Each serum targets hydration differently: Our Hyaluronic Acid Serum provides universal moisture for all skin types with lightweight comfort. Ectoin Serum hydrates whilst strengthening compromised or sensitive skin barriers with stress-protection technology. Exosome Hydro-Glow Complex delivers deep hydration plus visible brightening benefits for dull, tired-looking skin.
These aren't ordinary hydrating serums – each uses cutting-edge technology. Ectoin is a natural extremophile molecule that protects and repairs, Exosomes are advanced cellular communication particles that improve skin function, and our multi-weight Hyaluronic Acid penetrates multiple skin layers. Most serums use basic humectants; ours deliver hydration through innovative pathways
Yes! Layer from thinnest to thickest consistency. Many customers love combining serums for comprehensive hydration – try Hyaluronic Acid as your base layer, then add Ectoin for barrier support or Exosome for brightening benefits. Always finish with your regular moisturiser to lock everything in.
Think of these as your hydration foundation. If you're using targeted treatments from other ranges (like Retinol for anti-ageing or Salicylic Acid for breakouts), apply your hydrating serum first. Properly moisturised skin responds better to active ingredients and experiences less irritation from treatments.
Absolutely! Oily skin often overproduces sebum to compensate for underlying dehydration. Our lightweight serum formulas absorb quickly without adding greasiness or clogging pores. The Exosome complex is particularly beneficial for oily skin as it improves overall skin function whilst delivering essential hydration.
You'll notice immediate plumping and comfort after first application. For longer-term benefits like improved skin texture, strengthened barrier function, and that healthy glow, give it 2-4 weeks of consistent twice-daily use. Hydrated skin is healthy skin – and healthy skin always looks and feels its best.
