Collection: Zinc-Containing Skin Care Products

What is Zinc and Why is It Used in Skincare?

Zinc is an essential mineral involved in over 300 enzymatic reactions in the body and is critical for skin health. In skincare, zinc has scientifically proven effects in regulating sebum production, fighting acne-causing bacteria, and reducing inflammation. Zinc PCA (a combination of zinc and pyrrolidone carboxylic acid) stands out as the most effective form of zinc in modern skincare formulations, boasting up to 30% higher absorption capacity compared to zinc oxide or zinc sulfate.

Zinc-containing skincare products are the strongest allies for oily and acne-prone skin. While the sebum-regulating effect of zinc prevents pores from clogging, its antibacterial and anti-inflammatory properties fight active breakouts. However, the benefits of zinc are not limited to oily skin: it contributes to every skin type through its antioxidant effects, capacity to strengthen the skin barrier, and support for cell regeneration.

The NewLab Zinc-Containing Skincare Products

The NewLab offers a potent anti-acne formulation by combining the sebum-regulating power of zinc with high-concentration niacinamide.

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

One of The NewLab's most preferred serums, this formula strengthens the skin barrier, reduces the appearance of pores, and evens out skin tone with 10% Niacinamide, while 1% Zinc PCA regulates sebum production and fights acne-causing bacteria. Its Panthenol (Vitamin B5) content moisturizes and soothes the skin, while Allantoin supports skin repair. With its water-based, lightweight texture, it is suitable for all skin types; because it does not make the skin sensitive to the sun, it can be safely used in any season, including summer.

Zinc PCA vs. Zinc Oxide vs. Zinc Sulfate: Which Zinc Form is More Effective?

Three different forms of zinc are used in skincare products, each with different strengths:

Zinc PCA (Zinc Pyrrolidone Carboxylate): The most effective form in skincare serums. It is considered the gold standard in sebum regulation. It combines the antibacterial and anti-inflammatory effects of zinc with the moisture-retaining capacity of PCA. Research shows it provides up to 30% more absorption compared to zinc oxide or zinc sulfate. As it interacts with skin proteins, it creates a "reservoir effect," ensuring the continuous release of active zinc. The NewLab's Niacinamide + Zinc Serum uses this form. → Discover products containing Zinc PCA

Zinc Oxide: Used as a physical UV filter in sunscreens. It provides broad-spectrum UVA/UVB protection. It also exhibits soothing and mildly antibacterial effects. The NewLab's SPF 50+ Sunscreen formula contains zinc oxide.

Zinc Sulfate: An older and simpler form. Generally used in dermatological lotions and creams. Its absorption is lower compared to other forms, and it can have a drying effect on some skin types.

Benefits of Zinc-Containing Serum for the Skin

Sebum Regulation and Oil Control: Zinc PCA controls the activity of sebaceous glands to reduce excessive sebum production. It provides a matte and balanced appearance. It combats the problem of shine throughout the day in oily and combination skin.

Anti-Acne and Anti-Blemish Effect: Zinc's antibacterial properties inhibit the proliferation of *P. acnes* bacteria, which cause acne. Its anti-inflammatory effect reduces the redness and swelling of existing pimples. Regular use significantly reduces the formation of new breakouts.

Pore Tightening: By balancing sebum production, it prevents pores from clogging and enlarging. When used with niacinamide, the effect of reducing the appearance of pores is strengthened.

Strengthening the Skin Barrier: Zinc supports the production of ceramides and other intercellular lipids, strengthening the skin's protective barrier. It reduces transepidermal water loss (TEWL), ensuring the skin stays hydrated.

Anti-inflammatory and Soothing Effect: By inhibiting pro-inflammatory cytokines, it reduces redness, swelling, and irritation on the skin. It shows a soothing effect on sensitive and reactive skin.

Antioxidant Protection: By neutralizing free radicals, it prevents cell damage caused by environmental stressors. It delays the formation of early signs of aging.

Skin Cell Regeneration Support: Zinc contributes to the repair of skin tissue and cell renewal. It accelerates the healing process of acne scars and minor skin damage.

Zinc + Niacinamide: Why Are They Used Together?

The combination of zinc and niacinamide (Vitamin B3) is considered the most powerful synergistic duo in skincare—and many brands, from The Ordinary to The NewLab, offer this duo in a single formulation. There is a scientific reason for this:

Niacinamide strengthens the skin barrier, supports collagen production, reduces the appearance of pores, and lightens hyperpigmentation. However, it is limited in directly regulating sebum production.

Zinc PCA comes into play right here: it reaches the sebaceous glands to control excessive oil production at the source and adds an antibacterial effect.

When the two actives work together: Niacinamide improves overall skin health and appearance, while zinc takes care of sebum and bacterial control. The result is a more balanced, clearer, and smoother skin. The NewLab's 10% Niacinamide + 1% Zinc PCA formula offers one of the most effective ratios of this synergy.

Zinc vs. Salicylic Acid (BHA): Which One for Acne Care?

Both actives are cornerstones of acne care, but they work through different mechanisms:

Zinc (Zinc PCA): Regulates sebum production at the source, exhibits antibacterial effects, and reduces inflammation. It is well-tolerated even by sensitive skin and has no drying effect. Suitable for daily morning and evening use.

Salicylic Acid (BHA): With its oil-soluble structure, it penetrates into pores, physically clears blockages, and exfoliates dead cells. It provides a more potent cleansing effect but may cause dryness and sensitivity in some skin types.

They complement each other: While zinc targets the source of clogging by preventing sebum production, BHA clears existing blockages. A routine of zinc + niacinamide serum in the morning and BHA toner/serum in the evening creates a comprehensive strategy for acne care.

Zinc vs. Vitamin C: Can They Be Used Together?

These two actives perform different tasks, and there are points to consider when using them together:

Zinc (Zinc PCA): Works with a focus on acne and oiliness through sebum control, antibacterial effects, and anti-inflammatory properties.

Vitamin C (ascorbic acid): Provides antioxidant protection, brightening, and support for collagen synthesis.

Applying Vitamin C in the form of pure ascorbic acid and niacinamide + zinc serum at the same time is not recommended—the pH difference can reduce effectiveness. However, they can be used safely in different time slots: Vitamin C serum in the morning and zinc + niacinamide serum in the evening is an ideal routine.

How to Use Zinc-Containing Serum?

Cleansing: Wash your face with a gentle cleanser. Purify the oil and dirt on the skin surface with The NewLab Cleansers.

Toner (optional): If you use a toner, apply it before the serum and wait for it to be absorbed.

Serum application: Apply a few drops of Niacinamide 10% + Zinc 1% Serum to clean skin and spread it with gentle massages using your fingertips. Wait for it to be absorbed (about 1-2 minutes).

Moisturizer: After the serum is absorbed, apply a moisturizer suitable for your skin type.

Sunscreen (morning): Apply SPF 30+ sunscreen as the final step in your morning routine.

Frequency of use: Can be used twice a day, morning and evening. It does not make the skin sensitive to the sun, so it can be safely applied during the summer months.

Best Combinations: Which Actives Can Zinc Be Used With?

Zinc + Niacinamide: The golden duo. Sebum control + barrier strengthening + pore tightening. This combination is available pre-formulated in The NewLab serum.

Zinc + Hyaluronic Acid: Oil control + deep hydration. Meets the hydration needs of oily skin while maintaining sebum balance.

Zinc + BHA (Salicylic Acid): Comprehensive acne strategy. Zinc assumes the role of prevention, BHA the role of cleansing. Zinc in the morning and BHA in the evening is recommended.

Zinc + Alpha Arbutin: For post-acne marks and blemishes. While zinc prevents new acne formation, alpha arbutin lightens existing blemishes.

Zinc + Retinol: Anti-aging + acne care. A powerful anti-aging + sebum control routine is created by using zinc in the morning and retinol in the evening.

Points to Consider

Do not use simultaneously with Vitamin C: Avoid applying niacinamide + zinc serums at the same time as Vitamin C serums in pure ascorbic acid form. Using them at different times (morning/evening) is the safest approach.

Purging may occur at the start: In the first 1-2 weeks, some users may notice a temporary increase in breakouts as existing micro-comedones come to the surface. This is a normal purging process and usually subsides within 2-3 weeks.

A sticky feeling is normal: Niacinamide + zinc serums may leave a slightly sticky feeling after application. This usually disappears within 10-15 minutes and goes away completely when moisturizer is applied.

Concentration is important: For Zinc PCA, a concentration of 0.5-1% is the effective and safe range. The NewLab serum contains 1% Zinc PCA—this is the optimal dosage proven effective in scientific studies.

Storage: Store in a cool, dry place away from sunlight. Consume within 12 months after opening.

Frequently Asked Questions

What is Zinc PCA and how does it differ from regular zinc?

Zinc PCA is an advanced form of zinc formed by the combination of zinc and pyrrolidone carboxylic acid (PCA). It provides up to 30% higher absorption compared to regular zinc (zinc oxide, zinc sulfate). The PCA component is one of the skin's natural moisturizing factors, which balances the drying effect of zinc and allows it to reach the sebaceous glands more effectively.

Can non-oily skin types use zinc serum?

Yes. The benefits of Zinc PCA are not limited to oil control. Its antibacterial, anti-inflammatory, and antioxidant effects are valuable for all skin types. Dry skin types can use zinc serum together with a moisturizer to obtain both skin barrier support and antioxidant protection.

How many times a day should niacinamide + zinc serum be used?

It can be used twice a day (morning and evening). The serum does not make the skin sensitive to the sun, so there is no additional concern for morning use. However, do not forget to apply sunscreen as the final step in your morning routine.

Does zinc serum dry out pimples?

Zinc PCA works without drying the skin, unlike traditional forms of zinc. It balances sebum production at the source but preserves the skin's moisture. The PCA component it contains also has moisture-retaining capacity. Therefore, it soothes pimples and reduces their inflammation, but does not show a drying-peeling effect.

Is zinc serum effective for blackheads?

Yes, zinc serum is effective in preventing the formation of blackheads. By regulating sebum production, it prevents pores from getting clogged with excess oil. However, for physically clearing existing blackheads, using it together with BHA (salicylic acid) yields more comprehensive results.

Does zinc serum shrink pores?

Zinc PCA eliminates the main reason for pore enlargement by balancing sebum production. When working with niacinamide, the effect of reducing the appearance of pores is strengthened. Clinical studies have shown that the niacinamide + zinc combination provides a significant reduction in the appearance of pores within 4 weeks.

Can zinc serum be used with Vitamin C?

Simultaneous application with Vitamin C in pure ascorbic acid form is not recommended. However, it can be used safely in different time slots: Vitamin C serum + sunscreen in the morning, zinc + niacinamide serum in the evening is an ideal order. The risk of interaction is lower with stabilized forms of Vitamin C.

Can zinc serum be used during pregnancy?

Zinc PCA and niacinamide are generally considered safe components for topical use. However, as with all products containing active ingredients, consulting your doctor during pregnancy and breastfeeding is the most appropriate approach.

My acne increased during the first use; is this normal?

Yes, this is a normal process known as "purging." Niacinamide and zinc can accelerate the skin cell cycle, causing micro-comedones under the skin to surface. This usually subsides within 2-3 weeks, followed by clearer skin. However, in cases of worsening that lasts longer than 4 weeks and intensifies, discontinue use and consult a specialist.

Is zinc serum effective for acne scars?

Zinc can accelerate the healing process of acne scars with its cell renewal support. However, for significant acne scars and hyperpigmentation, being supported with targeted actives such as alpha arbutin, Vitamin C, or AHA yields more effective results.

Balance Your Skin with the Power of Zinc

Zinc is a powerful active that makes a difference, especially for oily, acne-prone, and large-pored skin. The NewLab's Niacinamide 10% + Zinc 1% Serum offers sebum control, pore tightening, and skin barrier support in a single product by combining these two powerful actives in scientifically proven ratios.
