Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum vs The Ordinary Retinol 1% in Squalane
Both serums contain Retinol, but each adds something the other doesn't. Here's where they overlap and where they split.
A micro-dosed retinol serum with ceramide and peptide support designed for daily use with less irritation. A gentle daily-retinol approach for those who can't tolerate higher strengths; gradual, cumulative results.
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.
Which should you choose?
Both contain Retinol. Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum adds Peptides. Pick the one whose extra matches what you're treating. Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum is the better fit for fine lines and preventing sun damage; The Ordinary Retinol 1% in Squalane for signs of aging and dark spots. On price, The Ordinary Retinol 1% in Squalane is the less expensive option (Budget versus Premium).
