Retinol is a popular skincare ingredient known for its anti-aging benefits, but it can sometimes cause skin darkening, a phenomenon known as post-inflammatory hyperpigmentation (PIH).
What is Post-Inflammatory Hyperpigmentation?
PIH occurs when your skin produces excess melanin, the pigment responsible for skin color, in response to inflammation or injury. Retinol can cause skin irritation, redness, and dryness, which can trigger PIH.
Reasons Why Your Skin Might Be Getting Darker After Using Retinol:
- Sensitivity: Some people are more sensitive to retinol than others. If you have sensitive skin, you may be more prone to PIH.
- Incorrect Application: Applying too much retinol or using it too frequently can irritate your skin and increase the risk of PIH.
- Sun Exposure: Sunlight can worsen PIH, so it's crucial to wear sunscreen daily, even when using retinol.
- Other Skincare Products: Using retinol with other irritating ingredients, like exfoliating acids, can increase your risk of PIH.
How to Prevent or Minimize Darkening:
- Start Slowly: Begin by using retinol once or twice a week and gradually increase the frequency as your skin tolerates it.
- Use a Gentle Cleanser and Moisturizer: Avoid harsh products that can further irritate your skin.
- Apply Sunscreen: Wear a broad-spectrum sunscreen with SPF 30 or higher every day, even on cloudy days.
- Exfoliate Gently: Using a gentle exfoliator can help remove dead skin cells and improve product absorption.
- Consult a Dermatologist: If you experience persistent darkening, consult a dermatologist for personalized advice.
Remember: If you experience severe irritation or darkening, discontinue use and consult a dermatologist.
