Will dermal fillers improve the darkness/pigmentation under eyes? (Photo)

The short answer to your question is Yes, I.e. dermal fillers can often help diminish under eye darkness, especially, as in this case, when there are significantly deep tear trough, since the filler can not only elevate and smooth transition between the upper cheek and the under-eye, but create some distance from the underlying blood vessels that are contributing to the darkened appearance.
If still necessary for further lightening, a series of in-office superficial peels supplemented by the regular, at-home use of Rx topical lightening agents can further improve skin color.
You would be wise to consult with a board certified cosmetic dermatologist who can help you with all these issues. Best of luck.

When addressing concerns about darkness or pigmentation under the eyes, it's important to understand the potential causes and appropriate treatments. Dermal fillers can be effective in certain cases, but they are not a universal solution for all types of under-eye darkness.

Darkness under the eyes can be caused by a variety of factors, including:

Volume Loss: As we age, we lose fat and collagen in the under-eye area, which can create a hollow appearance and shadowing that contributes to the appearance of dark circles. In these cases, dermal fillers can help by restoring volume and reducing the shadowing effect.

Hyperpigmentation: If the darkness is due to increased pigmentation, fillers may not be effective. In such cases, treatments like topical lightening agents, chemical peels, or laser therapy might be more appropriate.

Vascular Issues: Sometimes, dark circles are due to visible blood vessels or thin skin in the area. Fillers can sometimes help by thickening the skin, but other treatments may be needed to address vascular issues specifically.

Lifestyle Factors: Lack of sleep, dehydration, and allergies can also cause or exacerbate dark circles. Addressing these factors can improve the appearance of the under-eye area.

For a personalized assessment, it's best to consult with a dermatologist or a qualified aesthetic practitioner. They can evaluate the specific causes of under-eye darkness and recommend the most suitable treatment options.

From the submitted photos it appears that the darkness that concerns you is created in part by shadowing from the lower lid contour. Filler may improve this somewhat. It appears you would be a candidate for a lower blepharoplasty with fat grafting. This would improve the appearance of the under eye including the shadowing.
