I ka hoʻoholo ʻana i ka huaora C i kūpono iā ʻoe, e noʻonoʻo i kou ʻano ʻili, wahi a Kauka Frank. "ʻO ka Vitamin C, ma keʻano o ka L-ascorbic acid, ka mea ikaika loa, akā hiki ke hoʻonāukiuki i kaʻili maloʻo a maʻalahi paha," wahi āna. "No ka ʻili oʻo aʻe, ʻo THD ascorbic acid ka momona a hiki ke loaʻa i loko o kahi ʻano lotion moisturizing."

Paipai ʻia no ka ʻili ʻaila SkinCeuticals CE Ferulic me 15% L-Ascorbic Acid, ka mea e hoʻohui i ka huaora C me ka 1% ka huaora E a me ka 0.5% ferulic acid. No ka ʻili maloʻo e hoʻāʻo L'Oréal Paris Revitalift Derm Intenves Vitamin C Serum, ka mea e hoʻohui i ka 10% vitamina C me ka hyaluronic acid e huki ai i ka makū.
