What is hyaluronic acid?

Hyaluronic acid's main function is to hydrate and protect the skin from external damage. Its water-retaining capabilities provide deep and lasting hydration, resulting in smooth and radiant skin. This is why hyaluronic acid is often called the "cement of the skin."

It is a molecule naturally present in the human body, crucial for maintaining skin hydration, suppleness, and youthfulness. You can find it in various products, from moisturising creams to serums, and even in nutricosmetic supplements.

The benefits of hyaluronic acid for the skin

• Deep hydration: Hyaluronic acid can retain water up to 1000 times its weight, providing intense hydration. This improves the skin's texture, making it softer, smoother, and visibly hydrated.
• Anti-ageing: By filling in the spaces between skin cells, hyaluronic acid reduces the appearance of wrinkles and fine lines. It also enhances skin firmness and elasticity, fighting the visible signs of ageing.
• Suitable for all skin types: Hyaluronic acid is compatible with all skin types. Whether your skin is dry, oily, sensitive, or combination, it provides essential hydration without causing irritation or adverse reactions.

How to incorporate hyaluronic acid into your skincare routine

• Choosing the right product: Opt for a high-quality serum or cream with hyaluronic acid. Serums are great for deep penetration, while creams are ideal for surface hydration. Tip: Apply your serum before your cream to enhance the absorption of hydrating agents.
• Dietary supplements: Hyaluronic acid supplements can also help hydrate your skin from within, providing additional benefits for your overall health.

How long does it take to see the effects of hyaluronic acid?

Results can vary, but many people notice improved hydration and fewer wrinkles after a few weeks of regular use.

Is hyaluronic acid safe for all skin types?

Hyaluronic acid can be safely combined with other active ingredients like vitamin C, retinoids, and AHA/BHA. This can boost anti-ageing effects and contribute to a radiant, healthy complexion. Try our hyaluronic acid course enriched with vitamin C to enhance collagen synthesis in your skin.

Side effects of hyaluronic acid

Hyaluronic acid is generally well-tolerated, but side effects can vary based on usage:

• Injections: May cause redness, swelling, pain, bruising, and rarely, infections or granulomas at the injection site.
• Topical use: Generally safe, but sensitive skin may react.
• Supplements: Usually well-tolerated, but can occasionally cause mild bloating.

Always consult your doctor before starting any hyaluronic acid treatment, especially if you have pre-existing conditions or are taking other medications.

The origin of hyaluronic acid

Hyaluronic acid was discovered over 80 years ago in the vitreous humour of a cow's eye, a gelatinous substance that fills the space between the lens and the retina. Composed mainly of water, collagen, and hyaluronic acid, it maintains the eye's shape and allows light to pass to the retina without distortion.

This substance was later isolated by two German researchers, Meyer and Palmer, who found that this molecule is naturally present in the human body and is a key component of the skin's dermis (the layer between the epidermis and the hypodermis).
