try using a natural oil like grapeseed, jojoba, or sweet almond oil. I've never had issues with skin sensitivity on my clients when using these oils. I wouldn't use a scented one at first just to be on the safe side.

Sweet almond is the best for sensitive skin. As long as you know that he isnt allergic to the essential oil that you add to it, you can add a few drop of whatever fragrance you want to it. I would recommend that you do a small patch test before you try and do a full massage. Be careful when you use essential oils though as they can cause anything from redness, swelling, or rash to burning and possibly even full airways closing up if the person is allergic.
