FAQs
Q1. What makes Hydra-Cool Serum different from a regular hyaluronic acid serum?
A1. Standard hyaluronic acid serums hydrate and stop there. Hydra-Cool combines deep hydration with an antioxidant botanical complex that specifically addresses skin heat, redness, and inflammation — not just dryness. The cooling sensation on application isn't from fragrance; it reflects an active response to stressed skin and provides genuine calming rather than a cosmetic effect only.
Q2. Is it well-suited for Indian summer conditions — heat, humidity, and sun exposure?
A2. It's one of the better hydrating serums for hot, humid climates precisely because of its lightweight, water-based texture. It doesn't feel heavy or occlusive in heat. In summer, it can be used alone under SPF for oily skin types that don't require a separate moisturiser.
Q3. Can it be applied to sunburned or heat-stressed skin?
A3. Yes — apply to clean, slightly cooled skin after sun exposure to reduce surface heat, calm redness, and restore moisture. For added relief, refrigerate it briefly before use. Avoid applying to severely blistered or peeling sunburn without medical guidance first.
Q4. Who benefits most from this serum?
A4. Those with dry, reactive, or post-procedure skin; people recovering from a chemical peel or laser who need intensive hydration without active acids; and men experiencing post-shaving irritation. It's also the ideal first iS Clinical product for those new to the brand, as it works across all skin types with no exfoliating activity.
Q5. How do I layer it with other iS Clinical serums?
A5. Apply it after Active Serum or Pro-Heal Serum Advance+ to cushion any dryness those actives may cause. The correct order is: Active Serum → Hydra-Cool Serum → moisturiser → SPF. Hydra-Cool seals in the active ingredients rather than diluting them.
Q6. How quickly does it work?
A6. Hydration is immediately noticeable — skin feels plumper and calmer within minutes of application. For sustained improvement in moisture retention and reduced background redness, visible change appears within 2–3 weeks of consistent morning and evening use.
