The Inkey List
SerumBudgetEvening only
AgingRough TextureSensitive skinDamaged barrier

Stabilised 1% retinoid complex (a blend of retinol and slow-release granactive retinoid) in a squalane base. Budget-priced gentler-than-classical retinol — a reasonable first step into the category.

The Ordinary
SerumBudgetEvening only
AgingRough TextureDark SpotsSensitive skinDamaged barrier

The advanced-strength option in The Ordinary's retinol ladder — oil-based, no water, stable. For users who've already tolerated 0.2% and 0.5% and are ready to escalate. Expect visible purging and dryness in the first 2–4 weeks; pair with a barrier-supporting moisturiser and strict AM SPF.

The verdict

Both contain Retinol. The Inkey List Retinol Anti-Aging Serum adds Retinyl Retinoate. Pick the one whose extra matches what you're treating. The Ordinary Retinol 1% in Squalane is the better fit for dark spots. Both sit in the Budget price tier.
