Ressecado vs. ressequido
These two adjectives both translate to parched or extremely dry, but they carry different nuances regarding the intensity and permanence of the condition. Generally, ressecado implies a temporary lack of moisture, while ressequido suggests a more permanent, withered, or shriveled state.
Ressecado
B2This word describes something that has lost its natural moisture or hydration. It is commonly used for biological tissues (like lips, skin, and hair) or surfaces (like soil) to indicate a dryness that is often superficial or reversible.

(My lips get parched when the weather is very cold.)

(Don't eat that bread, it is old and dry.)
Ressequido
C1This word conveys distinct intensity, implying that something is not just dry, but shriveled, withered, or gaunt. It describes a deep structural dryness, often used for dead plants, aged fruit, or a person's physical appearance when they look very thin and frail.

(The withered branch broke easily in my hands.)

Summary
Use ressecado when referring to things that are simply dehydrated or lacking moisture, such as dry skin, lips, or soil. Use ressequido when describing something that is withered, shriveled up, or looking gaunt due to extreme and possibly permanent dryness.
