7. AHAs – The Gentle Exfoliators

How to Read a Skincare Label

• Ingredients are listed in order of concentration: The first five ingredients usually make up the bulk of the product.

• “Fragrance” can be irritating: If you have sensitive skin, avoid products with synthetic fragrances.

• Patch test new products: Especially when using active ingredients like retinol or acids.

Tips for Beginners

1. Start slow – Introduce one new ingredient at a time to avoid irritation.

2. Know your skin type – Understanding whether your skin is oily, dry, sensitive, or combination will help guide your choices.

3. Don’t fall for marketing alone – A product is only as good as its ingredients. Learn to read labels, not just buzzwords.
