WHY IT COSTS WHAT IT COSTS

A complete formula, not a bigger percentage

Here is what is in the bottle, and why each part of it is there.

  • 3 FORMS OF VITAMIN ARetinaldehyde + Retinol + Retinyl Palmitate
  • THD VITAMIN CA lipid-soluble vitamin C derivative, built into the formula
  • RECOVERY-MINDED LIPIDSAvocado Oil + Squalane + Vitamin E
  • THE PHILOSOPHYA complete formula — not just a bigger percentage

Stronger is not better.Consistent use without chronic irritation matters more than chasing strength.

One bottle, formulated as the whole retinol step.

THE PRINCIPLE

Stimulate, don't inflame.

Retinol is not the enemy. The mistake is piling unnecessary irritation on top of skin that is already changing with age.

A dose–response curve: results rise with retinoid strength and frequency, peak, then fall away inside a shaded zone where the skin is inflamed rather than stimulated. RESULTSTRENGTH · FREQUENCY  →STIMULATEINFLAME

01

Chasing strength

Higher percentages or more nights do not automatically mean better results.

Diagram: a dial whose needle is pinned past the red mark at the top of the scale.

02

Stacking irritation

Retinoids, acids, scrubs and low-pH vitamin C can become too much for one routine.

Diagram: three overlapping circles, showing active ingredients piled on top of one another.

03

Skipping recovery

Skin needs moisture, lipids and time to recover — not another active every night.

Diagram: a skin barrier drawn as stacked lipid layers — broken and gapped on the left, intact and capped on the right.

RETINOID STRENGTH GUIDE

Stronger is not better

Consistent use without chronic irritation matters more than chasing strength.

GENTLEST

Arrow indicating increasing retinoid strength.
  1. 01 Retinyl Palmitate
  2. 02 Retinol
  3. 03 Retinaldehyde / Retinal

STRONGEST

General guide only; formulation and concentration also matter.

Skin that has been pushed too fast shows four things

  • Persistent redness
  • Burning or stinging
  • Flaking
  • A “windburned” feeling

If these show up: stop adding. Simplify. Reduce frequency.

Irritation is not a scoreboard.

TONIGHT+20 MIN

SCREENSHOT THIS

  1. 01 Icon: a water droplet.

    Cleanse

    Remove makeup, sunscreen and surface debris.

  2. 02 Icon: drying lines.

    Dry skin

    Especially important if you are irritation-prone.

  3. 03 Icon: a pea-size dose.

    Retinoid

    Use a pea-size amount for the face. Follow your prescriber for tretinoin.

  4. 04 Icon: a clock face.

    Wait ~10 minutes

    Give the retinoid a simple, uncluttered window.

  5. 05 Icon: a fine mist.

    Recovery

    Use a recovery mist and/or exosome pads. If using both: mist, then pad. Pads add gentle PHA exfoliation with Korean exosome/EV-style recovery technology.

  6. 06 Icon: a crescent moon.

    Seal + sleep

    Finish with a soothing moisturizer. Add a few drops of face oil as the final step if needed.


THE RETINOL REPORT

store.rajanimd.com · The Retinol Report

Educational only. Follow your prescriber for tretinoin. If pregnant, trying to conceive or breastfeeding, ask your clinician before retinoid use. Use daily broad-spectrum SPF.


NEXT MORNING

Hydrate as needed and use broad-spectrum SPF. UV exposure is one of the biggest drivers of visible photoaging.

THE REST OF THE REPORT

START SLOW

1–2 nights per week is a conservative starting point. Increase only as tolerated. If you get the “windburned” feeling, reduce frequency.

Stronger is not better. Consistent use without chronic irritation matters more than chasing strength.

General guide only; formulation and concentration also matter.

SIGNS YOUR SKIN IS TOO INFLAMED

  • Persistent redness
  • Burning or stinging
  • Tightness
  • Flaking
  • Excess dryness
  • Moisturizer suddenly stings
  • “Windburned” feeling
  • New or increased sensitivity

IF THESE SHOW UP: STOP ADDING. SIMPLIFY. REDUCE FREQUENCY.

Do not use irritation as your scoreboard.

THE INEXPENSIVE RECOVERY STEP

Face oils can be simple, affordable and useful as the final seal.

#1: AVOCADO OIL

The oil I chose inside Retinol A. Rich, emollient and naturally high in fatty acids; a strong pick when skin feels dry or overworked.

OTHER GOOD OPTIONS

  • SUNFLOWER

    Linoleic-rich, lightweight barrier-support option.

  • JOJOBA

    Wax-ester-like feel; balanced and elegant on skin.

  • GRAPESEED

    Lightweight and easy to layer.

  • SWEET ALMOND

    Comforting emollient option for dry-feeling skin.

BUY SMART

  • Cold-pressed
  • Preferably organic
  • Fragrance-free
  • Simple ingredient list

HOW TO USE

After moisturizer, press 2–3 drops over the skin as the final step when you need extra comfort. If acne-prone or very sensitive, patch test first.

WHAT IS CHANGING UNDERNEATH

Your face is already changing underneath the skin. In women, estrogen falls around menopause while collagen, hydration and structural support also change. Retinol itself is not “melting” facial fat. The problem is reacting to hollowing, lines or dryness by adding more strength, more frequency and more actives — then creating inflammation on top of aging skin.

Use mine or use yours. The principle does not change.

STIMULATE. DON'T INFLAME.

Educational only. Follow your prescriber for tretinoin. If pregnant, trying to conceive or breastfeeding, ask your clinician before retinoid use. Use daily broad-spectrum SPF.

BEFORE YOU START

Questions and safety

Tap any question. Everything below is in the report.

01
How often should I start?

1–2 nights per week is a conservative starting point. Increase only as tolerated. If you get the “windburned” feeling, reduce frequency.

02
Is a higher percentage better?

Doubling a percentage does not guarantee double the anti-aging result. Stronger is not better. Consistent use without chronic irritation matters more than chasing strength. General guide only; formulation and concentration also matter.

03
Can I use vitamin C on the same night?

L-ascorbic acid is commonly formulated in an acidic environment, often below about pH 3.5. On already-irritated skin another low-pH step may sting. Retinol A uses THD ascorbate, a lipid-soluble vitamin C derivative, built in.

04
I already use tretinoin. Does this change anything?

Follow your prescriber for tretinoin.

05
What if my skin is already irritated?

If these show up — persistent redness, burning or stinging, flaking, a “windburned” feeling — stop adding. Simplify. Reduce frequency. Do not use irritation as your scoreboard.

Moisture, lipids and recovery are part of the treatment strategy, not a reward for getting through the irritation.

06
I already own a retinol.

Use mine or use yours. The principle does not change. Stimulate, don’t inflame.

What the report argues against is the way most retinol steps get built: one active, chased to a higher percentage, with nothing in the bottle to carry what that costs the skin — so the recovery has to be bought separately, layered on separately, and is the first thing skipped. Retinol A is that whole step in one bottle: three forms of vitamin A, THD vitamin C and recovery-minded lipids. There is no stack to assemble and nothing extra to react to.

07
Where does a face oil go?

After moisturizer, press 2–3 drops over the skin as the final step when you need extra comfort. Look for cold-pressed, preferably organic, fragrance-free, with a simple ingredient list. If acne-prone or very sensitive, patch test first.

08
Sensitive or acne-prone skin?

Patch test first, start at 1–2 nights per week, and increase only as tolerated. Do not stack a retinoid with other irritants on the same night while the skin is settling. If anything on the irritation list above shows up, reduce frequency rather than pushing through it.

09
Pregnant, trying to conceive or breastfeeding?

If pregnant, trying to conceive or breastfeeding, ask your clinician before retinoid use.

The rule under every answer above: stimulate, don’t inflame.

THAT IS THE REPORT

The step it was written about

The actives and the recovery in one formula, so the recovery is not the part that gets skipped.
