What Your Cleanser Is Actually For
Cleansers do one job: remove dirt, oil, and impurities—without upsetting your skin’s natural balance. The right formula does this by using gentle surfactants, hydrating ingredients, and pH-balancing agents to keep your skin happy and healthy.
The Key Ingredients in Your Cleanser
Here’s a quick breakdown of what makes a cleanser work:
Surfactants (The Cleansers)
Surfactants lift away dirt, oil, and makeup. One type, micelles, attract impurities and rinse away with water, leaving your skin fresh without feeling dry.
💡 Fun fact: Micellar water gets its name from micelles! They’re little cleansing bubbles that trap and remove impurities.
Hydrating Agents (The Moisture Lockers)
Glycerin and hyaluronic acid keep your skin soft after cleansing. These ingredients help lock in moisture, preventing dryness and leaving your skin feeling nourished.
pH Balancers (The Skin Protectors)
Your skin’s barrier works best at a pH of around 5.5. A well-balanced cleanser helps maintain this pH, preventing irritation and dryness.
How to Choose the Right Cleanser for Your Skin
When choosing a cleanser, keep it simple. Look for formulas that cleanse without stripping your skin’s natural oils. Here’s what to prioritise:
Key Ingredients to Look For
- Gentle Surfactants: Ingredients like Coco-Glucoside and Sodium Cocoyl Isethionate clean your skin gently without removing essential oils.
- Hydrating Agents: Glycerin and Ceramides lock in moisture, keeping your skin soft and hydrated.
- pH-Balanced Formulas: Choose a cleanser with a pH around 5.5 to keep your skin in balance.
- Soothing Ingredients: Aloe Vera and Panthenol can calm sensitive skin, although not every cleanser needs them.
Ingredients to Avoid
Some ingredients can be too harsh for your skin, especially if you have sensitive skin. Avoid these:
- Harsh Surfactants: Sodium Lauryl Sulfate (SLS) can strip your skin’s natural oils.
- Drying Agents: Alcohol and benzyl alcohol can cause irritation and dryness.
- Fragrances: These can trigger reactions, especially for sensitive skin.
💡 Fun fact: Sodium Lauryl Sulfate (SLS) is often found in soaps and cleansers because it’s effective at removing dirt. However, its strong cleansing properties may leave your skin feeling dry or irritated.
