Seasonal Skincare: How to Transition Your Routine from Winter to Summer

As Australia moves from cooler months into warmer weather, your skin experiences a dramatic shift in its environment. Winter’s dry air and indoor heating often leave the skin dull and dehydrated, while summer brings humidity, heat, and higher UV exposure. Transitioning your skincare routine between these seasons is essential to maintaining balance, glow, and long-term health.

At Pt78 Skin and Body, we believe skincare should evolve with your environment. Our collection of vegan, Australian-made products complements SkinCeuticals — a world leader in clinical skincare — allowing you to adapt seamlessly between seasons while maintaining radiant, resilient skin.

Step 1: Switch to a Lightweight Cleanser

During winter, you may have relied on creamy cleansers to protect against dryness. But as humidity rises, it’s important to switch to lighter formulas that remove sweat, oil, and sunscreen without stripping the skin.

• Pt78 Foaming Cleanser — A refreshing gel that purifies and balances normal to oily skin types.

• SkinCeuticals Simply Clean Gel Cleanser — Deep cleans pores and removes impurities with a gentle exfoliating blend of amino acids and botanical extracts.

If you prefer something gentler for sensitive skin, Pt78 Cream Cleanser or SkinCeuticals Gentle Cleanser both offer soothing hydration while keeping the complexion soft and fresh.

Step 2: Refresh with an Antioxidant Boost

Environmental stressors increase significantly during warmer months, making antioxidants essential. They protect against UV damage, pollution, and free radicals that accelerate ageing and dullness.

• SkinCeuticals C E Ferulic Vitamin C Serum — The gold standard for antioxidant protection, ideal for dry or mature skin.

• SkinCeuticals Phloretin CF — A lightweight antioxidant serum perfect for combination or oily skin.

• Pt78 Highlight C 15% Vitamin C Serum — A natural, plant-based serum using Kakadu Plum and Davidson Plum to brighten and protect the skin barrier.

Morning application of Vitamin C serums helps your sunscreen work harder and gives your complexion a luminous glow.

Step 3: Lighten Your Moisturiser

In summer, heavy creams can overwhelm the skin, trapping sweat and oil. Opt for lightweight hydration that maintains barrier protection without congestion.

• Pt78 Moisture+ Hydrating Moisturiser — A clean, vegan formula rich in Rosehip and Green Tea Extracts for all-day hydration.

• SkinCeuticals Metacell Renewal B3 — Strengthens skin with Niacinamide and peptides to visibly improve elasticity.

• SkinCeuticals Emollience Moisturiser — Perfect for restoring hydration to sun-exposed or wind-stressed skin.

Those with oily or acne-prone skin may prefer Pt78 Matte+ Balancing Moisturiser — a shine-control formula that absorbs excess oil while keeping skin balanced.

Step 4: Adjust Your Active Ingredients

Retinol, AHAs, and exfoliating treatments are powerful anti-ageing tools — but they can make skin more photosensitive. Instead of stopping them completely, adjust their frequency.

• Use SkinCeuticals Retinol 0.3 or Pt78 Refine A Skin Enhancer two to three nights per week.

• On alternate nights, focus on hydration with SkinCeuticals Hydrating B5 Serum or Pt78 Brighten B Serum.

Balancing actives ensures your skin continues to renew while maintaining hydration and comfort in warmer conditions.

Step 5: Elevate Your Sun Protection

Australia’s UV index is among the highest in the world — making SPF non-negotiable. Daily use of a high-protection sunscreen prevents pigmentation, photoaging, and collagen loss.

• SkinCeuticals Ultra Facial Defense SPF 50 — Lightweight, non-comedogenic, and ideal under makeup.

• Reapply every two hours if you’re outdoors, and remember your neck and décolletage — areas often missed but prone to premature ageing.

Pair SPF with antioxidant protection for a dual-layer defence that combats both UV and free-radical damage.

Step 6: Incorporate Soothing Masks and Serums

Heat, saltwater, and air conditioning can all deplete moisture. Weekly masks and replenishing serums help restore the balance.

• SkinCeuticals Hydrating B5 Mask — Instantly replenishes skin’s moisture reserves.

• Pt78 Shine Control Serum — Helps clarify pores and maintain hydration for oily or combination skin.

• SkinCeuticals Phyto Corrective Mask — Soothes redness and reduces post-sun irritation.

These treatments are the perfect end-of-week reset to keep your skin radiant and calm through temperature changes.

The Bottom Line

As the seasons shift, your skin’s needs change — and your routine should, too. Transitioning from winter to summer is about lightening textures, boosting antioxidants, and staying consistent with sun protection.

With the right combination of SkinCeuticals’ clinical expertise and Pt78’s botanical, vegan skincare, you can maintain a balanced, glowing complexion year-round — without sacrificing comfort or sustainability.
