With age, our skin experiences a decrease in the production of collagen, natural oils and elastin, in turn, making it dry and look lifeless. The skincare mistakes one may have made at a younger age start becoming visible in the late 30s or early 40s. This is also when wrinkles, fine lines, age spots start appearing on the skin. After 40, an ideal skincare regimen should include both corrective and preventive measures. This means that it should address the current concerns as well as prevent the skin from any further damage, explained Dr Nivedita Dadu, dermatologist, founder and chairman of Dr Nivedita Dadu’s Dermatology Clinic. *Include exfoliation in your beauty regimen. Choose a scrub according to your skin type, but it should not be harsh. For dry skin, use a cream-based scrub that will not only cleanse but also moisturise the skin. For oily skin, use a gel-based scrub that will help control oil secretion and give squeaky clean skin.*With age, the skin tends to lose moisture and many healthy fats. So, it becomes drier, more irritated, less supple and less elastic. Always use a gentle non-foaming cleanser and use a good moisturiser afterwards to lock in the moisture. Acne scars, pigmentation, blemishes and dark spots are the other byproducts of ageing. So, use a dark spot corrector which contains vitamin C and apply on the spots regularly to make them fade away. For medicated creams that can help reduce pigmentation, one should consult a dermatologist and avoid self-treatment.
