Does Retin A firm the skin on face and neck?

Retin-A does firm up skin by
stimulating collagen remodeling and thickening the epidermis which
strengthens skin and improves wrinkles wherever you use it – face, neck,
chest, hands….. It also treats acne and improves actinic keratosis
or precancerous lesions caused by sun exposure.

Sort of...not really.... Retin A causes your skin cells to turn over faster which results in better skin tone and texture. It doesn't "firm" but since cells turn over faster the skin looks better and tighter and pores appear smaller, which overall makes the skin look better and younger."This answer has been solicited without seeing this patient and
