India has one of the most demanding climates in the world for skin. Summer brings UV indices of 10–11, temperatures above 40°C, and humidity levels that make every product feel heavy. Then the monsoon arrives with 90%+ humidity, mould spores in the air, sudden temperature drops, and skin that cannot decide whether it is oily, dry, or both simultaneously.
Most global skincare advice is designed for temperate climates with mild seasonal variation. It does not account for what Indian skin goes through. This guide does.
Summer Skincare — What Changes and Why
In summer, the primary skin challenges are:
• UV damage: UV index 10–11 means serious melanin stimulation and barrier damage within 15 minutes of unprotected exposure
• Excess sebum: Heat activates sebaceous glands, causing overproduction of oil
• Sweat and microbiome disruption: Sweat changes the pH of your skin, which disrupts the microbial ecosystem and can trigger acne and irritation
• Pollution: Summer heat increases particulate matter in the air, which penetrates the barrier and causes oxidative damage
Summer Routine Adjustments
• Switch to a lightweight gel moisturiser instead of a cream — your serum provides hydration, your moisturiser should just seal it in
• SPF 50 is non-negotiable in summer — reapply every 2–3 hours if outdoors
• Do not over-cleanse in response to oiliness — wash maximum twice a day with a gentle cleanser
• Keep Rub It In Serum in your routine year-round — the postbiotic keeps the microbiome balanced even as sweat and heat disrupt it
Monsoon Skincare — The Hidden Skin Challenges
Monsoon is underestimated as a skin stressor. High humidity means skin stays moist longer — which sounds good but actually creates conditions for fungal growth on skin and dramatically increases the risk of folliculitis (infected hair follicles that look like tiny pimples). The sudden temperature variation between air-conditioned spaces and humid outdoors also repeatedly shocks the barrier.
• Fungal acne (pityrosporum folliculitis): Looks like small uniform bumps on the forehead and cheeks. Extremely common in Indian monsoon. Is NOT bacterial acne and does not respond to anti-acne products. A balanced microbiome is the best prevention.
• Increased sensitivity: The barrier is under stress from humidity fluctuation — the postbiotic serum is especially valuable during monsoon for its barrier-strengthening properties
• Congested pores: Humidity + pollution = pore congestion. Gentle chemical exfoliation (AHA/BHA) 1–2 times per week prevents buildup
What Stays Constant Regardless of Season
The core of your routine does not change with the seasons:
• Gentle cleanser — always
• Rub It In Postbiotic Serum — morning and night, year-round — this is your microbiome anchor across every season
• Moisturiser — the texture changes (lighter in summer, richer in winter) but hydration is always necessary
• SPF — every single morning, rain or shine, summer or monsoon
Your serum is your constant. Everything else is seasonal adaptation.
