Bottom line
If your skin tolerates retinoids, Olay Retinol24 offers a convenient fragrance-free night moisturizer with two vitamin A derivatives. Its Mid-Range value depends on routine simplicity rather than known retinol strength.
If you want a fragrance-free night retinoid without adding a separate serum, Olay Regenerist Retinol24 Night Moisturizer combines retinol and retinyl propionate with niacinamide, glycerin and peptides. Its leave-on format supports a plausible route to gradual improvement in skin texture and fine lines, although Olay does not disclose retinoid percentages.
What it claims
Olay says Retinol24 smooths and brightens skin starting on day one, improves fine lines and wrinkles, dark spots, elasticity, pores, and texture, and provides 24-hour hydration. The brand also says skin transforms in four weeks and reports that 8 out of 10 users agreed that Retinol24 reduced fine lines and wrinkles in four weeks.[1]
The current page also promotes twice the retinoid penetration versus a top-selling drugstore brand based on a skin-penetration study. That is a brand-reported delivery comparison, not evidence that this moisturizer produces twice the clinical wrinkle or pigmentation improvement.[1]
Claims vs. formula
The leave-on retinoid system gives the formula a credible basis for gradual improvement in fine lines, texture, pigmentation, and overall photoaged appearance. A systematic review of over-the-counter vitamin A cosmetics found that some retinol products produced visible improvement, but the evidence base varied substantially by concentration, formulation, study design, and finished product.[2] Because Olay keeps the exact retinoid strength proprietary, those broader retinol findings cannot establish the exact potency or timeline of Retinol24.
Retinyl propionate adds a second vitamin A derivative, while niacinamide, palmitoyl dipeptide-7, palmitoyl pentapeptide-4, tripeptide-3, and carnosine broaden the tone, elasticity, and wrinkle-support story. Ingredient presence supports plausibility, but the finished-product claims still stand on Olay’s own testing rather than on those ingredients alone.
The moisturizing side is straightforward. Glycerin, dimethicone, dimethicone crosspolymer, dimethiconol, and related texture agents give the cream hydration, slip, and a cushioning layer that helps the product function as both treatment and night moisturizer.[1]
Ingredients that matter
Retinol supplies the main retinoid treatment pathway, while retinyl propionate adds a second vitamin A derivative. Niacinamide, glycerin and a silicone-based cream help condition skin during retinoid use. Palmitoyl Pentapeptide-4 and other peptides support the formula’s wrinkle positioning without replacing the retinoids as the better-established active ingredients.
Retinol
Retinol is a well-supported over-the-counter retinoid for fine lines and rough texture, with some benefit for uneven tone. Stability, vehicle, strength, and tolerability matter more than chasing the highest percentage.

Niacinamide
If your skin feels dry or uncomfortable, niacinamide can support hydration and reduce water loss in a well-formulated product. It also has evidence for uneven tone and visible oiliness, but…

Glycerin
If your skin feels dry or tight, glycerin helps your skin hold moisture. You don't need a high percentage or a separate serum when your moisturizer already works well.
Read the IngredientBriefSafety and regulatory context
Retinol can cause dryness, peeling, redness, or irritation, especially when first introduced. The American Academy of Dermatology recommends starting retinoids slowly, using moisturizer to improve tolerance, and wearing daytime sun protection because retinoids can increase sun sensitivity.[3]
Olay directs nightly use and specifically says to apply SPF the following morning. The moisturizer format does not eliminate retinoid irritation risk, so frequency still needs to match your skin’s tolerance.[1]
What to expect in the short term
Expect a light, smooth cream with substantial silicone slip and no added fragrance. Hydration and surface smoothness can show up before slower retinoid-driven changes, while sensitive or retinoid-naive skin may need a slower introduction rather than nightly use from the start.
What to expect over time
The more realistic treatment window is weeks rather than days. Olay’s day-14 and day-28 messaging gives you brand-specific milestones, but the exact pace will depend on retinoid strength, formulation, consistency, and tolerance. The undisclosed percentages make it impossible to compare potency precisely with a disclosed-retinol product.
Dark-spot, firmness, and wrinkle improvements are plausible within the overall formula, but BB does not translate Olay’s penetration result or staged timelines into guaranteed clinical superiority over other retinol moisturizers.
Who it fits
If your skin is dry, normal or oily and you want one combined retinoid night cream, Olay lists those skin types among its intended users. Introduce it gradually if you have not used retinoids before; dryness, peeling and stinging remain possible. The brand’s dermatologist-endorsement language does not establish product-specific dermatologist testing.
Compare before you buy
At the Mid-Range tier, the value is strongest if this replaces both a basic night moisturizer and a separate retinoid step. The formula gives you retinol, retinyl propionate, niacinamide, peptides, carnosine, and hydration support in one fragrance-free cream. If exact retinol strength matters to your buying decision, a disclosed-percentage alternative gives you more direct potency comparison.
Final Assessment
If your skin tolerates retinoids, Olay Retinol24 offers a convenient fragrance-free leave-on formula with two vitamin A derivatives and moisturizing support. Their exact strengths are undisclosed, limiting potency comparisons with other treatments. The Mid-Range value is strongest when one cream replaces a separate retinoid and moisturizer.
