About

What is Under My Skin is a plain-language guide to the ingredients in cosmetics: what they are, what they do, and what the evidence actually says about them.

Why it exists

Most ingredient lists are unreadable. Most skincare advice online is either marketing or fear. Here, every ingredient gets the same treatment: its function in the formula, how much is normally used, and honest notes on irritation, acne risk and safety.

What this site is not

It is not medical advice and it is not a shop. If you have a skin condition, your dermatologist decides your treatment — not a website.

How it is made

The site is written and edited with the help of an AI assistant, and checked against published sources. We are not perfect. When we get something wrong we correct it openly — tell us and we will fix it.

بالعربي

ما تحت جلدك دليل مبسّط لمكوّنات مستحضرات التجميل: شو هي، شو تسوّي، وشو تقول الأبحاث عنها.

هذا الموقع مو نصيحة طبية، ومو متجر. إذا عندك حالة جلدية، الطبيب هو اللي يقرّر علاجك.

نكتب المحتوى بمساعدة مساعد ذكاء اصطناعي، ونراجعه على مصادر منشورة. لو غلطنا، نصحّح علناً — راسلنا.
