Hyaluronic Acid (HA) is a polysaccharide chain naturally present throughout the human body. In fact, the organ with the highest concentration of Hyaluronic Acid in the body is the skin. Hyaluronic Acid is a powerful natural humectant that can draw water into the skin, helping it look firmer and plumper. 1g of Hyaluronic Acid can hold 1000 times its weight in water, so it's no exaggeration to call Hyaluronic Acid the skin's natural "water reservoir."

As we age, the amount of Hyaluronic Acid produced by the skin also decreases. Meanwhile, this natural humectant is responsible for maintaining moisture in the skin, nourishing the extracellular matrix (ECM), and improving the skin's firm, plump, and smooth appearance. Hyaluronic Acid begins to decline in the 20s, leading to the formation of fine lines, wrinkles, and dull skin. From the age of 40-50 onwards, signs of aging become more prominent with deeper wrinkles, sagging skin, and a rough and uneven skin texture.

Understanding the important role of Hyaluronic Acid for the skin, the cosmetic brand oh!oh! (Korea) – specializing in beauty and skin health solutions – has launched the oh!oh! HA serum amber, which helps replenish depleted Hyaluronic Acid in the skin, thereby providing deep hydration and addressing signs of aging as natural Hyaluronic Acid levels decline, while also stimulating the extracellular matrix in the dermis.

While many products on the market only deliver Hyaluronic Acid to the skin's surface, the oh!oh! HA serum amber stands out by containing three types of Hyaluronic Acid with three different molecular sizes, capable of penetrating deep into the skin's layers to provide long-lasting moisture and effectively improve dry, rough skin. In addition, the product offers many other excellent benefits thanks to its multi-functional formula – supplemented with skin-brightening Niacinamide, skin-restoring Panthenol, and soothing, anti-irritant Allantoin.

1% Hyaluronic Acid

The product formula contains three types of Hyaluronic Acid with different molecular sizes: Macromolecular Hyaluronic Acid, Small Molecule Hyaluronic Acid, and Micromolecular Hyaluronic Acid. The combination of these three types of HA provides optimal absorption into the skin, delivering moisture to each skin layer from outside in, top down, thereby providing comprehensive and long-lasting skin hydration.

• Macromolecular HA: locks in moisture on the surface, preventing skin dehydration.

• Small Molecule HA: transports water and moisture through the inner skin layers.

• Micromolecular HA: provides deep hydration to the lower skin layers.

Specifically, Hyaluronic Acid plays a crucial role in amplifying skin moisture and hydration. When the overall Hyaluronic Acid content in the skin increases, it creates an ideal environment for collagen to thrive, thereby strengthening the skin's foundational structure – the extracellular matrix – helping to support a firm and smooth skin structure and prevent external aggressors from damaging and aging the skin.

With its trio of exceptional Hyaluronic Acids, oh!oh! HA serum amber helps restore the skin's plumpness, elasticity, and firmness, and helps reduce the appearance of crow's feet, nasolabial folds, and marionette lines.

2% Niacinamide

Niacinamide (Nicotinamide) is a water-soluble derivative of vitamin B3 with many benefits for the skin, such as: anti-inflammatory properties, soothing redness and irritation, brightening the skin and improving uneven skin tone, reducing excess oil, and helping to minimize pores. In addition, Niacinamide can strengthen the skin's protective barrier (the skin's first line of defense) without causing sensitivity or irritation like retinol, thereby reducing the negative effects of the environment, and also playing an important role in helping the skin recover from existing signs of damage. If left unchecked, these daily aggressions will cause the skin to age, become dull, and lose its radiance.

Additionally, Niacinamide also acts as an antioxidant by limiting free radical damage. Furthermore, Niacinamide enhances hydration, helping to retain moisture in the skin, preventing transepidermal water loss, and simultaneously boosting the effectiveness of other moisturizing ingredients.

Niacinamide is easily compatible with all skincare ingredients, including Hyaluronic Acid. Niacinamide is very gentle, suitable even for sensitive skin and skin with rosacea.

Panthenol (Vitamin B5)

Panthenol (pro-vitamin B5) is an alcohol derivative of vitamin B5. When applied to the skin, Panthenol is quickly absorbed and converted into vitamin B5, which acts as a moisturizing ingredient to keep skin hydrated and prevent flaking. Panthenol is versatile; it not only helps retain and bind moisture but also supports other moisturizing ingredients, such as Hyaluronic Acid.

In its role as a humectant, Panthenol helps attract moisture into the skin and retain essential water, allowing the skin to generate its own moisture and hydration from within. This mechanism is similar to other familiar humectants like Hyaluronic Acid or Glycerin. Additionally, by forming a protective film on the skin, Panthenol helps reduce the risk of water loss and dryness due to evaporation and prevents natural water loss over time.

In addition, Panthenol's natural moisturizing properties contribute to its anti-inflammatory characteristics. Research has shown that Panthenol is effective against irritation and redness caused by UV exposure. Panthenol acts as a skin protectant that helps reduce itching and irritation from external stimuli. This ingredient can also soothe the skin by attracting water.

Finally, Panthenol can help heal wounds thanks to its ability to restore and improve skin and skin texture, making it smoother.

Lightweight texture, fast-absorbing, non-greasy

The outstanding advantage of oh!oh! HA serum amber lies in its lightweight, fluid serum texture that absorbs quickly into the skin immediately after application. Thanks to its formula rich in water-soluble moisturizing ingredients (Hyaluronic Acid, Niacinamide, Panthenol), the product provides powerful and long-lasting hydration to the skin while remaining lightweight, non-greasy, and non-comedogenic. Therefore, it can be used by all skin types, including oily and acne-prone skin.

Summary

Not only is it an ideal choice for moisturizing and hydrating dry skin, the oh!oh! HA serum amber also promises to be a powerful ally for those seeking a long-term anti-aging solution, helping to minimize the negative effects of UV rays and environmental factors on the skin, contributing to a strong and stable skin barrier.
