Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan found throughout the body's connective, epithelial, and neural tissues. Most abundantly present in the skin, eyes, and synovial fluid, HA is renowned for its exceptional capacity to retain moisture — a single gram can hold up to six liters of water.

In skincare, the primary appeal of hyaluronic acid lies in its unparalleled hydrating abilities. As a humectant, HA attracts and retains moisture from the environment, providing intense hydration to the skin. This hydrating property contributes significantly to maintaining skin plumpness, suppleness, and elasticity.

Beyond hydration, hyaluronic acid also plays a vital role in skin repair and regeneration. It supports the skin's healing and repair processes, and its anti-inflammatory properties help calm irritated skin. Moreover, HA's ability to promote collagen production, a crucial protein for skin elasticity, further underscores its anti-aging benefits.

The molecular size of hyaluronic acid influences its skin penetration and efficacy. High-molecular-weight HA remains on the skin's surface, providing hydration and forming a barrier against moisture loss. In contrast, low-molecular-weight HA penetrates deeper into the skin's layers, offering more profound hydrating and rejuvenating effects.

Hyaluronic acid's remarkable ability to hydrate, improve skin elasticity, aid in wound healing, and provide antioxidant protection makes it valuable in managing various dermatological conditions, particularly aging, dryness, and sensitive skin.

Niacinamide offers several benefits for the skin, primarily due to its anti-inflammatory and antioxidant properties. It reduces the redness and inflammation associated with acne, rosacea, and other inflammatory skin conditions. Additionally, niacinamide's ability to improve the skin's barrier function benefits all skin types, particularly those with eczema or mature skin.

Another significant benefit of niacinamide is its role in reducing hyperpigmentation. Studies have shown that it can decrease the transfer of melanin to the epidermis, helping to fade dark spots and even out skin tone.

Niacinamide also plays a role in reducing the visible signs of aging. It has been found to stimulate collagen production and improve skin elasticity, reducing fine lines and wrinkles. Its antioxidant properties further protect the skin from environmental damage, such as pollution and UV radiation, which contribute to premature aging.

The efficacy of niacinamide and its ability to address multiple skin concerns simultaneously has led to its growing popularity in both over-the-counter and prescription skincare formulations.

• Barrier Function Enhancement: Niacinamide helps strengthen the skin’s barrier function by increasing the production of ceramides, lipids that keep the skin hydrated and protect against environmental damage.
• Anti-inflammatory Properties: It has notable anti-inflammatory effects, which are beneficial in reducing redness and inflammation associated with acne, eczema, and other inflammatory skin conditions.
• Sebum Regulation: Niacinamide helps regulate sebum production, which controls excess oiliness and can benefit acne-prone skin.
