Ceramides are crucial components of the skin's outermost layer and play an essential role in its defense mechanism.
“Ceramide” has become a vital term in the ever-advancing skin care arena. These lipid molecules are far from just a passing trend; They play a crucial role in strengthening the skin barrier. By maintaining the skin's strength, ceramides play a vital role in protecting against environmental stressors and retaining moisture, ultimately contributing to overall skin health and resilience.
Dr Soumi Dey Sarkar, R&D group leader at Simple Skincare, Hindustan Unilever, says: “Ceramides, which are naturally found in the outermost layer of the skin, are integral components of this defense mechanism. They help maintain moisture, prevent transepidermal water loss and protect against external aggressors. However, factors such as harsh environmental conditions and skin care routines can reduce ceramide levels, compromising the integrity of the skin barrier. Additionally, he emphasizes that replenishing ceramides through skin care products can revitalize the skin barrier and promote healthier skin. “
“While there are products with ceramides, it is important to note that when applied topically, they mostly sit on the skin and cannot penetrate. The solution? Ceramide reinforcements. These are metabolized within the stratum corneum to replace lost lipids. By reinforcing the skin barrier, these products not only hydrate and nourish but also protect against irritants and contaminants,” he added.
It must be understood that ceramides are a type of lipid molecule that is naturally found in the outermost layer of the skin, known as the stratum corneum. They represent around 30-40% of the lipids in this layer and play a crucial role in maintaining the skin's barrier function. Structurally, ceramides are essential for skin cell cohesion, helping to form a protective barrier that prevents excessive water loss and protects the skin from environmental aggressors.
This barrier function is vital to keep the skin hydrated, flexible and resistant. When ceramide levels are depleted, the skin barrier is compromised, leading to increased dryness, sensitivity, and possible damage from external factors.
Harini Iyer, skin category marketing director at Plum, said: “Ceramides are like bodyguards for the skin. They work tirelessly to strengthen and repair the skin barrier. They do two main things: First, they are amazing at keeping moisture locked in. Have you ever noticed how your skin feels soft and hydrated? Thanks to the ceramides for that: they are the ones that make sure that the humidity is maintained. Secondly, they act as a shield against environmental aggressors such as pollution and toxins. Ceramides ensure that your skin stays healthy and safe from all the outside dirt.”
She added: “So next time you're looking after your skin, remember to show ceramides some love – they're the real superheroes for keeping your skin happy and healthy!”
Dr. Anupriya Goel, Medical Director of Berkowits Hair and Skin Clinics, mentions: “Ceramides are naturally present in the skin, but as we age, we begin to lose them, resulting in sagging skin, dry and dehydrated. It is an essential barrier repair ingredient in an anti-aging skin care routine. Ceramides are usually formulated as serums, creams or capsules for individual use. They can be used in both the morning and evening routine.”
While providing more information on how ceramides act as skin barriers, Rachna Rastogi, R&D Director – Skin Care, 82°E, shares: “Ceramides are naturally present in the skin and play a role crucial in maintaining skin barrier function. “These agents act as the skin’s first line of defense against external pollutants and their moisture-retention capabilities protect the skin’s natural barrier to ensure it remains soft and hydrated.” The potential of ceramides in skin care.
