Retinol vs. Retinal vs. NAD+ for Mature Skin: A K-Beauty Guide highlighting popular Korean skincare products.

Retinol vs. Retinal vs. NAD+ for Mature Skin: A K-Beauty Guide

Retinol, retinal and NAD+ are three different ingredients, not a ranking. None of them is a miracle, and none of them replaces a moisturizer or sunscreen. Think of this as an ingredient map rather than a best-of list: once you know which lane a product sits in, choosing gets much easier.

Quick Answer

  • Retinol suits goals around fine lines, dullness and the look of firmness on the face. Face-serum lane.
  • Retinal suits goals around fine lines, dryness and tired-looking under-eyes. Eye-area lane.
  • NAD+ suits goals around fine lines, wrinkles and the look of firmness, used in an essence step.

These can be combined, but go slowly, follow each product's directions, and don't stack them hoping for faster results. Faster is not how skincare works.

Why This Even Comes Up for Mature Skin

Mayo Clinic describes wrinkles as a normal part of aging, and the American Academy of Dermatology notes that menopause-related changes can bring dryness, thinning and changes in collagen.

A K-beauty routine won't treat a medical condition. What it can do is support hydration, a dewy finish, and the appearance of fine lines, firmness and dullness. That distinction matters, because it sets honest expectations before you spend anything.

It also means the unglamorous steps carry more weight than the active does. A RIMAN ICD Dermatology Cream ($66.00) or a COSRX Hyaluronic Acid Intensive Cream ($17.50) will do more for dry, thin-feeling skin than adding a third active.

What Retinol Is For in K-Beauty

Retinol is a vitamin A ingredient, and in K-beauty it usually sits in the face-serum lane.

Our pick: the ANUA Retinol 0.3% + Niacin Renewing Serum ($25.00, 30 ml), which pairs retinol with niacinamide.

Its directions are worth reading closely, because they build in a tolerance ramp most people skip:

  • Evening use. After cleansing and toning, apply "a very small amount (less than a pea-size)" and gently pat over the face, avoiding the eye and lip areas
  • "Follow immediately with moisturizer"
  • "First two weeks: use once every two days to allow skin to build tolerance"
  • "Progress to every other day, then nightly as skin adapts over 4–6 weeks"
  • "Always apply broad-spectrum SPF the following morning"
  • Not for use during pregnancy or nursing

That last-but-one line isn't optional. If you're starting retinol, a daily RIMAN ICD Moisture Layer Sunscreen ($39.00, SPF 50+ PA+++) is part of the routine, not an upsell.

What not to expect: retinol won't erase wrinkles, won't guarantee a transformation, and isn't medical treatment.

What Retinal Is For in K-Beauty

Retinal is also a vitamin A ingredient. Here it's positioned as a targeted eye-area product rather than an all-over serum.

Our pick: the BEAUTY OF JOSEON Revive Eye Serum: Ginseng Retinal ($21.50, 30 ml). Ginseng supports hydration; the retinal supports the look of fine lines around the eyes.

Directions: "Pump the applicator 1 to 2 times," then "using your ring finger, gently pat the serum under the eyes and around the eye area." Evening only, and "always follow with a broad-spectrum SPF in the morning."

If you'd rather have a cream texture than a serum in that spot, the DR. MELAXIN Eyephalt Retinal Eyebag Cream ($34.50) is the other retinal option we carry. Follow the directions on the packaging you receive and introduce it on its own rather than alongside another new active.

What not to expect: an eye serum is not a neck treatment, and there's no guaranteed timeline for crow's feet.

What NAD+ Is For in K-Beauty

NAD+ is the odd one out here: not a vitamin A derivative at all, but a separate ingredient category. In K-beauty it generally shows up in an essence step.

Option 1: a dedicated NAD+ essence

The NUMBUZIN No.9 NAD+ BIO Lifting-sil Essence ($24.50, 50 ml) has an elastic, thread-like texture and a peptide complex.

Directions: "Apply an appropriate amount over the entire face and gently pat until absorbed." For concern areas such as the forehead, frown lines and smile lines, the page says to layer an extra amount and massage gently. "Use morning and evening… followed by moisturizer," with sunscreen as the final morning step.

On the name: "Lifting" here is cosmetic naming, not a medical lift. The brand reports its own clinical results and notes that individual results may vary — worth reading as the brand's figures rather than independent evidence, and there's no four-week promise we'd make on its behalf.

Option 2: an NAD+ precursor, inside a treatment duo

Here's the part most NAD+ guides miss. You don't have to buy a product with "NAD+" on the front to be in this lane.

The RIMAN ICD Dermatology First Package ($99.00 — Booster EX 130 ml plus Serum EX 45 ml) lists NMN (Nicotinamide Mononucleotide) among its key ingredients, and its page describes NMN as "the direct precursor to NAD+." Same pathway, different position on it: one product supplies NAD+ itself, the other supplies the molecule the skin builds it from.

The format is different too. Instead of a single essence, it's RIMAN's Boo-Se-Boo method — Booster, then Serum, then Booster again, finished with the RIMAN ICD Dermatology Cream. It's layered hydration with the treatment in the middle, which suits dry, mature skin that finds one heavy step uncomfortable.

Which to choose comes down to budget and routine shape. The numbuzin essence is one bottle at $24.50 that slots into the routine you already have. The RIMAN duo is $99.00 and asks you to adopt a sequence. Neither is better in the abstract.

Retinol vs. Retinal vs. NAD+ Comparison

Ingredient Main cosmetic purpose Best for if you want Live pick on BestSkincareUSA.com Routine step What not to expect
Retinol Appearance of fine lines, texture and dullness A face-wide active with a tolerance ramp ANUA Retinol 0.3% + Niacin Renewing Serum — $25.00 Evening face serum Erased wrinkles; a guaranteed timeline
Retinal Appearance of fine lines around the eyes Something targeted for tired-looking under-eyes BEAUTY OF JOSEON Revive Eye Serum: Ginseng Retinal — $21.50 Evening eye step A neck treatment; removal of eye bags
NAD+ Appearance of fine lines and firmness A single essence that drops into your current routine NUMBUZIN No.9 NAD+ BIO Lifting-sil Essence — $24.50 Essence, before serum and moisturizer A medical lift; a four-week promise
NMN (NAD+ precursor) Layered hydration with a treatment step A full sequence rather than one bottle RIMAN ICD Dermatology First Package — $99.00 Booster → Serum → Booster, then cream A substitute for moisturizer or sunscreen

Which One Is Better for Mature Skin?

There's no single winner, and anyone who names one is selling something. The choice follows the goal:

  • Face concerns — fine lines, dullness, texture → retinol
  • Under-eye dryness and tiredness → retinal
  • Firmness in an essence step → NAD+ or the NMN route

One thing that's true across all of them: dry, thin-feeling skin still needs hydration and a barrier-supporting cream. Vitamin A products are not moisturizers.

For that step: the RIMAN ICD Dermatology Cream ($66.00) or the richer RIMAN ICD Radiansome 100 Microfluidizer Cream ($103.60) at the premium end; the COSRX Hyaluronic Acid Intensive Cream ($17.50), COSRX Advanced Snail 92 All in One Cream ($19.00), ANUA Birch 70 Moisture Boosting Cream ($30.00) or BIODANCE Skin Glow Essence Cream ($29.00) if you want to spend less.

Can You Combine Retinol, Retinal and NAD+?

Each of these does a different job in the routine, so in principle they can coexist. In practice, how you introduce them decides whether it works.

  • Don't start everything on night one
  • Introduce one product at a time, so you can tell what's responsible for what
  • Follow each product's own directions — the ANUA retinol serum has a two-week ramp built in for a reason
  • Use daytime sunscreen whenever vitamin A is in your routine
  • Don't stack products hoping for faster results
  • If skin feels dry or tight, reduce frequency and lean on your moisturizer

What Not to Do

  • Don't start every active at once
  • Don't use more product than directed — more is not faster
  • Don't skip moisturizer or sunscreen
  • Don't read product names as medical claims. "Lifting" is a texture and a marketing word, not a procedure
  • Don't chase before-and-after timelines you've seen online

Final Thought

Retinol, retinal and NAD+ are three distinct K-beauty options for mature-skin goals, and NMN gives you a fourth way into the same lane. Pick the one that matches what's actually bothering you, follow its directions, keep your moisturizer and sunscreen in place, and give it time without fixating on a timeline.

Frequently Asked Questions

What is the difference between retinol and retinal?

Both are vitamin A ingredients. In the products we carry, retinol sits in a face-serum lane — the ANUA Retinol 0.3% + Niacin Renewing Serum is applied over the whole face — while retinal shows up in targeted eye products like the BEAUTY OF JOSEON Revive Eye Serum: Ginseng Retinal. Follow each product's own directions rather than treating them as interchangeable.

Is retinol or retinal better for mature skin?

Neither is better in the abstract — they're aimed at different areas. If your concern is across the face, retinol. If it's the under-eye area specifically, retinal. If your skin is dry or easily irritated, the gentler route is one active, introduced slowly, with a good moisturizer behind it.

What is NAD+ in Korean skincare?

NAD+ is a coenzyme, and in K-beauty it appears as an ingredient category separate from vitamin A — usually in an essence step, as in the NUMBUZIN No.9 NAD+ BIO Lifting-sil Essence. You'll also see NMN, which the RIMAN ICD Dermatology First Package page describes as a direct precursor to NAD+.

Can I use retinol and retinal together?

They can coexist, but not starting on the same night. Introduce one, let your skin settle, then add the other — and keep them in their own zones, face serum versus eye area. Daily sunscreen the following morning either way.

Can I use NAD+ with retinol?

Generally yes, since they're different ingredient categories doing different jobs — the essence sits earlier in the routine and the retinol later. Still introduce one at a time, follow both sets of directions, and cut back if skin feels tight.

Which product should I start with?

Start with whichever matches your main concern, and only one. If you can't choose, start with the step that isn't an active at all: a barrier-supporting moisturizer and daily sunscreen do more for mature skin than a third serum.

Do these products remove wrinkles?

No. These are cosmetic products that may support the appearance of fine lines, firmness and dullness. They don't remove wrinkles, and any product promising that is overpromising.

Do I need sunscreen with retinol or retinal?

Yes. Both product pages say so explicitly — "always apply broad-spectrum SPF the following morning." The RIMAN ICD Moisture Layer Sunscreen is SPF 50+ PA+++ broad spectrum, and it's the step that protects whatever else you're doing.
