Everyone knows that using sunscreen is one of the most important steps for protecting the skin from harmful sun rays, but dermatologists explain that it isn't the only thing you should do to keep your skin healthy. Other daily routines are also important for minimizing sun damage and maintaining healthy skin over time.Protecting The Skin BarrierSkin is a protective barrier for the body but constant exposure to the sun, pollution, heat and unhealthy lifestyle habits can make this barrier vulnerable. Once the skin barrier is damaged, the skin is more susceptible to tanning, pigmentation, dryness, sun ageing and other sun damage.Moisturising Supports Skin HealthUsing a moisturiser every day is a very simple, yet effective habit. A good moisturiser is one that doesn't contain any scents and will support the barrier function of the skin, thereby preventing unwanted water loss from the skin. Wet and plump skin is resistant to the environment and sun's rays.Also read: Add These 8 Foods To Your Diet For Batter Hair, Skin And NailsAntioxidants Help Fight Sun DamageAntioxidants are also a best practice for dermatologists. Antioxidants prevent the damage to skin cells by free radicals created by UV exposure, pollution etc. This protection can help minimize issues like hyperpigmentation, uneven skin tone and premature ageing. Consuming foods that contain antioxidants (such as fruits, vegetables and nuts) can help keep skin healthy on the inside.Stay Hydrated For Healthier SkinNext, hydration is crucial. It's important to keep drinking enough water all day long to keep the skin supple and to allow the skin to repair itself. Moisture also contributes to skin's healing from environmental stress.Physical Sun Protection MattersSun protection is also of great importance. Wearing hats or caps, using umbrellas, and wearing clothing that protects against the sun's rays can minimize direct exposure to the sun. All these are simple actions that serve as a physical barrier and prevent sunburn and long term damage to the skin, particularly between 10 a.m. and 4 p.m. These simple steps provide a physical barrier and reduce the risk of sunburn and chronic skin damage, particularly in the peak hours of 10 a.m. to 4 p.m.Also read: Dermatologist Reveals What To Add And Remove From Skincare Routine For Season ChangeGut Health And Skin ConnectionAnother focus has been on the connection between gut health and healthy skin, as experts recognize how crucial the role of the gut is in maintaining healthy skin. Probiotics can potentially improve the gut-skin axis and aid in the healing process and alleviate inflammation in the body. The better the gut environment, the better the skin will be able to recover and the less the exposure to the sun will age the skin.Collagen May Support Skin Repair Some people can use collagen supplements as an added benefit. Collagen is involved in supporting the dermis, the skin's structural component. Keeping collagen high can help promote skin repair and healing mechanisms.Doctors say while sunscreen is important, long-term skin protection can be achieved through a variety of healthy habits, proper nutrition, hydration and physical sun protection measures, which must be followed daily.Dr. Pravin Banodkar Senior Consultant Dermatologist Saifee Hospital
