Thank-you so much for your question. Yes, it is advisable that you use a moisturiser in summer, BUT it’s really important that you use the correct moisturizer for YOUR skin. I cannot really offer you too much advice on the Neutrogena range as I’m not too familiar with it. My very best advice for you is to have a proper skin analysis that identifies what your skin needs and then choose your products appropriately. It is also exceptionally important that you use a good SFP on a daily basis.
