As you age, so does your skin. For some who follow a healthy lifestyle the picture is good, but for others who function on whim, the picture is worth an alteration. In your 30s, just like you, your skin is no longer bothered by the outside, now it's relying on what remains inside. This is when the skin gives you warning signs for attention and care in the form of pigmentation, acne, hair fall, fine lines and more. But what to pay attention to and what are these signs pointing towards? Here's your guide to understanding your skin as your internal health report card and taking points where you go wrong. Pigmentation One of the most common skin concerns in the 30s is pigmentation and hyperpigmentation. This is when you end up turning to social media influencers and spending an inexplicable amount on random serums promising to undo it all. While you might erase what's on the outside, what about the inside, where the larger problem lies? What does it indicate: Pigmentation in the 30s can be an accumulative result of the UV damage in your 20s. But it can also be a reaction to the hormonal changes you experience with pregnancy, birth control, PCOS, stress and more. If the pigmentation is consistent, it could indicate:Hormonal imbalance, 2020 Journal of Clinical and Aesthetic Dermatology studyThyroid dysfunction, 2015 Advances in Dermatology and Allergology studyHigh levels of cortisolVitamin B12 or folate deficiency, 2022 Cureus studyAcne Break-outs in your 30s can break your heart and day, but they are common.
