Requesting a credit limit increase on a credit card can affect your score in which two ways?

When you request a credit limit increase, many issuers perform a hard inquiry on your credit report, which can temporarily lower your score by a few points. However, if your balances remain unchanged and your total available credit increases, your credit utilization ratio — which accounts for about 30% of your FICO score — improves, which benefits your score over time. Some issuers offer soft-inquiry limit increases, which carry no score penalty at all.
