よくある質問

スキンケア成分への反応はなぜ起きますか?

成分への皮膚反応は主に3種類に分類されます:刺激性接触皮膚炎(免疫非介在型の直接刺激反応)、アレルギー性接触皮膚炎(特定の増感剤に対する免疫介在型反応)、偽アレルギー反応。香料と防腐剤は化粧品によるアレルギー性接触皮膚炎の最も一般的な原因です。刺激反応は高濃度酸・高アルコール製品・物理的スクラブによるものが多いです。

フレグランスフリーの製品は敏感肌に向いていますか?

香料感受性またはアレルギー性接触皮膚炎が疑われる方には、フレグランスフリー製品が一般的な増感剤への暴露を減らします。EUではリーブオン製品で0.01%超の26種香料アレルゲンを成分表示する義務があります。「フレグランスフリー」と「無香料」は異なります:無香料製品にはマスキング用香料が含まれている場合があります。敏感肌には「フレグランスフリー」がより安全な選択です。

ナイアシンアミドは敏感肌に向いていますか?

臨床データでは、ナイアシンアミドは最大5%濃度でほとんどの肌タイプ(敏感肌含む)に対して良好な忍容性を示しています。研究によると、セラミドや脂肪酸の合成を促進し肌バリアを強化することで、時間の経過とともに敏感性を軽減する可能性があります。一部ユーザーが感じる「フラッシング感」はナイアシンアミド自体ではなく、通常はニコチン酸(Niacin)の不純物が原因とされています。
