Collection: Skin Care Products Containing Zinc PCA

What is Zinc PCA?

Zinc PCA (zinc pyrrolidone carboxylic acid) is an advanced-generation active ingredient formed by the combination of the mineral zinc and PCA (pyrrolidone carboxylic acid), one of the skin's natural moisturizing factors. It is considered the most effective form of zinc used in skincare—possessing up to 30% higher absorption capacity compared to zinc oxide or zinc sulfate.

This superior absorption makes Zinc PCA the gold standard, especially for sebum control and acne care. While the zinc component provides antibacterial and anti-inflammatory effects, the PCA component supports the skin's moisture-retention capacity. Thanks to this dual mechanism, Zinc PCA balances oil levels without drying out the skin—completely eliminating the dryness issues that are the greatest disadvantage of traditional zinc forms.

The NewLab Skincare Products Containing Zinc PCA

Niacinamide 10% + Zinc 1% — Anti-Acne Pore Tightening Face Serum

This serum from The NewLab is one of the essential products for anti-acne care with its combination of 10% Niacinamide and 1% Zinc PCA. While Niacinamide strengthens the skin barrier, supports collagen production, and reduces the appearance of pores, Zinc PCA reaches the sebaceous glands directly to control excess oil production at the source. Panthenol in the formula moisturizes and soothes the skin, Allantoin supports skin repair, and Lactic Acid provides gentle exfoliation to improve skin texture.

Ingredients: Aqua, Niacinamide, Pentylene Glycol, Panthenol, Zinc PCA, Allantoin, Hydroxyethylcellulose, Polysorbate 20, Lactic Acid, Ethylhexylglycerin, Phenoxyethanol, Tetrasodium EDTA

Skin Type: Suitable for oily, combination, acne-prone, and normal skin. It does not make the skin sensitive to the sun—it can be used in all four seasons.

How Does Zinc PCA Work? Sebum Regulation Mechanism

Understanding the mechanism of action of Zinc PCA explains why it is so effective:

1. Direct Reach to Sebaceous Glands: While traditional forms of zinc (zinc oxide, zinc sulfate) remain on the skin to form a barrier, Zinc PCA penetrates the skin to reach the sebaceous glands (oil glands) directly. This "inside-out" approach controls oil production at the source.

2. Balancing Sebum Production: Zinc PCA inhibits excessive sebum production by reducing the activity of the 5-alpha reductase enzyme. This is critical, especially during hormonal acne periods. The key point is: Zinc PCA does not stop sebum production entirely; it balances it—maintaining the minimum oil the skin needs while preventing excess.

3. Antibacterial Effect: It inhibits the proliferation of *Propionibacterium acnes* (P. acnes), the bacteria that cause acne. It performs this effect selectively without harming the skin's beneficial microbiome—unlike broad-spectrum antibiotics, it does not lead to the formation of resistant bacteria.

4. Anti-inflammatory Mechanism: By suppressing the production of pro-inflammatory cytokines, it reduces redness, swelling, and sensitivity in existing pimples. It also regulates neutrophil activity to control excessive inflammatory responses.

5. The Humectant Effect of PCA: PCA (pyrrolidone carboxylic acid) is one of the skin's natural moisturizing factors (NMF). The PCA component in the Zinc PCA formula balances the drying potential of zinc, protecting the skin's moisture barrier. Result: Oil control + moisture balance in a single molecule.

7 Key Benefits of Zinc PCA Serum for the Skin

Smart Sebum Control: Balances excess oil production without drying out the skin. Provides a matte, balanced, and healthy-looking complexion all day long.

Acne and Pimple Prevention: Targets *P. acnes* bacteria to prevent the formation of new pimples. Reduces inflammation and redness of existing pimples.

Pore Tightening: Controls excess sebum to prevent clogged and enlarged pores. Reduces the appearance of pores significantly when combined with Niacinamide.

Skin Microbiome Balance: Selectively targets harmful bacteria while protecting beneficial microorganisms. Supports the skin's natural defense ecosystem.

Skin Barrier Strengthening: Supports ceramide production to strengthen the skin's protective layer. Reduces transepidermal water loss (TEWL).

Anti-inflammatory Soothing: Relieves inflammatory symptoms such as redness, swelling, and irritation. Can be safely used on sensitive and reactive skin.

Support for Skin Cell Renewal: Regulates keratinization processes to support the normal cell cycle. Reduces comedone formation by preventing hyperkeratinization (excessive skin thickening).

Zinc PCA + Niacinamide: Scientific Synergy

The combination of Zinc PCA and niacinamide (vitamin B3) is one of the best-documented synergies in skincare science. These two actives work through different mechanisms to complement each other:

What Niacinamide does: Strengthens the skin barrier (increases ceramide synthesis), supports collagen and hyaluronic acid production, reduces hyperpigmentation, shrinks the appearance of pores, and provides antioxidant protection.

What Zinc PCA does: Regulates sebum production at the source, targets acne bacteria, reduces inflammation, and balances the skin microbiome.

What happens together: While Niacinamide improves overall skin health and appearance, Zinc PCA takes on oil control and antibacterial defense. Niacinamide's pore-shrinking effect yields much stronger results when combined with Zinc PCA's sebum regulation. The NewLab's 10% Niacinamide + 1% Zinc PCA formula offers scientifically proven ratios of this synergy.

Who Should Use Zinc PCA Serum?

Oily skin: The skin type that shows the greatest effect from Zinc PCA. It is ideal for those struggling with all-day shine, enlarged pores, and a constant cycle of pimples.

Combination skin: Regulates the imbalance between excessive oiliness in the T-zone (forehead, nose, chin) and normal/dry texture in other areas. The PCA component provides moisture support without neglecting dry areas.

Acne-prone skin: Those experiencing active acne periods, hormonal pimples, blackheads, and whiteheads (comedones). Zinc PCA provides both prevention and soothing.

Sensitive but oily skin: Skin irritated by traditional acne products (benzoyl peroxide, high-concentration salicylic acid). Zinc PCA works without drying or irritating.

Young skin (adolescence): Excessive sebum production due to hormonal changes and initial acne periods. It can be safely used on young skin thanks to its gentle formulation.

How to Use Zinc PCA Serum?

Step 1 — Cleansing: Wash your face with a suitable cleanser to remove makeup, sebum, and dirt residues.

Step 2 — Toner (optional): If you use a toner, apply it before the serum and wait for it to absorb.

Step 3 — Zinc PCA Serum: Take a few drops of Niacinamide 10% + Zinc 1% Serum and distribute it over the entire face by gently massaging with your fingertips. Wait 1-2 minutes for it to absorb.

Step 4 — Moisturizer: Apply a moisturizer suitable for your skin type after the serum has been absorbed.

Step 5 — Sunscreen (morning): As the final step of your morning routine, apply SPF 30+ sunscreen.

Frequency: Can be used 2 times a day (morning and evening). Zinc PCA does not make the skin sensitive to the sun—it can be safely applied all four seasons, including summer.

Frequently Asked Questions

What is the difference between Zinc PCA and normal zinc (zinc oxide)?

The most fundamental difference is the mechanism of action. Zinc oxide remains on the surface of the skin, creating a physical barrier—which is why it is used as a UV filter in sunscreens. Zinc PCA, on the other hand, penetrates the skin to reach the sebaceous glands and control oil production at the source. Its absorption capacity is 30% higher than zinc oxide. For detailed information about different forms of zinc, you can check our Products containing Zinc page.

Is Zinc PCA serum suitable for dry skin?

Yes, unlike traditional zinc forms, Zinc PCA is not drying. The PCA component is one of the skin's natural moisturizing factors (NMF) and supports moisture retention capacity. When dry skin types use Zinc PCA serum with a moisturizer, they can obtain antioxidant protection, skin barrier support, and anti-inflammatory benefits.

How long does it take for Zinc PCA serum to show results?

In the first 3-5 days, a noticeable decrease in excessive oiliness on the skin is felt. Within 2-3 weeks, a reduction in new pimple formation and tightening of pores begins. The most comprehensive results—regular sebum balance, smooth skin texture, and controlled acne cycles—are usually achieved with 6-8 weeks of regular use.

Can Zinc PCA serum be used every day?

Yes. With its gentle structure, Zinc PCA can be safely used 2 times a day (morning and evening). It does not make the skin sensitive to the sun, does not exfoliate, and has a very low potential for irritation. These features distinguish it from actives with limited usage frequency, such as AHA or retinol.

Can Zinc PCA serum be used during adolescence?

Yes, Zinc PCA is a very suitable active for hormonal acne during adolescence. Its gentle formulation can be safely used on young skin. Unlike aggressive acne treatments (benzoyl peroxide, strong acids), it provides sebum control without drying or irritating the skin.

Can Zinc PCA serum and Vitamin C serum be used together?

It is not recommended to apply them at the same time as Vitamin C in pure ascorbic acid form—different pH requirements can reduce efficacy. However, they can be used without any issues in different time slots: Morning Vitamin C serum + sunscreen, evening Zinc PCA + niacinamide serum is an ideal routine.

Can Zinc PCA serum be applied to the eye area?

The Zinc PCA + niacinamide serum is formulated primarily for the face. For the eye area, the specially designed The NewLab Brightening Eye Serum (Caffeine 5% + Green Tea) should be preferred.

Can Zinc PCA serum be used during pregnancy?

Zinc PCA and niacinamide are considered generally safe ingredients for topical cosmetic use. However, as with all products containing active ingredients during pregnancy and breastfeeding, it is recommended to consult your doctor before use.
