Formulated by Dr Yilmaz, the Winter Hyaluronic Acid Serum is the ultimate serum for dry, dehydrated skins. Containing a blend of lactic acid, hyaluronic acid and ceramides to support your skins natural moisuturising factor (NMF), the Winter Hyaluronic Acid serum can be used all year round and will leave your skin feeling well hydrated. Designed to improve your skins hydration levels, this serum will also help reduce the appearance of fine lines and improve your skins overall tone and complexion. We recommend introducing on alternate mornings and building to daily tolerance. The use of an SPF50+ is recommended as AHA’s have the potential to increase sun sensitvity.
