At Bloome, we understand beauty as something uncomplicated, natural, and transparent, designed to enhance your well-being without transforming your essence.
When it comes to facial care and maintaining a fresh, radiant look, understanding what hyaluronic acid does for the skin is essential. This molecule has become a benchmark in aesthetic medicine for its ability to hydrate, restore lost support, and progressively and safely restore skin vitality.
What is hyaluronic acid and where is it found?
A substance naturally present in the body
To understand what hyaluronic acid is, you need to know that it is a glycosaminoglycan molecule that our own body produces. It is distributed in various tissues, although more than 50% of the total amount in our body is concentrated in the skin, specifically in the dermis and epidermis, where it acts as a supporting and hydrating matrix.
Why hyaluronic acid in the skin decreases over time
With the passage of time and the natural aging process, the biological production of this molecule decreases significantly. From the age of 25 or 30, the body synthesizes less hyaluronic acid and degrades it faster due to factors such as solar radiation, oxidative stress, or lifestyle, which leads to loss of firmness and turgor in the skin.
How does hyaluronic acid work on the skin?
Attracts and retains water in tissues
The most prominent property of this substance is its extraordinary hygroscopic capacity: it can capture and retain up to 1,000 times its own weight in water. It acts like a biological sponge that stores moisture in the extracellular matrix.
Helps maintain hydration and elasticity
By keeping water reserves stable in the skin, it promotes an optimal environment for collagen and elastin fibers to maintain their flexibility, significantly improving the elasticity and smoothness of the tissue.
Provides support and volume to certain areas
In addition to hydrating, injectable hyaluronic acid formulas provide a physical support effect. They fill the space between dermal cells, restoring structures that have lost density or volume due to bone and fat reabsorption.
Main benefits of hyaluronic acid for the skin
Improves skin hydration
Restores deep water balance that conventional creams cannot reach in the inner layers of the skin.
Helps smooth lines and wrinkles
By leveling the skin's surface from within, it smooths both fine dehydration lines and static furrows caused by loss of firmness.
Improves the appearance of skin texture
Provides softness and consistency, reducing the appearance of enlarged pores and restoring a more homogeneous surface.
Allows for facial volume restoration
Helps redefine key structures such as the chin, cheekbones, or jawline that lose projection over time.
Promotes a more rested and radiant appearance
By restoring the skin's turgor and natural glow, it reduces the appearance of a tired or exhausted face, reflecting a revitalized look.

What does the hyaluronic acid in creams and serums do?
Topical cosmetics primarily work on the outermost layer of the skin (the stratum corneum). Their main function is to form a protective barrier that prevents transepidermal water loss and superficially smooths texture.
How does injectable hyaluronic acid work?
Aesthetic medicine treatments allow the substance to be deposited directly into the middle and deep layers of the dermis or onto the bone plane. This allows for deep hydration and volume replenishment with high precision.
Differences in depth, objectives, and results
Topical cosmetics offer external hydration, daily maintenance, and dryness prevention. Medical injectable treatment offers structural restoration, static wrinkle filling, volume recovery, and visible, long-lasting results.
What is hyaluronic acid used for in aesthetic medicine?
When asked what hyaluronic acid is used for in aesthetic medicine, the answer covers several objectives depending on the technique and the area:
Deep hydration and improvement of skin quality
Through superficial microinjections (such as facial mesotherapy), dull skin is revitalized, providing radiance and hydration without altering facial volumes.
Filling facial wrinkles and furrows
It is used to diminish pronounced furrows, such as nasolabial folds or expression lines that persist even at rest.
Volume recovery and harmonization
It allows for personalized balancing of facial proportions, restoring lost projection in cheekbones or cheeks.
Profiling and defining specific areas
Helps redefine edges and contours, such as the lip border, nasal tip, or jawline.
Skin areas that can be treated with hyaluronic acid
Lips and perioral area
Allows for defining the lip contour, hydrating the mucosa, and diminishing barcode lines.
Dark circles and eye contour
Fills the depression of the tear trough, reducing the dark shadow that gives a tired appearance. Learn more about dark circle filling with hyaluronic acid.
Cheekbones, chin and jawline
Structures and projects the middle and lower third of the face for a firmer, more defined appearance. Consult cheekbone filler and male facial harmonization treatments available at Bloome.
Nose and facial profile
Through non-surgical rhinoplasty, it allows for quick correction of small deviations or lifting the nasal tip.
Static furrows and wrinkles
Provides support in areas with deep folds, such as forehead lines, the frown lines, or marionette lines.
Neck and décolletage
Improves the elasticity of fine and delicate skin, reducing horizontal folds or "Venus rings" on the neck.

View hyaluronic acidWhen do its effects on the skin start to be noticed?
Results of topical hyaluronic acid
Serums and creams provide an immediate feeling of softness and hydration upon application, although their effect is temporary and requires daily use.
Results of injectable treatments
The change in tissue volume and hydration is noticeable immediately after the consultation.
When can the definitive result be assessed?
The final result is optimally appreciated after 10 to 14 days, a period in which the slight inflammation subsides and the product attracts the necessary water to fully settle.
How long do the effects of hyaluronic acid last on the skin?
Factors influencing its duration
Generally, the effects last between 6 and 18 months. The duration depends on factors such as product density, application depth, each person's metabolism, and lifestyle (tobacco, sun, exercise).
Differences depending on the area and type of treatment
In areas of high gestural mobility, such as the lips, reabsorption is usually faster (between 4 and 8 months in our lip treatments), while in areas of less mobility it can last up to 18 months, as is the case with under-eye filler.
Possible side effects of injectable hyaluronic acid
Inflammation, sensitivity, and small bruises
These are normal, mild, and temporary reactions. It is common to experience slight swelling, redness, or small bruises in the injection area that disappear in a few days.
Possible complications and warning signs
Vascular complications are very rare. The presence of acute pain, skin pallor, or abnormal color changes are signs to contact a doctor immediately.
The importance of personalized medical evaluation
As it is a medical procedure, it must be applied by qualified professionals who evaluate the patient's anatomy and guarantee maximum safety, following the highest standards of medical safety and quality.

Frequently asked questions from clients
What happens to the skin when hyaluronic acid is applied?
The skin immediately regains its hydration reserve, becomes more elastic, regains firmness, and reduces the shading of wrinkles.
Does hyaluronic acid hydrate or plump the skin?
It performs both functions. Low-density gels hydrate and redensify, while highly cross-linked gels allow for projection and volume replenishment.
What is the difference between a serum and injectable hyaluronic acid?
Serum acts superficially on the epidermis to prevent dryness. Injectable acts in the deep dermis to restructure, hydrate, and fill.
How long does it take for hyaluronic acid to take effect?
In injectable treatments, the change is visible immediately, with the final aesthetic result consolidating after 10-14 days.
Can hyaluronic acid be used every day?
In its topical format (creams and serums), yes, it is highly recommended. Injectable medical treatments are scheduled in spaced sessions according to the doctor's indication.
What skin type can use hyaluronic acid?
It is suitable for all skin types (dry, combination, oily, or sensitive), as it is a biocompatible and non-comedogenic component.
Does hyaluronic acid eliminate wrinkles?
It drastically diminishes and smooths static wrinkles by restoring their support. In very deep wrinkles, it substantially improves texture and depth.
How long does hyaluronic acid last on the skin?
The average duration of injectable treatments is between 6 and 18 months, depending on the type of product and the treated area.
