Lard

Lard is a rendered fat obtained from porcine (pig) tissue. In skincare, it appears both in its unmodified form and as derivatives such as lard glycerides and hydrogenated lard glycerides, which are created through controlled chemical processing.These ingredients function primarily as skin-conditioning agents, helping to soften and smooth the skin surface. The hydrogenated derivatives also serve as viscosity-increasing agents, thickening formulations to achieve the desired texture and consistency.

Lard comprises triglycerides (three fatty acids linked to a glycerol backbone). When applied to skin, these triglycerides sit on the surface, creating an occlusive barrier that traps moisture and prevents water evaporation. This mechanism is similar to other occlusive oils and butters.The hydrogenated forms undergo controlled saturation of their fatty acids, making them more stable and solid at room temperature. This altered structure allows them to thicken formulations whilst maintaining the same occlusive skin-conditioning function.

Lard-containing products are typically used as part of a moisturising routine, applied to clean skin. Concentration and frequency depend on the specific formulation and your skin's needs. Start with small amounts and adjust based on how your skin responds, particularly if you have oily or acne-prone skin, as occlusive ingredients can sometimes trigger congestion in sensitive individuals.

Lard and its derivatives are generally well-tolerated and established as safe in cosmetic use. Some individuals with acne-prone or fungal-acne-sensitive skin may find occlusive animal fats trigger congestion; patch testing is advisable if you have a history of sensitivity.
