Sensitive skin is one of the most misunderstood skin types in India. Many people believe they simply have "delicate" skin that cannot handle products — and they resign themselves to a lifetime of plain water and basic moisturiser, scared to try anything new.
Here is the truth: sensitive skin is rarely a permanent skin type. In most cases, it is a symptom of a damaged skin barrier and a disrupted microbiome. And it can be repaired.
What Sensitive Skin Actually Is
Sensitive skin is skin that over-reacts to stimuli that would not normally cause a reaction. Products that sting. Fabrics that irritate. Temperature changes that cause redness. Food that triggers flushing. These are all signs that your skin's natural defence and communication systems are out of calibration.
The root cause is almost always one or both of: a compromised skin barrier (the outer protective layer) or a disrupted skin microbiome (the ecosystem of bacteria that regulate your skin's immune response).
Why Most Products Make Sensitive Skin Worse
Most "sensitive skin" products are formulated by removing irritants — they take out fragrance, colour, and harsh actives. This is necessary but not sufficient. They do nothing to actively repair the barrier or rebalance the microbiome. They are like removing the thing that is hurting you without healing the wound.
Worse, many "calming" products contain alcohol, astringents, or low-concentration acids that continue to disrupt the barrier even as the packaging claims to soothe.
The Postbiotic Approach — Repair from Within
Postbiotics are the single most compatible active ingredient category for sensitive skin because they work with your skin's biology, not against it. Specifically, Lactobacillus Ferment Lysate — the postbiotic in Rub It In Serum — does the following for sensitive skin:
• Reduces the hyper-reactive inflammatory response that causes stinging, burning, and redness
• Rebalances the microbiome, restoring the bacterial populations that regulate skin's immune signalling
• Strengthens the skin barrier by supporting ceramide production — directly addressing the structural weakness that causes sensitivity
• Is pH-appropriate for skin (slightly acidic) — unlike many actives that disrupt the skin's natural pH

How to Introduce Rub It In Serum to Sensitive Skin
• Week 1: Apply every other night only — let your skin get used to any new product gradually
• Week 2: If no reaction, move to every night
• Week 3: Add morning application — you should now notice significantly reduced reactivity
• Week 4 onwards: Use morning and night consistently for ongoing barrier support
Do not combine with retinol, AHAs, or strong Vitamin C serums for the first 6 weeks. Let the postbiotic do its repair work without additional stressors.
Sensitive skin is not forever. Give it what it actually needs.
