If I use retinol under eyes, will it help increase collagen to improve sunk eyes?
Prescription strength Retin-A/Tretinoin is a great maintenance product for fine lines and uneven skin tone when used long term, and can improve the overall quality of your skin. However, it will not likely generate enough collagen to fill a hollow area. For hollowing, dermal fillers like Restylane are a great option for camouflaging the sunken area and blending it with your cheek contour. For a longer lasting option, fat transfer is great alternative. Good luck.
Yes, retinol can help with fine lines and to stimulate collagen production in the skin around the eyes. This is one reason a small amount of retinol is included in a lot of the over the counter eye creams. However, it will not help much with tear trough deformity or sunken eyes. HA fillers like Restylane are commonly used to treat tear trough deformities.
