Start with an AM and PM routine. For the AM routine, use a gentle cleanser followed by a moisturiser and a sunscreen. For the PM routine, use a cleanser followed by a serum, sealed in with a moisturiser. (In pic: Dollie Solanki and Dr Manisha Kothari)

If you use make-up daily or are exposed to air pollution, include double cleansing in your routine. Double cleansing starts with an oil-based cleanser, which helps to remove the dirt and make-up followed by a water-based cleanser.

Adequate hydration is essential for skin homeostasis to maintain your skin barrier and for tissue elasticity. Hydration is just not external in the form of moisturisers but also internal. Drink two to three litres of water, and explore supplements containing N-acetyl cysteine, vitamin B3, B6, B9, B12 and D3 and Himalayan pink salt. (Kareena Kapoor Khan and (right) Solanki)

For dry skin, choose a moisturiser containing shea butter, ceramide or glycerine in a cream based or ointment-based formulation. For oily skin, a hyaluronic acid-based oil-free light-weight gel-based moisturiser would be ideal. For combination skin, pick a lightweight gel moisturiser containing hyaluronic acid, glycerine and dimethicone. (In pic: Nayanthara)

Use a retinol-based serum for ageing concerns. If you are starting out with retinol, try the sandwich technique that involves washing your face with gentle cleanser, applying a moisturiser, topping it with a retinol serum, and then finally sealing the serum in with another layer of moisturiser. This helps your skin to adapt to the molecule, thereby avoiding the irritation and breakouts from retinol. (In pic: Diana Penty)
