The Ordinary is popular for one main reason: it sells ingredient-focused formulas at prices that make “trial and error” less painful. The downside is that the lineup can feel like a chemistry shelf—lots of acids, retinoids, peptides, and similar-looking bottles. This guide reviews standout picks in plain English and explains how to choose the right products for your goals and skin type.

How to shop The Ordinary without overbuying

  • Pick one primary goal (acne, texture, dark spots, dehydration, redness, aging) and start with 1–2 actives max.
  • Respect irritation risk: acids + retinoids + strong vitamin C in the same routine is a common mistake. Build slowly.
  • Give it time: most “results” take 6–12 weeks (pigmentation often longer). Switching products weekly can backfire.
  • Don’t skip sunscreen: many actives increase sun sensitivity, and UV exposure reverses progress on dark spots and texture.

27 excellent The Ordinary products (grouped by what they do)

Note: The “best” product depends on your skin. Think of this as a curated map of what’s worth considering and why.

1) Cleansers & easy first steps

  • Squalane Cleanser – A gentle, non-stripping cleanser that’s especially comfortable for normal-to-dry or easily irritated skin.
  • Glucoside Foaming Cleanser – A light foaming option that can suit combination or oilier skin without feeling harsh.
  • Hyaluronic Acid 2% + B5 – A hydration layer that helps skin feel less tight; apply to damp skin and seal with moisturizer.

2) Barrier support & calming (for dryness, sensitivity, redness)

  • Niacinamide 10% + Zinc 1% – Helps regulate oil and the look of pores; can be a little strong for very sensitive skin, so patch test.
  • Amino Acids + B5 – Lightweight hydration that can be a good alternative if hyaluronic acid feels sticky or pills.
  • Soothing & Support Barrier Serum – A more “comfort-first” option when skin feels stressed from weather, over-exfoliation, or new actives.
  • Natural Moisturizing Factors + HA – A straightforward, no-frills moisturizer that pairs well with most actives.
  • 100% Plant-Derived Squalane – A simple, skin-identical-feeling oil for sealing moisture; useful when skin is dry or compromised.
  • Rose Hip Seed Oil – A richer oil option some people like for dryness and visible dullness (results vary; patch test if acne-prone).

3) Exfoliation & texture (dullness, roughness, clogged pores)

  • Glycolic Acid 7% Toning Solution – A strong AHA toner for improving the look of texture and brightness; overuse can irritate.
  • Lactic Acid 5% – A gentler AHA option for beginners who want smoother-feeling skin with less sting risk.
  • Lactic Acid 10% – A step up for experienced users who tolerate acids well and want more noticeable smoothing.
  • Mandelic Acid 10% – Often tolerated better by sensitive skin; a slower, gentler exfoliating approach.
  • Salicylic Acid 2% Solution – A BHA that targets oil and congestion; best for blackheads, breakouts, and oily areas.
  • Azelaic Acid Suspension 10% – A multitasker for uneven tone, redness-prone skin, and texture; can feel siliconey but layers well.

4) Dark spots & uneven tone (hyperpigmentation, post-acne marks)

  • Alpha Arbutin 2% + HA – A spot-focused brightening serum that pairs well with sunscreen and patience.
  • Tranexamic Acid 5% – Often chosen for stubborn discoloration and uneven tone; keep routine gentle to avoid rebound irritation.
  • Vitamin C Suspension (water-free) – Potent brightening; can tingle and feel gritty. Best for tolerant skin and simple routines.
  • Ethylated Ascorbic Acid 15% – A more elegant vitamin C option for many users, balancing potency with wearability.

5) Anti-aging & firming (lines, loss of bounce, overall refinement)

  • Granactive Retinoid (emulsion or squalane) – A gentler entry to retinoid benefits; start 2–3 nights/week.
  • Retinol in Squalane – A classic retinol approach with an oily base; can be effective but more irritation-prone for some.
  • “Buffet” (multi-peptide serum) – A hydrating peptide blend aimed at overall smoothing and resilience; good for routine “support.”
  • Matrixyl 10% + HA – Peptide-focused serum commonly used for a plumper, smoother look over time.
  • Argireline Solution 10% – Used around expression lines (forehead/crow’s feet); subtle results, best viewed as a “finishing” step.

6) Eyes & targeted concerns

  • Caffeine Solution 5% + EGCG – Helps the look of puffiness and under-eye darkness for some; results depend on the cause of circles.
  • Multi-Peptide Eye Serum – A gentler, hydration-plus approach to the eye area for those who want firmness support.

7) Masks/peels (use with caution)

  • AHA 30% + BHA 2% Peeling Solution – A powerful weekly peel for experienced users only; avoid if sensitive, barrier-impaired, or new to acids.
  • Salicylic Acid 2% Masque – A wash-off option for oily or congested skin that can feel less committing than a leave-on BHA.

What to buy first: simple routines by skin goal

Option A: Oily/acne-prone (minimal but effective)

  • Cleanser (Glucoside Foaming)
  • Niacinamide (AM or PM)
  • Salicylic Acid 2% (PM, 2–4 nights/week)
  • Moisturizer + sunscreen (AM)

Option B: Dry/sensitive (barrier-first)

  • Squalane Cleanser
  • Soothing/Barrier serum or Amino Acids + B5
  • Natural Moisturizing Factors + HA
  • Squalane oil as needed

Option C: Dark spots (slow and steady)

  • Gentle cleanser
  • Alpha Arbutin or Tranexamic Acid (AM or PM)
  • Azelaic Acid (PM or alternate nights)
  • Daily sunscreen (non-negotiable)

Option D: Anti-aging beginner

  • Gentle cleanser
  • Peptide serum (AM)
  • Granactive Retinoid or Retinol (PM, start 2 nights/week)
  • Moisturizer + sunscreen (AM)

Mixing rules (to reduce irritation)

  • Don’t stack too many actives: choose either an exfoliating acid or a retinoid for the same night at first.
  • Go slow: increase frequency only when skin feels calm (no burning, persistent redness, or flaking).
  • Patch test if you’re prone to reactions, and introduce one new product at a time.
  • SPF daily, especially with acids, retinoids, and vitamin C.

Bottom line

The Ordinary makes it easy to build an effective routine on a budget—but the best results come from choosing a small set of compatible products, using them consistently, and prioritizing barrier health. If you’re unsure where to start, pick one goal, one active, and a dependable moisturizer and sunscreen, then adjust after a few weeks based on how your skin responds.
