Let’s start off with the most common ingredient to avoid in acne products: Alcohol! 

When consumed, alcohol can really dry out the skin and increase the possibility of inflammation below your skin, causing way more break outs than usual. 

When used in products, alcohol can dry out the skin and strip it away from natural oils, causing the over production of sebum. Too much sebum can eventually clog pores, causing break outs to occur. 

While some fragrance compounds — look out for terms like parfum, linalool and essential oils — won’t cause sensitive skin to break out, it’s better to stay away from them entirely. 

First of all, silicone isn’t all bad. Various types of silicone include dimethicone and methicone and what they do is that, it gives your products that easy silky feel — making it easy for products to glide on and slip on. 

However, those with sensitive and acne prone skin can sometimes find that silicones can clog their pores and cause break outs.
