when shopping for a hyaluronic acid serum is:
- The Proper Concentration of HA
A concentration in the range of 0.25 to 1.75% is often not effective enough. It will, no doubt, hydrate your skin, but not to the extent you need it to.
At the other end, a concentration too high can cause hyaluronan to take the moisture it needs from your skin (as it attracts water molecules), making the serum a clear “DON’T USE” variant.
A balanced concentration is one that slightly exceeds 2%. This concentration hydrates your skin by keeping the water molecules present in the serum, hence fulfilling its purpose.
- The Right Molecule Weight of HA
Research has established that molecules of hyaluronic acid differ from big molecules to medium and low-weight ones. Many HA serums in the market contain only one of these forms.
If you need a short-term improvement of your skin’s appearance, you can choose a high-weight molecule HA serum, as the molecules in this variant don’t penetrate the deep layers of the skin but stay on its surface. This option is suited when you want your skin to be plumped and hydrated for an event when you want to look your best.
Medium weight molecules slightly penetrate the skin below its barrier, providing an improved look of your skin for the medium term. This is possible thanks to the hydration medium-weight HA molecules grant your skin.
Low-weight hyaluronan molecules go deep into the skin’s texture and structure and successfully treat wrinkles, fine lines and restore elasticity. The results of these molecules weight HA are effective in the long term.
The best hyaluronic serum is the one that combines these molecule weights, as they make the skin look younger, more hydrated, plumped, and smooth for both the short term and long term.
Conclusion on Hyaluronic Acid Serums
Hyaluronic acid face serums are easily absorbed by the skin, its compounds fighting efficiently against aging and other skin problems. Incorporating a HA serum into your daily beauty routine will enable you to enjoy rejuvenated, hydrated, smooth-looking, and plumped skin.
