The hydrolipidic film is a cornerstone of skin health, yet it's frequently misunderstood, resulting in ineffective skincare routines and common skin concerns. Drawing from years of dermatological expertise at Veld's, here's a comprehensive guide to this essential skin ally.
To grasp the hydrolipidic film, consider the skin's layered structure. The outermost layer, the epidermis, includes the stratum corneum—the surface you touch. This barrier isn't directly exposed; it's shielded by the invisible hydrolipidic film, which enables its protective role. Present across the body, this film renews continuously to maintain efficacy.
This film is indispensable for skin vitality. It sustains an acidic pH (4.2–6.7) on the skin's surface—far from neutral—to block harmful microorganisms like bacteria and pathogens.
It also combats dehydration with low permeability, preserving optimal hydration in the stratum corneum. It regulates water diffusion from deeper tissues and limits evaporation from environmental factors like heat and wind.
Composed of water (hydro) and lipids (fats), the aqueous phase—from sweat and internal skin moisture—creates the acidic pH. The lipid phase, from sebum produced by sebaceous glands, locks in moisture.
These phases form a delicate emulsion. Disruptions from aging, harsh products, or poor diet can imbalance it, impairing function and influencing skin type: excess oil leads to oily skin, while lipid deficiency causes dryness.
Maintaining this film is key to radiant skin. Avoid damage and support recovery with targeted skincare.
Aggressive foaming cleansers strip vital lipids, weakening the barrier. Choose gentle cleansing oils instead to cleanse without compromise.
Daily moisturizing replenishes the film's water needs, preventing dehydration rather than just adding moisture. Our Age2O moisturizing cream delivers hydrating and anti-aging benefits. For dehydrated skin, layer a quenching serum underneath, and use a hyaluronic acid mask weekly or as needed.
