Sodium Lauryl Sulfate
Sulfate
Sulfates are used in skincare for their strong cleansing and foaming abilities, helping to remove dirt, oil, and buildup from the skin.
Can worsen Dry Skin
Some ingredients have the potential to dry out skin, especially in higher concentrations or for those with already dry or sensitive skin. Not everyone will experience dryness from them. How your skin reacts can depend on the product, concentration, and your unique skin type.
Can worsen Oily Skin
These ingredients are known to potentially contribute to excess oil or shine, but they don’t affect everyone the same way. Skin can be oily for many reasons, so it’s always a good idea to consider your unique skin needs when choosing products.
May cause Irritation
These ingredients are considered potential irritants, meaning they can cause irritation - but not necessarily for everyone. Everyone’s skin is different, so what bothers one person’s skin may be completely fine for someone else.
