Discover why Vitamin A is the versatile ingredient that your skincare regimen has been missing!

Let's get straight to the point: Vitamin A stands out as the most cherished hero ingredient across dermatology. Feeling perplexed because it doesn't ring a bell? Chances are, you're familiar with retinol or retinoids, correct? They're essentially synonymous; retinoids represent the active form of vitamin A. Vitamin A graces the ingredient lists of numerous anti-aging serums and facial oils.


CATEGORY: Retinoid

KEY BENEFITS: Promotes collagen production, enhances cell turnover, reduces oil production, exhibits anti-inflammatory properties.

IDEAL USERS: Individuals starting from their mid-20s (or even earlier for those combating acne), except for pregnant or breastfeeding women. However, individuals with sensitive skin should exercise caution depending on the formulation, as vitamin A may potentially cause irritation.

USAGE FREQUENCY: Daily, specifically at night, once your skin becomes accustomed to the ingredient.

COMPLEMENTARY INGREDIENTS: Always incorporate sunscreen alongside vitamin A due to its heightened sun sensitivity. Many formulations blend soothing components such as chamomile or hydrating ingredients like hyaluronic acid with vitamin A to enhance product tolerance.

AVOID COMBINING WITH: While alpha-hydroxy acids, such as glycolic acid, complement vitamin A's anti-aging effects, using them simultaneously may increase the risk of irritation.

What Is Vitamin A?

Vitamin A, according to the National Institute of Health, encompasses a group of retinoids. Thus, let's consider the terms interchangeably. Retinoids represent three distinct states of vitamin A: retinol, retinal (or retinaldehyde), and retinoic acid. They offer similar skincare benefits, differing primarily in their conversion process within the skin and subsequent potency. Retinoic acid, present in prescription-strength products, boasts the highest potency, while retinols rank as the mildest, with retinaldehyde falling in between.

Skin Benefits of Vitamin A

The benefits are extensive, vitamin A has undergone more extensive skincare studies than any other ingredient. Its use in dermatology dates back to 1943, making it a tried-and-tested ingredient with a plethora of proven advantages. Some notable benefits include:

  • Accelerates skin cell turnover: Vitamin A facilitates the shedding of old skin cells and promotes the regeneration of newer, healthier, and smoother cells, as outlined by Chen.

  • Enhances skin texture and tone: Acting as an exfoliant, vitamin A improves both skin tone, particularly beneficial for hyperpigmentation, and surface texture.

  • Stimulates collagen production: Vitamin A not only works on the surface layer but also penetrates the deeper dermal layer to stimulate collagen production.

  • Diminishes fine lines and wrinkles: Vitamin A aids in reducing fine lines, wrinkles, and thickening the skin while minimizing the breakdown of existing collagen and elastin.

  • Effectively treats acne: Prescription-strength vitamin A, or retinoic acid, has FDA approval for acne treatment due to its ability to regulate oil production and prevent pore blockages.

  • Addresses post-inflammatory hyperpigmentation: Vitamin A can minimize post-blemish discoloration and exhibits anti-inflammatory properties, reducing redness.

Side Effects of Vitamin A

Despite its potent effects, vitamin A may pose potential side effects such as irritation, dryness, and photosensitivity. Over-the-counter retinoids typically entail reduced likelihood and intensity of side effects compared to prescription-strength variants. These effects usually subside as the skin acclimates to the ingredient, a process termed retinization.

How to Use Vitamin A

Exercise caution and initiate usage gradually. Excess vitamin A usage may escalate irritation, prompting discontinuation. Commence with usage every third night, gradually progressing to every other night and eventually nightly application. Apply a minimal amount—roughly pea-sized—on clean skin, ensuring the incorporation of gentle and mild products in your routine until skin tolerance is established.

Patience is essential, noticeable skin improvements typically require a minimum of eight to 12 weeks.


How frequently can vitamin A be used?

Adopt a gradual approach with vitamin A usage, starting once every three days, then progressing to every other day, and finally daily as skin tolerance develops.

Is vitamin A suitable for sensitive skin? Given its potential for irritation, individuals with sensitive skin should introduce vitamin A cautiously. Begin with low-concentration products or formulations enriched with skin-calming ingredients like chamomile, aloe, or green tea extract.

Are vitamin A and retinol synonymous?

Consider vitamin A as the overarching term encompassing "retinoids." Within this category, three vitamin A versions exist, including retinal—the ingredient found in prescription-strength formulations—retinoic acid, and retinol, the mildest among the three.
