Skin Tech Melablock-HSP SPF50

Skin Tech Melablock-HSP SPF50 is a very high protection 4-in-1 daily sunscreen formulated using innovative Heat Shock Protein (HSP) technology, offering over 98% broad-spectrum UVA and UVB protection. Combining physical and chemical UV filters, erythema protection, antioxidant defence and endogenous HSP activation, it delivers a level of protection that goes significantly beyond standard sunscreens. Suitable for all skin types including sensitive skin, it is essential daily protection for anyone undergoing or recovering from a Skin Tech chemical peel protocol, and is equally effective as a standalone daily sunscreen for year-round use.

What sets Melablock-HSP SPF50 apart is its ability to actively stimulate the skin's own production of Heat Shock Proteins — naturally occurring cellular defence proteins that decline with age and protect against the protein denaturation and thermal cell lysis triggered by UV radiation, heat and environmental stress. Micronised Titanium Dioxide physically reflects UV rays before they penetrate, while stable chemical sun filters absorb any residual radiation. Tocopheryl Acetate (Vitamin E) and Bisabolol further protect against free radical damage and photoageing, while also helping to slow melanocyte activation and reduce the risk of post-inflammatory hyperpigmentation. Apply every morning as the last step of your skincare routine and reapply every two hours when in direct sunlight.

Benefits

• Very high SPF50 protection — blocks over 98% of UVA and UVB radiation with a dual physical and chemical filter system
• Activates the skin's natural Heat Shock Protein production to defend against cellular damage from UV-induced thermal stress
• Slows melanocyte activation to reduce the risk of hyperpigmentation, dark spots and post-procedure discolouration
• Protects against blue light, pollution and free radical damage with a boosted antioxidant complex — essential daily protection post-peel, post-laser and post-IPL

Key Ingredients

• Micronised Titanium Dioxide (Physical Sun Filter) — a mineral UV blocker that physically reflects UVA and UVB rays away from the skin's surface before they can penetrate and cause cellular damage
• Stable Chemical Sun Filters (UVA/UVB) — a next-generation blend of chemical filters that absorb residual UV energy passing through the physical block, providing comprehensive coverage across the full UV spectrum
• Heat Shock Protein (HSP) Inducer — stimulates the skin's endogenous production of HSPs, which protect skin proteins against denaturation and thermal cell lysis caused by UV exposure, heat and environmental aggressors — production of which naturally declines with age
• Tocopheryl Acetate (Vitamin E) — a potent, stable antioxidant that neutralises free radicals generated by UV exposure, helps prevent photoageing and supports post-sunburn skin recovery
• Bisabolol — a plant-derived soothing and regenerating agent that reduces erythema, calms sensitised skin and enhances the overall tolerability of the formula on post-procedure complexions
