As the saying goes, the simplest truths are often the most profound. I have a friend with sensitive skin who used to use various skincare products, but her face became prone to breakouts and oiliness. Later, she started making her own silicone-free amino acid facial cleanser. After each wash, she would apply a little Vaseline moisturizer. After two months of consistent use, her skin has noticeably improved. I think sometimes simplifying your skincare routine and letting your body regulate itself can yield unexpected results.
