Dermatologists aren’t sure why azelaic acid is so effective at clearing up inflammation, but it’s often used as an option for sensitive skin or pregnant patients. Linkner says the ingredient is good at treating malasma, acne, and rosacea. Your dermatologist can prescribe a foam product with azelaic acid, and you can also find beauty products with very small amounts of this active ingredient.
Genetics is thought to be the primary cause of acne in 80% of cases. The role of diet and cigarette smoking is unclear, and neither cleanliness nor exposure to sunlight appear to play a part. In both sexes, hormones called androgens appear to be part of the underlying mechanism, by causing increased production of sebum. Another frequent factor is excessive growth of the bacterium Cutibacterium acnes, which is normally present on the skin.
Castor oil has anti-inflammatory and antibacterial properties that can speed up healing, making it ideal for breakout-prone skin. Though I recommend using it in very small amounts with jojoba oil, hemp seed oil or coconut oil, along with one of the essential oils above, it’s high in unsaturated fatty acids, vitamin E, proteins and minerals, which can help reduce acne-causing bacteria and inflammation associated with breakouts. It can even help heal scars caused by acne.
Acne treatment that you apply to the skin: Most acne treatments are applied to the skin. Your dermatologist may call this topical treatment. There are many topical acne treatments. Some topicals help kill the bacteria. Others work on reducing the oil. The topical medicine may contain a retinoid, prescription-strength benzoyl peroxide, antibiotic, or even salicylic acid. Your dermatologist will determine what you need.
