These Common Skincare Ingredients Could Be Doing More Harm Than Good

Vitamin C is more than just a common cold antidote — it’s also a highly sought-after skincare ingredient because of its anti-inflammatory, brightening, and skin-renewing qualities. However, it isn’t for everyone. Vitamin C is highly acidic, which means prolonged exposure can cause itchiness, redness, and general irritation for those with sensitive skin, per Medical News Today

Skin that’s left raw and inflamed from vitamin C is more prone to breakouts, particularly for those with sensitive skin. If you’re noticing adverse side effects after using a product that contains vitamin C, it’s best to stop using the product and let your skin recuperate before finding a vitamin C serum appropriate for sensitive skin. 

Unfortunately, biotin is another well-loved ingredient that can be just as detrimental. Taking biotin every day can help promote strong, healthy skin and nails, and it can also help your body process carbs, proteins, and fats into energy. But according to a study published in The Journal of Nutrition, excess biotin might impact the body’s ability to regulate its oil glands, and too much sebum can lead to excess oiliness and breakouts. While the Dermatology Clinic states that this research is limited and not hard and fast proof of biotin’s connection to acne, it’s worth limiting your biotin use if you notice excess breakouts.
