A star ingredient in anti-aging skincare , hyaluronic acid is renowned for its exceptional hydrating power . In both cosmetics and aesthetic medicine, this humectant promises numerous benefits: plumped skin, reduced wrinkles and fine lines, improved healing, accelerated collagen production, firmness, and volume. But what are the risks of topical application? Are the dangers of hyaluronic acid real, or are they related to misuse of the active ingredient? Nooance-Paris reveals the secrets of a safe and effective skincare routine thanks to the hydrating properties of sodium. hyaluronate .
Hyaluronic acid: is it really necessary to talk about "danger"?
According to the latest scientific studies, there are currently no known toxic risks associated with hyaluronic acid in cosmetics. This naturally occurring ingredient is reliable and well-tolerated by all skin types.
However, if used incorrectly, adverse effects may occur: redness, dehydrated or tight skin, allergic reactions… To avoid these risks, follow the advice of Nooance-Paris: this guide helps you to safely integrate hyaluronic acid into your beauty routine.
Dehydration, edema, inflammation: what are the real causes?
Hyaluronic acid injections: possible side effects
Hyaluronic acid injections, or dermal fillers, can fill deep wrinkles and also plump or restore volume to certain areas of the face (lips, cheeks, temples, cheekbones). The risks are related to the cosmetic surgery procedure itself or to poor absorption of the fillers. Complications are rare but can include: vascular embolism, local inflammation at the injection sites, serious infections, and skin necrosis.
After the injection, certain skin reactions are common: redness, tingling, bruising, edema.
In cosmetics: the risk of dehydration
Unlike hyaluronic acid injections, topical application is safe for the skin. However, dehydration can occur: here's why.
Hyaluronic acid is a hygroscopic active ingredient, capable of absorbing up to 1,000 times its weight in water and retaining it like a sponge. However, in very dry environments, it can have the opposite effect : instead of attracting water from the outside, it draws moisture from the deeper layers of the epidermis, causing surface dehydration and weakening the skin barrier.
No need to panic: Nooance-Paris guides you to use hyaluronic acid correctly, avoid undesirable effects and enjoy all the benefits of hydration on the skin.
The Nooance 3-step protocol for maximum hydration
Step 1: Always apply to damp skin
To allow hyaluronate to act effectively, it is essential to apply it to damp skin : this key step, although often forgotten, actually provides the water necessary for the active ingredient to hydrate the skin, without drawing from the deep layers of the dermis.
In practice : apply your hyaluronic acid skincare products directly after showering or after spraying a mist of thermal water on your face, making sure to maintain good hygiene conditions: clean hands and skin.
Step 2: Choosing the right formulation: the role of molecular weights
Have you ever heard of molecular weight? This criterion plays a crucial role in the effectiveness of the hyaluronic acid molecule:
- A high molecular weight remains on the surface of the skin, forming a protective film that protects the skin barrier and ensures immediate hydration.
- A low molecular weight formula provides a deeper plumping effect by working at a deeper level. Wrinkles are diminished and the skin is more elastic.
For a complete and powerful action, opt for a treatment that combines different forms of hyaluronic acids, such as the Nooance Multi-Active Serum with 5 Hyaluronic Acids .
Step 3: Seal in moisture with an oil
Even when applied to damp skin, with a good formulation, hyaluronic acid has one final drawback: it evaporates quickly. It needs an occlusive agent , such as a moisturizer or light oil, to form a waterproof film on the skin and prevent the water absorbed by the hyaluronate from evaporating.
This is THE key step to remember to optimize the hydrating effect of your serum, without side effects and with visible results: skin is more supple, bouncy and comfortable throughout the day.
