A two-piece SKIN1004 set covering the two steps most routines get wrong: repairing the barrier at night and protecting it properly by day. It pairs the Madagascar Centella Probio-Cica Intensive Ampoule with the Hyalu-Cica Water-Fit Sun Serum, both in 50 ml full sizes and both built on centella asiatica grown in Madagascar.

The ampoule works on barrier lipids and inflammation. Centella supplies the triterpene fraction — asiaticoside, madecassoside, madecassic and asiatic acid — which moderates the inflammatory signalling behind redness and reactivity. Ceramide NP replaces a lipid the skin makes less of when stressed, Lactobacillus ferment supports the skin's microbial environment, and Niacinamide drives barrier lipid production. The sun serum then takes over by day: SPF 50+ PA++++ from four photostable organic filters — Diethylamino Hydroxybenzoyl Hexyl Benzoate, Ethylhexyl Triazone, Methylene Bis-Benzotriazolyl Tetramethylbutylphenol and Diethylhexyl Butamido Triazone — chosen because they hold up under UV rather than degrading within the hour. It carries Centella Asiatica Extract at 9,800 ppm alongside niacinamide and hyaluronic acid, so the protection step also calms.

Both are fragrance-free and free of essential oils. The ampoule is silky and absorbs without residue; the sun serum is fluid, with no white cast.

Key ingredients

• Centella Asiatica Extract — the anchor of both products; its triterpenes calm redness and support repair. Present at 9,800 ppm in the sun serum.
• Ceramide NP — restores a key barrier lipid in the ampoule, cutting water loss through a compromised surface.
• Lactobacillus ferment — the 'probio' element; supports a balanced skin surface environment.
• Niacinamide — in both steps; strengthens barrier function, evens tone, moderates sebum.
• Four photostable UV filters — deliver SPF 50+ PA++++ broad-spectrum cover without a white cast.

How to use

1. Cleanse and tone.
2. Apply the Probio-Cica Intensive Ampoule to the whole face and press in.
3. Follow with moisturiser if your skin needs it.
4. In the morning, finish with the sun serum as the last skincare step, using roughly two finger-lengths for face and neck.
5. Reapply the sun serum every two to three hours during prolonged sun exposure.

Recommended frequency

• Sensitive or reactive skin — ampoule twice daily, sun serum every morning.
• Dry skin — ampoule twice daily under a richer cream.
• Oily or combination skin — ampoule at night, sun serum daily.
• Timeline — reduced tightness within days; visible reduction in redness usually after three to six weeks. Sun protection is immediate.

Best suited to

Sensitive, redness-prone or barrier-compromised skin, and anyone rebuilding a routine after over-exfoliation. Those who prefer mineral sunscreen should note the filters here are organic.

Good to know

Both products are fragrance-free and essential-oil free, which is why the set suits reactive skin. The ampoule contains cetearyl alcohol and stearic acid, so it is not malassezia-friendly if you are managing fungal acne. Organic UV filters can sting if they migrate into the eyes, so keep the sun serum slightly away from the lash line. SPF performance depends entirely on applying enough and reapplying. Store away from heat and direct sunlight.
