Urea, a naturally occurring compound in the skin, is widely recognized in dermatology and skin care for its hydrating and keratolytic properties. It is a component of the skin's natural moisturizing factor (NMF) and is crucial in maintaining skin hydration and barrier function.

In skin care, urea is valued for its dual action: it acts as a humectant, drawing moisture into the skin, and as a keratolytic agent, helping to break down the protein bonds between dead skin cells, leading to smoother and softer skin. This makes it particularly effective in treating dry, rough, and scaly skin conditions such as eczema, psoriasis, and ichthyosis.

Additionally, urea has been shown to have antimicrobial properties and can aid in skin barrier repair, further underscoring its utility in treating various skin conditions.

Lactic acid, a member of the alpha hydroxy acid (AHA) family, is a well-regarded ingredient in the field of dermatology and skincare for its exfoliating and moisturizing properties. Naturally occurring in sour milk and other fermented products, lactic acid is also produced in the human body and plays a role in various metabolic processes.

In skincare, lactic acid is primarily known for its ability to exfoliate the skin gently. By breaking down the bonds that hold dead skin cells together on the skin's surface, lactic acid helps to promote the shedding of these cells, revealing fresher, brighter skin underneath. This exfoliation process improves skin texture and tone and stimulates cell renewal.

One key advantage of lactic acid over other AHAs is its moisturizing capability. Lactic acid helps increase the skin's natural moisturizing factors (NMF), essential for keeping the skin hydrated. Its unique ability to draw moisture into the skin is particularly beneficial for treating dry and dehydrated skin conditions.

Glycolic acid is highly acclaimed for its remarkable exfoliating and rejuvenating properties. Its small molecular size enables deep skin penetration, fostering efficient exfoliation at the cellular level.

Glycolic acid’s water solubility allows it to penetrate the upper layers of the skin easily. Its primary mechanism of action involves weakening the bonds between dead skin cells, promoting their shedding, and revealing the newer, healthier skin beneath. This process of accelerated cell turnover is instrumental in addressing a range of skin concerns, from aging signs like fine lines and wrinkles to texture irregularities and hyperpigmentation.

Glycolic acid's efficacy extends beyond mere exfoliation. It's also recognized for stimulating collagen production, a crucial protein in maintaining skin's elasticity and firmness. This aspect contributes to its anti-aging benefits. Furthermore, its hydrating properties add to its appeal, as they help increase the skin's capacity to retain moisture, leading to a more supple and vibrant complexion.

Clinical studies have consistently supported glycolic acid's role in improving skin appearance. Research indicates significant improvements in skin texture and pigmentation and the visible reduction of wrinkles and fine lines with glycolic acid.

Emollients are crucial in dermatological care, primarily because they enhance skin hydration and barrier function. Here's a brief overview of their physiological effects and roles in managing various skin conditions.
