Autumn & Winter Moisturizing: Beating Seasonal Dry Skin

This is an English adaptation of a clinical article Dr. SangYoul Yun — board-certified dermatologist and Medical Director of Delight Dermatology in Gangnam, Seoul — originally published in Korean. Read the Korean original on Naver. It has been restructured and translated for international readers.

As autumn settles in and the mornings turn crisp, skin that spent the summer sweaty and oily starts to feel increasingly dry. It becomes dry and rough, and the surface can begin to scale and peel. So why does the face lose water and become dry in the first place?

How the skin barrier holds water

The skin barrier contains lipids and natural moisturizing factor (NMF).

• An adequate amount of lipid builds a protective barrier that holds water in the skin. When lipids run low, skin becomes dry and tight.
• NMF draws water in and binds it to the stratum corneum and the upper skin layers. When NMF is deficient, dryness also develops.

Four causes of dry skin

1. External environment. Dryness develops as autumn and winter humidity drops.
2. Improper cleansing. Washing once a day to remove sebum is fine, but washing too often or scrubbing hard damages the skin barrier and triggers dryness.
3. UV exposure. The ever-present culprit — UV accelerates water evaporation from the skin, causing dryness.
4. Other factors. Aging, atopic dermatitis, psoriasis, diabetes, and medications such as diuretics can all contribute.

How to manage seasonal dryness

1. Adjust daily habits

• Cut down on time spent outdoors in the cold.
• When heating indoors, run a humidifier to avoid dry air.
• Take quick, lukewarm showers rather than hot ones.

2. Replenish water

During dry seasons, drink enough water to keep the body hydrated from within.

3. Moisturize

Apply moisturizer frequently to prevent the skin from drying out. If you produce a lot of sebum, choose a formulation that holds water rather than one heavy in oils.

4. Hydrating "glow" injections

This is a treatment that injects hyaluronic acid (HA) directly into the skin. It offers antioxidant benefits along with hydration, brightening, firmness and improvement of fine lines. The procedure is short and simple, so it's easy to have done. Because it uses HA — a substance that already exists in the skin — allergic reactions and inflammation are uncommon. It can be delivered by hand injection or with a Dermashine device (which tends to be less painful). HA is biodegradable, so it is naturally resorbed over time. I generally recommend about three sessions at one-month intervals. Small raised bumps ("embossing") may appear afterward but usually fade within 3–5 days.

The single most important thing for beating autumn and winter dryness is, first and second, moisturizing. Hydrating injections such as HA "glow" injections belong to our skin booster family, and consistent daily care sits at the heart of any good skin-care routine. If simple moisturizing isn't enough to overcome the dryness, I'd recommend seeing a dermatologist for moisturizing treatment.
