A powerful day-to-night duo—Firming Plant Peptide Serum to help hydrate and firm and Nightly Retinol Serum to visibly smooth and refine.

Traditional retinol serums can be overly harsh, often causing dryness or irritation. Oak’s Nightly Retinol Serum was designed to be gentle yet highly effective—featuring a natural retinol derivative called Retinyl Linoleate that helps smooth skin texture and visibly soften fine lines with zero downtime. The formula also features Sodium Hyaluronate (a form of Hyaluronic Acid) for deep hydration and plumping, Squalane to help prevent moisture loss, and Avocado Fruit Extract for a soft, nourished finish. Use nightly to wake up to skin that looks firmer, smoother, and more radiant over time.

The Benefits:

  • Helps visibly soften fine lines and smooth uneven texture.
  • Formulated for consistent nightly use without irritation or downtime.
  • Helps hydrate as it works for a soft, nourished complexion.
  • Leaves skin looking firm with a healthy glow.

Full Size Nightly Retinol Serum: 30 ml | 1 fl oz

Use PM daily. Apply a dime-size amount to clean, dry skin, avoiding the eye area. Let the serum soak in, then follow with Ritual Oil and Moisture Rich Balm to lock in moisture. Apply SPF in the morning.
TIP: Apply to the décolleté and neck to help smooth the appearance of fine lines and wrinkles. Apply SPF in the morning.

Key Ingredients:

  • Retinyl Linoleate: Helps soften the look of fine lines and smooth texture.

FAQs FAQ

FAQs

  • Nightly Retinol Serum should be applied to clean, dry skin in the evening—after a toner if you use one, and before moisturizer. Allow the serum to fully absorb for 2–5 minutes before layering additional products. 

  • Nightly Retinol Serum helps support increased cellular turnover—which can visibly reduce signs of aging by smoothing the look of fine lines, wrinkles, and uneven texture. Your skin should be left with a soft, healthy-looking glow.  

  • Nightly Retinol Serum is formulated with Retinyl Linoleate, a gentle form of retinol, and buffered with nourishing, barrier-supporting ingredients to help minimize skin disruption. For sensitive skin, we recommend patch testing first and starting with 1–2 applications per week to see how your skin responds. And as with any Retinol treatment, we recommend using SPF daily as Retinol may increase sun sensitivity. 

  • All Oak formulas are designed to deliver visible results almost immediately and compounding results over time. In a consumer performance study of 25 participants ages 28 to 74 using Nightly Retinol Serum once daily, 100% said their skin appeared brighter and more radiant after 7 weeks. 96% also said their skin looked firmer and felt softer and smoother after 7 weeks. 

  • Nightly Retinol Serum is an evening-specific serum that helps smooth texture, promote a more even tone, and soften the look of fine lines. Daily Vitamin C Serum is a morning-specific serum that helps fade dark spots, improve the appearance of photodamage, and leave skin looking brighter and healthier. Firming Plant Peptide Serum is an AM or PM serum that helps support aging skin by visibly plumping, firming, and hydrating. And yes—you can layer Nightly Retinol Serum with Firming Plant Peptide Serum in your evening routine. Just apply Firming Plant Peptide Serum first, let it absorb for 2–5 minutes, then follow with Nightly Retinol Serum.
