Niacinamide (tone-evening) and allantoin (soothing) are also included to care for skin post-peel. Recommended for those concerned with excess sebum, makeup lifting due to dead skin buildup, and shine. Due to the high acid concentration, use 1–2 times per week.\u003c\/p\u003e","brand":"ISNTREE","offers":[{"title":"Isntree Hyper Acid4 AHA BHA PHA LHA 30 Serum 20ml","offer_id":41365131395136,"sku":"4400-1","price":19.02,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0600\/8825\/4528\/files\/17924_202407151811450928_33661.jpg?v=1788852006","url":"https:\/\/piyonna.com\/products\/isntree-hyper-acid4-aha-bha-pha-lha-30-serum-20ml","provider":"PIYONNA","version":"1.0","type":"link"}
