Ingredient breakdown

INGREDIENTS

Retinol + Retinyl Propionate Undisclosed %Proven

A dual retinoid system combining pure Retinol with Retinyl Propionate (a vitamin A ester). This proprietary blend delivers anti-aging benefits while minimizing the irritation typically associated with retinol.

  • Clinical Study: A P&G study found 0.3% Retinyl Propionate comparable to 0.02% tretinoin with better tolerability.
  • Mechanism: Stimulates collagen production and accelerates cell turnover to reduce fine lines and wrinkles.
  • Benefit: Visible improvements in wrinkles, texture, and dark spots within 28 days.
Avoid during pregnancy/breastfeeding. Always pair with SPF in the morning.

Niacinamide (Vitamin B3) Undisclosed %Proven

A versatile, well-researched ingredient that brightens skin, strengthens the moisture barrier, and works synergistically with retinol to reduce potential irritation.

  • Research: Studies show niacinamide reduces hyperpigmentation and improves skin elasticity.
  • Synergy: Helps buffer retinol irritation while enhancing overall anti-aging effects.
  • Benefit: Reduces appearance of pores, evens skin tone, and controls oil production.
Well-tolerated by most skin types including sensitive skin.

Palmitoyl Pentapeptide-4 (Matrixyl) Undisclosed %Promising

A signal peptide that stimulates collagen and elastin production. Known as Matrixyl, this peptide helps restore skin firmness and reduces the appearance of wrinkles.

  • Clinical Data: Studies show visible reduction in wrinkle depth after 2-4 months of use.
  • Mechanism: Signals skin cells to produce more collagen without irritation.
  • Benefit: Supports firmer, more elastic skin over time.

Frequently asked questions

FAQ

No, this product is NOT safe during pregnancy or breastfeeding. It contains Retinol and Retinyl Propionate, both vitamin A derivatives (retinoids). Retinoids are associated with potential risks to fetal development and should be avoided during pregnancy and nursing. Consult your healthcare provider for pregnancy-safe skincare alternatives like niacinamide, vitamin C, or azelaic acid.

No, this product is NOT fungal acne safe. It contains Polysorbate 20 and C13-14 Isoparaffin, which are potential triggers for Malassezia (the yeast that causes fungal acne/pityrosporum folliculitis). If you struggle with fungal acne, look for alternatives without these ingredients, such as products with simple silicone or glycerin-based formulas.

This serum already contains retinol, so avoid layering with other retinol products. For vitamin C: Use vitamin C in the morning and this retinol serum at night. For AHAs/BHAs: Alternate nights or use acids in the morning. Combining too many actives can cause irritation. Start slowly and listen to your skin. The niacinamide in this formula is safe to combine with most other ingredients.

This serum works best for oily, combination, and normal skin types. The lightweight, silicone-based formula absorbs quickly without leaving a greasy residue. Those with very dry skin may need to layer with a richer moisturizer. Mature skin will benefit most from the anti-aging ingredients. Sensitive skin can try it but should start with every-other-night application.

You may notice smoother, more hydrated skin immediately upon waking. Visible texture improvement typically appears within 1-2 weeks. Brightening and pore refinement become noticeable around weeks 3-4. For significant wrinkle reduction and anti-aging benefits, consistent use for 4-8 weeks is recommended. Maximum collagen benefits occur after 3+ months of regular use.

Use this serum at night only, after cleansing and toning but before moisturizer. The order is: Cleanser → Toner → This Serum → Eye Cream → Moisturizer. In the morning, skip this serum and apply SPF 30+ instead. Retinol increases sun sensitivity, making sunscreen essential the following day.

This serum has a low comedogenic rating of 1/5. The silicone-based formula (dimethicone) actually creates a breathable barrier that's unlikely to clog pores for most people. Retinol also helps with cell turnover, which can improve pore appearance. However, individual reactions vary, so patch test if you're prone to breakouts.

The product has a 12-month (12M) Period After Opening (PAO). Once opened, use within one year for best efficacy. Retinol can degrade over time when exposed to light and air, which is why Olay uses opaque packaging. Store in a cool, dry place away from direct sunlight. If the color or smell changes significantly, discontinue use.

— Skincarisma verdict
4.3 / 5 ★★★★☆

Verdict: Olay Regenerist Retinol 24 Night Facial Serum is an excellent entry-level retinol for those new to vitamin A derivatives or with sensitive skin. The combination of retinol, retinyl propionate, niacinamide, and peptides delivers visible anti-aging results within 4 weeks with minimal irritation. While the undisclosed retinol concentration and formaldehyde-releasing preservative may concern some, the affordable price point, fragrance-free formula, and proven results make this a solid drugstore choice for tackling fine lines, wrinkles, and uneven texture. Not suitable for pregnancy, breastfeeding, or fungal acne sufferers.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
