 Ceramides are crucial components of the skin’s outermost layer, playing an essential role in its defence mechanism.

“Ceramides” have emerged as a pivotal term in the continually advancing realm of skincare. These lipid molecules are far from being merely a fleeting trend; they serve a crucial function in fortifying 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, Group Lead R&D at Simple Skincare, Hindustan Unilever, says, “Ceramides, naturally occurring in the skin’s outermost layer, are integral components of this defence mechanism. They help maintain moisture, prevent trans-epidermal water loss, and shield against external aggressors. However, factors like harsh environmental conditions and skincare routines can deplete ceramide levels, compromising the skin barrier’s integrity. She further emphasizes that replenishing ceramides through skincare products can revitalize the skin barrier, promoting healthier skin.  ”

“While there are products with Ceramides, it is important to note when applied topically, they mostly sit on top of the skin and cannot penetrate. The solution? Ceramide Boosters. These metabolize within the Stratum Corneum to replenish lost lipids. By reinforcing the skin barrier, these products not only hydrate and nourish but also shield against irritants and pollutants,” she further added.

One has to understand that ceramides are a type of lipid molecule that naturally occurs in the outermost layer of the skin, known as the stratum corneum. They account for about 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 the cohesion of skin cells, which helps form a protective barrier that prevents excessive water loss and shields the skin from environmental aggressors.

This barrier function is vital for keeping the skin hydrated, supple, and resilient. When ceramide levels are depleted, the skin barrier becomes compromised, leading to increased dryness, sensitivity, and potential damage from external factors.

Harini Iyer, Marketing Manager – Skin Category at Plum, pointed out, “Ceramides are like bodyguards for your skin. They work tirelessly to strengthen and repair your skin barrier. They do two main things: First, they’re awesome at keeping moisture locked in. Ever notice how your skin feels soft and hydrated? Thank ceramides for that – they’re the ones making sure the moisture stays put. Second, they act as a shield against environmental aggressors like pollution and toxins. Ceramides make sure your skin stays safe and sound from all the outside gunk.”

She went on to add, “So, next time you’re taking care of your skin, remember to show some love to ceramides – they’re the real superheroes in keeping your skin happy and healthy!”

Dr. Anupriya Goel- Medical Director, Berkowits Hair and skin Clinics, mentions, “Ceramides are naturally present in the skin, but as we age, we begin to lose them which results in sagging, dry and dehydrated skin. It is a barrier repair ingredient which is essential in an anti-ageing skincare routine. Ceramides are usually formulated as serums, creams or individual-use capsules. They can be used both in your morning and evening routine.”

While providing more insight into how ceramides act as skin barriers, Rachna Rastogi, Head R&D – Skincare, 82°E shares, “Ceramides are naturally present in the skin and play a crucial role in maintaining the skin barrier function. These agents act as the skin’s first line of defence against external pollutants, and their moisture-retaining capacity protects the skin’s natural barrier to ensure it stays smooth and hydrated.”ve potential of ceramides in skincare.
