Chemical peeling involves applying active ingredients to the skin to break down connections between corneal cells. This process cleanses the surface of dead cells and promotes new cell production. Consequently, the skin experiences reduced hyperpigmentation, acne prevention, improved radiance and smoothness, tightened pores, decreased oil secretion, and rejuvenation.

According to Doctor of First-Degree Specialization Be Thu Thuy from the Department of Aesthetics, Tam Anh General Hospital Hanoi, cold and low-humidity weather weakens the skin's protective barrier, significantly reducing its ability to retain moisture. This makes the skin prone to dryness, flaking, and irritation. During this time, incorrect application of peeling agents like AHA, BHA, TCA, or retinol can exacerbate existing dryness, leading to redness, burning, and even cracking.

For individuals with healthy skin, when chemical peels are performed correctly by a dermatology and aesthetics specialist, using appropriate concentrations and under medical supervision, they remain effective and safe. The reduced sun exposure during this period also lowers the risk of post-inflammatory hyperpigmentation, a common complication after peeling.

Mild peels, such as low-concentration AHAs (glycolic, lactic), enzyme peels, or PHAs, are preferred during dry conditions. These agents are gentle, less irritating, and suitable for beginners or those with dry, sensitive skin. Medium to deep peels with high concentrations or retinoic acid are not recommended at this time, unless specifically prescribed by a doctor. Deep peels cause significant epidermal exfoliation, leading to severe dehydration and potential damage if not properly cared for.

Even with mild peels, overuse should be avoided as skin recovery is slower compared to hot, humid seasons. Generally, peels should be done once every 2-4 weeks, depending on the type of peel and individual skin response. Those accustomed to weekly peels need to reduce the frequency or take a break to prevent thinning and weakening the skin's protective barrier.

Post-peel care is crucial for proper skin recovery during dry weather. Post-peel skin is sensitive, prone to dehydration, and requires deep hydration. Restorative creams containing ceramide, panthenol, glycerin, hyaluronic acid, squalane, or niacinamide help strengthen the moisture barrier, soothe, and reduce redness. For the first few days after peeling, avoid washing the face with hot water, limit touching the face, and do not use additional exfoliating products or those with strong active ingredients like retinoids, high-concentration vitamin C, or AHA/BHA.

Effective sun protection is essential. Post-peel skin is more susceptible to sun damage and at higher risk of hyperpigmentation if exposed directly to sunlight. Daily application of broad-spectrum sunscreen with SPF 30-50, along with protective measures like masks, glasses, and wide-brimmed hats when outdoors, helps protect the skin.

Doctor Thuy advises individuals with excessively dry, sensitive, or severely flaking skin, those with atopic dermatitis, or those using abrasive treatment products, or experiencing issues with their skin barrier, to postpone chemical peels during this period. Instead, they should opt for gentle skincare measures focused on improving skin hydration with restorative topical products or nourishing treatments such as oxygen, HA skinbooster, or mesotherapy. Chemical peels can be performed more safely and effectively once the skin's health is restored.

Those considering chemical peels during dry weather should consult a dermatology and aesthetic specialist to assess their skin condition. The doctor can then recommend the appropriate peel type, concentration, and treatment protocol, along with medical-grade aftercare instructions for healthy, smooth skin. Avoiding self-application of high-concentration products at home or undergoing peels at unreliable facilities is crucial, as this can lead to skin damage, post-peel hyperpigmentation, severe irritation, scarring, or long-term complications.
