Hyperpigmentation is a common skin condition that can be caused by sun damage, acne scars, hormonal changes, and certain medications. There are several ways to reduce hyperpigmentation, including over-the-counter (OTC) treatments, professional procedures, and natural ingredients. Here are some product details, positive and negative aspects, and ingredients or materials to look for:
- OTC treatments:
- Look for products containing ingredients like vitamin C, licorice root, kojic acid, azelaic and glycolic acids, and retinoids.
- Effective OTC moisturizers should contain moisturizing agents like glycerin or hyaluronic acid, and maybe even a retinol to boost cell turnover.
- Some OTC products may take longer than professional treatments to show results.
- Professional procedures:
- Chemical peels, microdermabrasion, dermabrasion, and laser therapy are some of the options available.
- These procedures can produce more dramatic results than OTC treatments.
- Care must be taken not to worsen matters by causing inflammation.
- Natural ingredients:
- Some natural ingredients that have shown efficacy as depigmenting agents include azelaic acid, soy, lignin peroxidase, ascorbic acid iontophoresis, arbutin, ellagic acid, licorice extracts, niacinamide, and mulberry.
- Green tea and turmeric are clinically efficacious in treating melasma and facial hyperpigmentation, respectively.
- Despite the limited evidence-based research, several natural ingredients did show efficacy as depigmenting agents.
It is important to note that people should choose products that are suitable for their skin type and tone. Also, some products may cause skin irritation or allergic reactions, so it is recommended to do a patch test before using them. Finally, it is always a good idea to consult a dermatologist before starting any treatment for hyperpigmentation.
