FAQs

Our askINKEY digital skincare advisors are experts with deep product knowledge, here to answer your most asked questions and make skincare as simple as possible.

These products have earned their bestseller status through consistent results and rave reviews from our community. Each has 4+ star ratings, with many customers repurchasing multiple times. They're formulated with clinically-proven ingredients at concentrations that actually work, without the premium price tag you'd expect from comparable products.
It depends on your skin concerns! Our Hyaluronic Acid Serum (£9) is perfect for dehydration, the Salicylic Acid Cleanser (£12) tackles breakouts, and our Bio-Active Ceramide Moisturiser (£19) is ideal for anti-ageing. Not sure? Take our skincare quiz - it takes just 2 minutes and creates a personalised routine.
Most customers notice improvements within 2-4 weeks of consistent use. For hydration (Hyaluronic Acid), you'll see instant plumping effects. For breakouts (Salicylic Acid products), expect 4-6 weeks. Anti-ageing results (retinol, peptides) typically show in 6-12 weeks. Remember, consistency is key - our bestsellers work because people stick with them!
Absolutely! Many are designed to work together in a routine. However, be cautious with active ingredients like retinol and acids - these shouldn't be used simultaneously. Our product pages show you exactly what to layer and when.
Many of our bestsellers are formulated for sensitive skin, like the Oat Cleansing Balm and Bio-Active Ceramide Moisturiser. We clearly label any products with active ingredients that might cause irritation. When in doubt, patch test first or start with our gentler formulas. Our askINKEY team can help recommend the best options for your skin type.
We believe knowledge should be accessible, not gatekept. Every product clearly states what it does, how to use it, and what to expect - no marketing fluff. Our prices reflect the cost of quality ingredients and research, not fancy packaging or celebrity endorsements. Most importantly, our community of millions shares honest reviews, so you know these bestsellers actually deliver results.
