Seasonal Skincare Adjustments Worth Making

One of the most impactful adjustments you can make is switching between lighter and heavier moisturizer formulas as conditions change. In winter, cold outdoor air and indoor heating both reduce ambient humidity, causing TEWL — the rate at which water evaporates through your skin — to increase. A richer cream with occlusive ingredients like shea butter or petrolatum can help seal moisture in.

Come summer, that same heavy cream may feel suffocating, especially in humid climates. A gel-based or water-gel moisturizer typically provides adequate hydration without contributing to congestion. The goal isn't necessarily using fewer products — it's matching the formula to what your skin barrier is actually dealing with.

If switching formulas causes unexpected reactions, common moisturizing missteps are worth reviewing before assuming the formula itself is the problem.

Foaming or gel cleansers that feel refreshing in summer heat can become strip-happy in dry winter conditions, compromising your skin barrier over time. A cream or milk cleanser — which rinses clean without aggressively removing natural oils — is often a gentler choice when the air is cold and dry.

Conversely, if you're prone to excess oil in warm weather, a slightly more clarifying formula used once a day (typically in the evening) can help keep pores clear without over-drying. The key word is balance: cleansing should remove debris and sunscreen effectively, not leave your skin feeling tight or squeaky.

Exfoliation — whether chemical (like AHAs or BHAs) or physical (scrubs) — helps clear away dead skin cells and can support a smoother texture. But frequency matters as much as the method, and seasonal changes are a good time to reassess.

In winter, skin often becomes more sensitive and reactive due to barrier disruption from cold and wind. Dialing back exfoliation to once or twice a week (rather than daily or near-daily) can reduce the risk of irritation. In humid summer months, some people find they tolerate slightly more frequent exfoliation without issue — but this is highly individual and worth introducing gradually.

If you're using active ingredients like retinoids alongside exfoliants, be especially cautious during seasonal transitions when skin sensitivity tends to peak. A dermatologist is the right resource if you're unsure how to combine actives safely.

Sunscreen is genuinely non-negotiable in every season. UV radiation — particularly UVA rays, which penetrate clouds and glass — reaches your skin year-round, not just on summer beach days. Why dermatologists treat SPF as non-negotiable goes deeper into the science if you want the full picture.

What can reasonably change with the seasons is the sunscreen formula. A lightweight fluid or serum-based SPF may work beautifully in summer, while a creamier SPF formula can double as added moisturization in winter without requiring an extra layer. Some people also find that mineral formulas sit more comfortably under winter base makeup, while chemical formulas integrate better under sunscreen-challenged summer skin. Experiment to find what actually gets applied consistently — application consistency matters more than formula perfection.

Hyaluronic acid is widely praised for its humectant properties — it draws moisture toward the skin. The catch is that it draws moisture from the nearest available source, which in very low-humidity environments (like a heated apartment in February) can actually be your own skin rather than the air.

In dry conditions, applying a hyaluronic acid serum and sealing it immediately with a moisturizer minimizes this risk. Skipping the sealing step in dry winter air may leave skin feeling drier than before. In humid summer air, hyaluronic acid tends to perform as expected with less risk of moisture pull.

This is one reason why product layering order matters — particularly during seasonal transitions when environmental conditions change how individual ingredients behave on your skin.

For a broader check on how your whole routine is functioning across seasons, a routine audit can help you identify gaps without starting from scratch.
