Hyaluronic Acid and Lactic Acid for Intimate Wellness
Vaginal dryness, irritation, burning, and pH imbalance are very common issues that can affect women of all ages. These issues can arise following hormonal changes, drug therapies, the use of harsh cleansers, recurrent infections, or specific life stages such as pregnancy and menopause.
Maintaining the proper balance of the vulvo-vaginal mucosa is a key element of feminine intimate wellbeing. When the vaginal pH becomes unbalanced or the mucosa loses its physiological hydration, discomfort can arise that affects quality of daily life.
Revaginal is a vaginal douche formulated with hyaluronic acid and lactic acid, developed to support intimate hygiene, help maintain physiological vaginal acidity, and support the wellbeing of the vulvo-vaginal mucosa.
Vaginal Dryness and pH Imbalance: Causes and Symptoms
The health of the feminine intimate environment depends on the balance between physiological pH, bacterial flora, and mucosal integrity. Under normal conditions, lactobacilli help maintain a naturally acidic environment, which is one of the main defenses against external aggressors and the proliferation of unwanted microorganisms.
However, several factors can disrupt this delicate balance, including:
- hormonal changes
- menopause
- pregnancy and postpartum
- antibiotic therapies
- stress
- use of harsh cleansers
- recurrent infectious episodes
When the natural defenses of the vaginal ecosystem become weakened, various issues can occur, including:
- intimate dryness
- burning
- itching
- persistent discomfort
- vulvar pain
- abnormal discharge
- discomfort during intercourse
In these conditions, a change in pH can also promote imbalances in the bacterial flora and increase the likelihood of irritation and inflammation.
What Revaginal Is and What It Is For
Revaginal is a vaginal douche designed to support intimate hygiene and help maintain the physiological conditions of the vulvo-vaginal environment. The formulation combines hyaluronic acid and lactic acid, ingredients widely used in products dedicated to hydration and vaginal microbiota balance.
The product can be helpful in the presence of:
- vulvovaginitis
- burning and itching
- local discomfort and sensitivity
- pH imbalance
- dryness
- vulvar pain
- abnormal vaginal discharge
Thanks to the combined action of its ingredients, Revaginal helps maintain the proper level of mucosal hydration, promotes gentle cleansing, and helps preserve the physiological conditions of the feminine intimate environment, especially during periods when it is more exposed to irritation and discomfort.
Lactic Acid and Physiological Vaginal pH
One of the key ingredients in the formulation is lactic acid, a substance naturally present in the physiological vaginal environment.
Lactic acid plays a key role in maintaining vaginal acidity, helping to create an environment that favors lactobacilli and is less favorable to the growth of potentially pathogenic microorganisms.
The lactic acid in Revaginal helps to:
- restore physiological vaginal pH
- support the natural protective barrier
- promote balance in the vulvo-vaginal environment
- help protect against vaginal microbiota imbalances
Maintaining a proper pH is in fact one of the most important elements of feminine intimate wellbeing.
Hyaluronic Acid and Hydration of the Vaginal Mucosa
The formulation also contains high- and low-molecular-weight hyaluronic acid, an ingredient widely used in products dedicated to hydrating and protecting mucous membranes.
Hyaluronic acid is known for its ability to retain water and help maintain tissue hydration. In vaginal formulations, it is used to support the physiological elasticity and wellbeing of the mucosa.
Hyaluronic acid helps to:
- promote hydration of the mucosa
- support normal epithelialization
- promote the mucosa’s natural restorative processes
- provide long-lasting hydration thanks to its adhesion to the vaginal surface
The combination of high and low molecular weight also provides a hydrating and protective effect that is especially valuable in conditions associated with vaginal dryness and irritation.
Scientific Evidence on Lactic Acid and Hyaluronic Acid
The balance of the vaginal microbiota is one of the main natural protective factors for feminine intimate health. Numerous scientific studies have shown that lactobacilli play a key role in maintaining a physiologically acidic vaginal environment, a condition essential for preserving the stability of the bacterial flora and counteracting the growth of unwanted microorganisms.
In this context, lactic acid plays a particularly important role. A review published in Frontiers in Cellular and Infection Microbiology highlighted how lactic acid produced by lactobacilli is one of the main defense mechanisms of the vaginal ecosystem, contributing not only to maintaining the correct pH but also to protecting the mucosa and the overall balance of the microbiota.
Further studies conducted by O’Hanlon and colleagues confirmed that lactic acid helps create conditions favorable to the predominance of lactobacilli, supporting the maintenance of the physiological vaginal environment and the natural local defenses.
Alongside lactic acid, hyaluronic acid is widely used in formulations dedicated to the wellbeing of the vulvo-vaginal mucosa thanks to its hydrating properties and its ability to retain large amounts of water in the tissues. This characteristic helps maintain proper mucosal hydration, helping to improve elasticity, comfort, and integrity, especially in conditions associated with dryness, irritation, or local sensitivity.
The combination of lactic acid and hyaluronic acid therefore makes it possible to address two key aspects of intimate wellbeing at once: on one hand, maintaining the balance of the vaginal ecosystem and physiological pH, and on the other, supporting the hydration and function of the mucosa. For this reason, these ingredients are now widely used in formulations dedicated to intimate hygiene and vulvo-vaginal wellbeing.
