Not all retinoids are made equally, adding a high dose of active to the bottle is easy...stabilising it, maximising potency and penetration whilst minimising irritation is not. Most brands aren’t able to. But we aren't most brands! When looking for a retinal, it’s important to consider the 4 ‘P’s to ensure your retinal delivers profound results and value for money, alongside a great experience without any irritation. Dr Pyal @drpyal gives her top tips when researching retinal products; 💎 Potency 💎 Patented Stability 💎 Professional-Grade Results 💎 Progressive Strengths #CrystalRetinal #Retinol #Retinal #Retinoids #Medik8 #Skincare #AntiAgeing #AntiAging
