About The Ordinary and DECIEM
The Ordinary was launched in 2016 by Canadian beauty company DECIEM. The brand's philosophy is quite simple: high-quality, effective formulas, transparent ingredient lists, and accessible prices. This approach created a revolution in the beauty industry.
DECIEM, with its slogan "The Abnormal Beauty Company," chooses to invest in formulation rather than expensive packaging and unnecessary marketing expenses. The Ordinary Retinol 0.5% is a perfect example of this philosophy: minimalist packaging, maximum effect.
The brand's most striking feature is clearly stating active ingredient percentages in each product. This transparency allows consumers to know exactly what they're getting and challenges the "secret formula" approach in the beauty industry.

Why Is Squalane Important?
The Ordinary's choice to formulate retinol in a squalane base is deliberate. Squalane is the stable form of squalene naturally produced by skin and provides these benefits:
- Excellent compatibility: Absorbs very well thanks to its structure similar to skin's natural lipids
- Moisturization: Balances retinol's drying effect, keeping skin soft
- Stability: Prevents retinol from degrading, maintaining formula effectiveness
- Non-comedogenic: Doesn't clog pores, safe for acne-prone skin

Detailed Skin Type Assessment
Normal Skin: Ideal skin type for retinol. The 0.5% concentration is generally well tolerated and provides noticeable results. You can start with 3-4 times weekly use. To determine your skin type, check our Skin Type Guide.
Combination Skin: The squalane base balances both oily and dry areas. Provides light effect for T-zone, nourishing for cheeks. Apply a thin layer to entire face for best results.
Dry Skin: Squalane's moisturizing effect is a big advantage, but additional moisturizer may be needed. Retinol may increase dryness initially, so support with rich moisturizer.
Oily Skin: Use with caution. Oil-based formula may feel heavy on oily skin. Consider water-based retinol or retinoid formulas as alternatives.
Sensitive Skin: Not recommended. The 0.5% concentration is too strong for sensitive skin. The Ordinary's 0.2% version or encapsulated retinol formulas may be more suitable.
Pregnancy and Breastfeeding Warning
Retinol must absolutely not be used during pregnancy and breastfeeding. Vitamin A derivatives are known to have potential teratogenic effects on the fetus during this period. If planning pregnancy, it's recommended to stop use at least 1 month before.
How to Use
Expert Opinion
— Dr. Ayse Demir, DermatologistThe most important rule in retinol use is being "slow and steady." Using high doses without acclimating your skin can lead to irritation, redness, and flaking. This condition known as "retinoid dermatitis" doesn't mean the product isn't working; it shows your skin is in the adaptation process.
Step-by-Step Usage Guide
1. Prepare Skin Cleanse your face with a gentle cleanser. Ensure skin is completely dry - applying to wet skin can increase penetration and cause irritation.
2. Take Appropriate Amount 3-4 drops of serum (approximately a pea size) is sufficient. More is not better, it actually increases irritation risk.
3. Spread Gently Spread gently on face and neck area with fingertips. Avoid or be very careful around eye area.
4. Wait to Dry Wait 5-10 minutes for absorption. This time allows retinol to interact with skin.
5. Moisturize Support with a rich moisturizer. This both provides hydration and "locks in" retinol.
Sandwich Method
If you're new to retinol or have sensitive skin, try the "sandwich" method: Moisturizer, Retinol, Moisturizer. This technique increases tolerance by softening retinol's contact with skin.
Usage Frequency Guide
| Experience Level | Weekly Use | Notes |
|---|---|---|
| Beginning (1-4 weeks) | 1-2 times weekly | Monday and Thursday |
| Adaptation (5-8 weeks) | 2-3 times weekly | Use every other day |
| Maintenance (8+ weeks) | 3-4 times weekly | Increase based on skin tolerance |
| Advanced | Every night | Only if full tolerance achieved |
When Should It Be Used?
Retinol Is Only Used at Night
Retinol degrades in sunlight and makes skin more sensitive to UV damage. Therefore, use ONLY in your evening routine. In the morning, be sure to apply SPF 30 or higher sunscreen - this rule applies even on cloudy days.
Ingredients Not to Use Together
Caution: Ingredient Interactions
When used with certain active ingredients, retinol can cause serious irritation and sensitivity:
- Vitamin C (L-Ascorbic Acid): Use Vitamin C in morning, Retinol at night. You can find the best products in our Vitamin C Serum Review
- AHA/BHA Acids: Don't use same night, apply on alternate days. Check our Glycolic Acid (AHA) and Salicylic Acid (BHA) guides
- Benzoyl Peroxide: Neutralizes retinol
- Bakuchiol: Actually can be used together, may increase tolerance
- Niacinamide: Can be safely used together
Safe Combinations
Ingredients you can safely use with retinol:
- Hyaluronic acid (moisturization)
- Ceramides (barrier support)
- Peptides (anti-aging synergy)
- Niacinamide (skin tone evening)

Frequently Asked Questions
At what age should retinol use begin?
Generally, can be started from age 25 for preventive purposes. However, if early aging signs exist, starting with low dose in early 20s is also possible.
Can The Ordinary Retinol 0.5% be used every day?
Not immediately. After your skin adapts (usually 8-12 weeks), you can use every night. Start with 1-2 times weekly initially.
Does retinol thin my skin?
No, this is a common myth. Retinol actually thickens skin - it renews the epidermis layer and strengthens dermis by increasing collagen production.
Can it be applied under eyes?
The Ordinary Retinol 0.5% is not formulated for eye area. Special retinol eye creams or lower concentration products should be preferred for eye area.
How long until I see results?
First improvements begin to appear in 4-6 weeks. Optimal results require more than 12 weeks of regular use.
Does retinol remove sun spots?
Yes, retinol helps fade spots by accelerating cell turnover. However, sunscreen use is essential for best results, otherwise new spots may form.
How do I know if The Ordinary Retinol has gone bad?
When retinol oxidizes, it changes color from yellow to brown. If the serum, which was light yellow/clear when opened, has taken on a dark color, it has lost its effectiveness.
Can I wear makeup with retinol?
Since retinol is used at night, there's no barrier to wearing makeup in the morning. You can proceed to makeup after applying your SPF daily skincare in the morning.
Conclusion and Rating
The Ordinary Retinol 0.5% in Squalane is a budget-friendly but highly effective anti-aging serum. Thanks to the squalane base, it's more tolerable than other retinol formulas and its drying effect is reduced.

|---|---|
| Efficacy | 4.5 |
| Price/Performance | 5.0 |

Final Words
If you're ready to take the next step in your retinol journey and looking for a budget-friendly solution, The Ordinary Retinol 0.5% in Squalane is an excellent choice. With realistic expectations, patient use, and sun protection, you'll see noticeable improvements in your skin quality.
However, if you're completely new to retinol, I recommend starting with the 0.2% version first or preparing your skin with a gentler formula like Granactive Retinoid.
