HYALURONIC
ACID SERUM

Hyaluronic acid is a natural humectant composed of disaccharide chains (sugar) found in every tissue of the human body. It is present in high concentrations within the skin and the fluids around the eyes and joints. As the body's natural hydrator, this hydrophilic (water-loving) molecule acts like a sponge to attract and retain 1,000 times its own weight in water, making it an excellent moisturiser when applied topically.

Hyaluronic acid improves texture and plumps the appearance of skin. In the other parts of the body, it can reduce joint pain and other various symptoms often associated with ageing. It is a naturally occurring molecule in the human body and is found in the largest amounts between skin cells, inside joints, within the eye sockets, and in other tissues where it can help retain collagen, increase moisture, and provide elasticity and flexibility.

While hyaluronic acid is present throughout the body, 50% is concentrated within skin tissue, notably in the surface layers, where it attracts water, as well as the dermal layers, where it acts like a scaffold for essential proteins such as collagen and elastin. This molecule however has a short lifecycle in skin, with 30-50% degrading every 24 hours. With age, the skin experiences a gradual decline in hyaluronic acid levels. Production starts to decrease in the 20s and accelerates in the 40s. The combined decline and rapid natural degradation of hyaluronic acid contribute to signs of ageing including dryness, fine lines and wrinkles, uneven skin texture, loss of firmness, and loss of facial fullness.

One of the hallmarks of ageing skin is loss of moisture, resulting in decreased firmness, plumpness, and elasticity. Hyaluronic acid is a fundamental molecule involved in maintaining skin's moisture content due to its unique capability to attract and retain water. Thus, topical application of hyaluronic acid can deliver long-lasting hydration while helping skin look and feel smoother, firmer, and appear plumper.

Hyaluronic acid is an ideal ingredient for all skin types because of its oil-free, hydrating properties. It is naturally found in skin and hydrates without sensitisation or an oily feel. While all SkinCeuticals hyaluronic acid serums deliver long-lasting hydration, they are available in a variety of formulations that can also address specific skin concerns, such as fine lines and wrinkles, discolouration, sensitivity, dehydration, and imperfections. Look for a hyaluronic acid formula that addresses your specific skin concern.

When it comes to oily skin, it may seem like a good idea to avoid hydration for fear of clogging pores. However, the opposite is true. Depleting skin of essential moisture can cause it to overcompensate and produce even more oil. However, many traditional hydrating ingredients can feel tacky or heavy on oily skin. As a result, it is important to look for oil free, non comedogenic formulas that help retain moisture levels in skin.

Recognized as the body’s natural moisturiser, hyaluronic acid is capable of retaining 1,000x its weight in water. Featured in SkinCeuticals  Hydrating B5, this lightweight moisturising agent has a unique ability to attract and retain moisture in skin, effectively delivering long-lasting hydration without clogging pores.

Yes! As you begin to age, the hyaluronic acid found in the body begins to slowly diminish or lose its function, contributing to  dryness,  fine lines and wrinkles, rough patches, and a loss of firmness. Depending on the serum and your skin type, hyaluronic acid serums can provide a multitude of benefits to the skin. Adding a hyaluronic acid serum to your daily skincare regimen will not only provide hydration to the skin, but can also help improve skin texture and give skin a more plump appearance.

SkinCeuticals Hyaluronic Acid Intensifier  is formulated with high concentrations of pure hyaluronic acid and is proven to amplify skin’s hyaluronic acid levels, improve skin’s texture, and provide long lasting hydration.

Serums containing hyaluronic acid should be applied once or twice daily for optimal hydration, unless otherwise stated. If using in the morning, apply after  a SkinCeuticals vitamin C antioxidant serum  and before a  SkinCeuticals sunscreen. If using a  retinol  at night, be sure to apply the hyaluronic acid serum after your retinol application. If you are unsure of how or when to apply your hyaluronic acid serum, consult a  skincare professional.
