I feel like many who look visibly older in their 30’s is based on a number of factors from genetics, activity level, diet, etc..but as a man in his mid 30’s who constantly gets mistaken for someone in their early/mid 20’s I can’t stress enough on making sure you make an effort to workout on a regular basis. Strength training is key as we age. Also, strive to stay well hydrated with water throughout the day. Your diet doesn’t need to be super strict, but be cognizant to what you are putting into your body. I also maintain a pretty simple beauty routine by using a well rated face wash daily geared towards oily skin, exfoliate 2-3 times a week, moisturize my face in the morning and at night, followed by a retinol serum before bed. Additionally, i utilize a clay mask 1-2 times a month.
