Name: Photo Defense Gel Sunscreen
Brand: SkinQ Rx

Indication

Broad-spectrum photoprotection against UVB, UVA, blue light (HEV), and infrared. Mandatory AM step in all 5 SkinQ Rx protocols — Hydration, Pigmentation, Acne, Sunscreen, pH Balance. Also indicated post-procedure (laser, peel, microneedling) where compromised barrier has zero UV defence. Validated for Indian climate, gel texture, non-greasy, non-comedogenic.

Composition

UV Filter System (Hybrid)

Filter	Type	Spectrum	Function
Tinosorb M	Hybrid organic-inorganic	UVB + UVA	Absorption + reflection; superior photostability
Tinosorb S	Organic photostable	UVB + UVA	Wide spectral range; no free radicals
Zinc Oxide	Mineral physical blocker	UVA + UVB	Surface reflection; intrinsically photostable
Titanium Dioxide	Mineral micronised	UVB	Reflects/scatters; zero white cast on Fitz III–VI
Uvinal A Plus	BASF organic	UVA-I	Targets deepest UVA — DNA damage and photoaging
Uvinal T 150	Ethylhexyl Triazone	UVB	Potent UVB absorber; high SPF contribution

Antioxidant & Soothing Complex

Vitamin C	Antioxidant	—	Photo-oxidative defence; brightening synergy
Vitamin E	Lipid antioxidant	—	Cell membrane protection; regenerates Vitamin C
Allantoin	Soothing keratolytic	—	Reduces post-UV inflammation; sensitive skin safe

Mechanism of Action

A hybrid UV filter system — combining chemical and mineral filters for complete broad-spectrum coverage, boosted by antioxidants for photo-oxidative protection.

Tinosorb M + Tinosorb S — primary photostable broad-spectrum filters. Absorb UVB + UVA without generating free radicals. Prevent photodegradation of other actives in the formulation.

Zinc Oxide + Titanium Dioxide — mineral physical blockers. Sit on skin surface, reflect UV. Micronised to eliminate white cast on Fitzpatrick III–VI Indian skin.

Uvinal A Plus + Uvinal T 150 — targeted organic filters for UVA-I (deepest, photoaging) and UVB (high SPF contribution).

Vitamin C + Vitamin E — synergistic antioxidant pair. Vitamin E regenerates Vitamin C after oxidation, extending antioxidant activity beyond what SPF alone provides. Allantoin reduces post-UV inflammation, ensuring sensitive/post-procedure skin compatibility.

Dosage & Administration

Complete AM routine — cleanser, serum, moisturiser if prescribed.
Apply Photo Defense as the final step before stepping outdoors or exposure to screens.
Use ¼ teaspoon (approx. 1.5ml) for the face — do not under-apply, SPF scales with quantity.
Spread evenly over face, neck, and exposed areas — blend outward, do not rub vigorously.
Reapply every 2–3 hours when outdoors or under direct light.

Frequency

Every Morning · Non-Negotiable. Apply daily regardless of weather or indoor activity. UV penetrates glass — window exposure is sufficient for cumulative photodamage. Reapply 2–3 hourly outdoors.

Protocol Position

Mandatory in all 5 protocols (see "Mandatory in Every Protocol" section above). The only SkinQ Rx product prescribed across every range — photodamage is a compounding factor in every skin concern.

Post-Procedure Use

Mandatory after all laser, peel, and microneedling procedures. Compromised skin barrier has zero UV defence — omitting SPF post-procedure is clinically contraindicated. Particularly critical for Fitzpatrick IV–VI patients where unprotected post-procedure UV exposure causes direct PIH rebound.

Skin Type Suitability

Gel texture designed for Indian climate — non-greasy, non-comedogenic, safe for oily, acne-prone, and post-procedure skin. Validated zero white cast on Fitzpatrick III–VI Indian skin tones.

Storage

Store below 25°C. Keep away from direct sunlight — heat degrades organic UV filters. Use within 12 months of opening. Do not freeze.
