The history of skincare shows a fascinating shift: from simply covering imperfections to today’s science-driven approach focused on treatment and prevention.

In the past, when skin issues appeared, people relied on concealing them. Long sleeves, gloves, scarves, and heavy makeup were used not to heal but to mask imperfections.

Today, dermatology and cosmetics emphasize repair and protection. Modern products aim not only to improve appearance but also to strengthen skin health on a cellular level—hydrating, nourishing, shielding against UV rays and pollution, and helping slow down premature aging.

This evolution from concealment to real care has allowed people to better understand their skin and choose products tailored to its needs.

What ingredients are essential for very dry and atopic skin?

The priority is to select formulations that both hydrate and restore the skin barrier. In Cerafavit LIBREDERM products, three star ingredients do exactly that: ceramides, vitamin F, and prebiotics.

Ceramides — the building blocks of the skin barrier

Ceramides are natural lipids in the epidermis that act like “cement,” sealing skin cells together. They:

• lock in moisture and prevent dehydration;
• protect against external aggressors;
• improve elasticity, softness, and smoothness.

With age and environmental stress, ceramide levels decline, leading to dryness and sensitivity. Skincare enriched with ceramides replenishes this deficit, restoring hydration and resilience.

Vitamin F — nourishment and repair

Vitamin F is the collective name for two essential fatty acids (omega-3 and omega-6) that the body cannot produce on its own. They reinforce the skin’s lipid barrier, improve hydration, and reduce inflammation. Sources include diet (nuts, flaxseed oil, fish oil) and skincare products.

Prebiotics — guardians of the microbiome

Prebiotics nourish beneficial microorganisms on the skin’s surface, supporting a balanced microbiome. This strengthens the natural defense system, helping to reduce redness, irritation, and flare-ups common in atopic skin.

The synergy of three key components

When combined, ceramides, vitamin F, and prebiotics deliver deep hydration, barrier repair, and microbiome support. The result is calm, supple, and resilient skin—free from the tightness, flakiness, and discomfort typical of very dry and atopic conditions.
