What sets gh apart from other pharmacy brands is the concentration and form of its actives. Using pure direct papain is not the same as using a papaya extract. Azeloglycine® — active at any pH without alcohol — is not the same as conventional azelaic acid. Anhydrous retinol stabilised in oil is not the same as water-based retinol. At gh, the difference between an active and its best-in-class form is the difference between marketing and efficacy.
Key actives across the catalogue include: triple hyaluronic acid (high molecular weight, acetylated and hydrolysed) for hydration at every skin layer; liposomal NP and NG ceramides for skin barrier repair; a full retinoid spectrum from introductory retinaldehyde to 0.3% pure retinol; pre/postbiotic complexes for dermobiome care; and next-generation depigmenting actives including tranexamic acid, 10% niacinamide and biotechnological Vitamin D3-like.
The Función Barrera Cremagel has received iDermo Silver and Bronze awards for Best Facial Product and is the brand's best-selling product. Several products have been developed in collaboration with key figures in Spanish dermatological communication: the Triple H Hydrating Essence and Kirē Cleansing Emulsion with Cristina Mitre, the exfoliating lotion 5 Azelaic-S also with Cristina Mitre, and the repairing cream Mano de Santo with Boticaria García. These are formulation collaborations, not endorsements: each creator was actively involved in the development of her product.
