My mistake, I slipped in some em dashes. Here is the clean version:

Arencia Retinal Booster Shot

A concentrated Vitamin A treatment built around one of skincare science's most powerful and increasingly sought-after actives. The Arencia Retinal Booster Shot formulates with Retinaldehyde, known as Retinal, a form of Vitamin A that sits one conversion step closer to the skin's active retinoic acid than conventional retinol, making it significantly more efficient and noticeably faster-acting in its results.

Where retinol requires two conversion steps before the skin can utilise it, Retinal requires only one. This means a greater proportion of what is applied actually reaches its target, translating to more visible improvements in cell turnover, collagen stimulation, fine line reduction, and skin texture refinement, often in a shorter timeframe and at lower concentrations than retinol would require to achieve the same outcome.

The Booster Shot format positions this as exactly what the name describes: an intensive, targeted dose of a high-performance active delivered with precision. At 30ml of concentrated formula, this is a treatment for those who are serious about their skin and ready to incorporate one of the most clinically validated ingredients in anti-ageing skincare into their routine.

Suitable for: All skin types. Beginners to Vitamin A actives should start slowly and build frequency over time. How to use: Apply a small amount onto cleansed skin in the evening, avoiding the immediate eye area. Allow to absorb fully before following with moisturiser. Begin with 2 to 3 times per week and increase frequency as skin tolerance builds. Always apply SPF the following morning.
