Yes, I think it is very important. Many patients come to my OPD with similar questions, saying that they applied certain creams or serums and noticed redness or irritation afterward.
Some components in these products, like retinol, are notorious for causing sudden redness, especially if you have a history of eczema or atopic dermatitis. Consulting a dermatologist is essential because the small details of your skin, which you may not notice yourself, can be identified by an expert.
For example, the moisturizer for your face is never the same as the moisturizer for your body. Hands, feet, and body all require different formulations.
A dermatologist can guide you on which product to apply, where, and in what quantity, helping you avoid dullness, irritation, or worsening of your skin condition. So, it is always better to consult an expert before starting any new cream or serum.
