Power-Packed Benefits for All South African Skin Types
- Deep, Gentle Exfoliation: Features a powerhouse blend of 30% four acid complex (AHA, BHA, PHA & LHA) for dramatically smoother and refined texture, yet gentle enough for regular use.
- Controls Excess Oil: No more shine or midday greasiness. Specially balanced to keep South African skin matte and fresh, even in humid or dry conditions.
- Brightens and Evens Tone: Concentrated Niacinamide fights hyperpigmentation and sun-induced dark spots, leaving your skin luminous and healthy-looking.
- Pore & Blemish Rescue: Natural Charcoal Powder unclogs pores, reducing blackheads and breakouts for ultra-clear skin.
- Youthful Bounce: Peat water helps boost elasticity and visibly plumps skin for that youthful “snap-back” feel.
- Hydration Assurance: Allantoin and balancing actives ensure you get exfoliation with serious moisture, not dryness.

- Tone: Use a hydrating toner to prep your skin for even absorption.
-
Apply Serum:
- Dispense a pea-sized amount onto dry fingers.
- Smooth over entire face, focusing on congested areas (t-zone, cheeks, chin).
- Moisturise: Seal in with a nourishing moisturiser (shop our Isntree Hyaluronic Acid Aqua Gel Cream for optimal results).

Safety Tips
- Patch test before first use.
- Do not mix with other direct acids or retinol in the same routine.
