Dermatologist Denise Ozores explains how festive sugar and alcohol intake damage collagen and accelerate skin aging.
The period between Christmas and New Year’s often leaves marks that go beyond body weight. Rich meals and increased sugar and alcohol intake directly affect the skin. The main cause is glycation, a biochemical process intensified by excess sugar in the body that speeds up skin aging.
During the holidays, blood sugar spikes encourage the formation of AGEs, molecules that bind to collagen fibers and alter their structure. The result is less flexible and less efficient collagen, leading to skin with reduced firmness and radiance.
Dermatologist Dr. Denise Ozores (CRM SP 101677 | RQE 7349), an expert in natural beauty and collagen stimulation, points out: “When sugar binds to collagen, the fiber loses elasticity, making the skin less firm and uniform.”
Alcohol worsens the effect. In addition to increasing inflammation, it disrupts sleep quality—vital for skin regeneration. “Deep sleep is when the body produces the most collagen. When sleep is reduced, the skin looks noticeably tired,” says Ozores.
Understanding this process, according to her, helps people maintain balance without giving up festive enjoyment. “The skin has a kind of metabolic memory. Small, repeated excesses over time directly influence how it ages,” she explains.
As January arrives, skin recovery can be supported with proper hydration, antioxidants, and regular sleep. Still, the dermatologist emphasizes prevention: “Protecting collagen before the holidays and moderating sugar consumption make a real difference in firmness and glow, maintaining lasting beauty.”
