Summer Skincare

Summer means heat, humidity, sweat, and increased UV exposure. Your skin's needs change: oil production increases, sunscreen becomes non-negotiable, and lightweight textures feel better. The three pillars of summer skincare are: SPF protection, lightweight hydration, and gentle cleansing.

• SPF 50+ broad-spectrum, applied generously and reapplied every 2 hours. • Water-resistant formulas if you swim or sweat. • Mineral sunscreens (zinc oxide) are less likely to sting eyes when sweating. • Don't forget ears, back of neck, tops of feet, and lips. • UV index is highest 10am–4pm — seek shade during these hours.

Swap heavy creams for gel or water-based moisturisers. Look for: • Hyaluronic acid — lightweight hydration. • Glycerin — humectant that works in humidity. • Niacinamide — regulates oil production. • Avoid heavy oils (coconut, shea) that can clog pores in humid weather.

• Increased sweat and oil can lead to clogged pores — gentle exfoliation helps. • BHA (salicylic acid) is ideal for oily summer skin. • AHA can increase photosensitivity — use at night only and SPF diligently the next day. • Reduce exfoliation frequency if you're spending a lot of time in the sun.

AM: Water rinse or gentle cleanser → Vitamin C serum → Gel moisturiser → SPF 50+ PM: Oil cleanser → Gentle foaming cleanser → BHA (3x/week) → Niacinamide serum → Light moisturiser Weekly: Clay mask for oil control (1x/week)

The biggest gap in most people's sun protection strategy is reapplication. Even SPF 50 provides no protection after 2 hours of direct sun exposure. The reapplication challenge: Most people apply sunscreen in the morning and consider themselves protected all day. This is inadequate. SPF effectiveness degrades through UV exposure itself (photodegradation), sweating, sebum, and physical contact. Practical reapplication methods for daily wear: • SPF Setting Spray: Products like Coola Mineral Sun Silk Drops or Australian Gold Botanical SPF 50 can be spritzed over makeup without disturbing it. • SPF Powder: Brush-on SPF powder (e.g., Colorescience Sunforgettable) allows reapplication over makeup. Most offer SPF 30–50. • Reapply after swimming: Water resistance is rated for 40 or 80 minutes of water exposure — reapply immediately after towelling dry. • Reapply after heavy sweating: If exercising outdoors, reapply every 60–90 minutes. The 1/4 teaspoon rule: Most people apply 20–50% of the required amount. A 1/4 teaspoon = 1.25mL is the evidence-based amount for face and neck. This is significantly more than most people apply. Sun protective clothing: For prolonged outdoor time, UPF-rated clothing (50+ = blocks 98% UV) is more reliable than sunscreen for covered areas. A wide-brim hat (minimum 3-inch brim) dramatically reduces facial sun exposure.

Summer creates specific skin challenges beyond typical breakouts. Heat rash (miliaria): Caused by blocked sweat glands, not bacteria or sebum. Appears as tiny, itchy red bumps or clear blisters, typically on the chest, back, and neck. Treat with gentle BHA (salicylic acid) to unblock glands, lightweight non-comedogenic moisturiser, and cool showers. Avoid heavy sunscreens or thick products on affected areas — switch to mineral spray SPF. Comedonal summer acne: Sweat mixed with sunscreen and sebum creates a film that blocks pores. Prevention: use oil-free, non-comedogenic SPF. Cleanse as soon as possible after heavy sweating. Use BHA 2–3x/week. Perioral dermatitis flare in summer: Heat and SPF occlusion around the mouth can trigger perioral dermatitis (red bumpy rash around nose and mouth). If this occurs, stop all heavy creams around the mouth, avoid fluoride toothpaste (controversial but often implicated), and see a dermatologist — topical metronidazole or azelaic acid is typically prescribed. Post-sun hyperpigmentation: UV triggers melanin production. Existing pigmented spots deepen in summer. Counter-strategy: SPF 50+ every day, vitamin C in AM, niacinamide in PM, and avoid picking at any post-acne marks which are more reactive to UV.
