What Is By Nature Vitamin C and Collagen Serum?
The By Nature Vitamin C + Collagen Face Serum is a skincare product from By Nature Skincare, a brand based in New Zealand. The company focuses on natural and cruelty-free formulas. This serum comes in a generous 90ml (3 fl oz) bottle, which is larger than most serums on the market.
The formula combines Vitamin C with hydrolyzed marine collagen and turmeric root extract. These three ingredients work together to brighten skin tone, plump the skin, and give a fresh appearance. The serum has a lightweight gel texture that absorbs fast into the skin.
It is marketed as a product for all skin types. You can use it morning or evening before applying your moisturizer. Many users also love it as a pre-makeup primer because of its smooth, non-sticky finish.
The brand says this serum helps restore and energize tired skin. It aims to reduce dullness and improve the overall texture of your face and neck. The product is available on Amazon, Walmart, and the official By Nature Skincare website.
Who Should Use This Serum?
This serum works best for anyone who wants brighter and more hydrated skin. If your skin looks tired or dull after long days, this product can give it a visible boost. People with uneven skin tone have also found it helpful.
It suits dry, oily, combination, and normal skin types. The lightweight formula does not clog pores and does not leave a heavy feeling. If you have oily skin, you will appreciate how quickly it absorbs.
People in their late 20s to 50s will benefit the most from this serum. Vitamin C and collagen both address early signs of aging like fine lines and loss of firmness. If you are starting an anti-aging routine, this serum is a good entry point.
However, if you have very sensitive skin, proceed with caution. The formula contains fragrance (parfum), limonene, and linalool. These can cause irritation in some people. A patch test on your inner wrist or behind the ear is a smart first step.
Key Ingredients Breakdown
The star ingredients in this serum make it stand out from many budget-friendly options. Let’s look at what goes into the formula.
Ascorbic Acid (Vitamin C) is the pure form of Vitamin C. It is a proven antioxidant that helps fight free radical damage. It also supports collagen production and can brighten dark spots over time. This ingredient works best at a pH below 3.5 for maximum absorption.
Magnesium Ascorbyl Phosphate (MAP) is a stable form of Vitamin C. It is less irritating than pure Ascorbic Acid. MAP has proven skin-brightening abilities in human studies. It may also boost collagen production, though more research is needed.
Hydrolyzed Marine Collagen acts as a humectant. It helps the skin hold onto water and creates a smooth, plump surface. This is not the same as taking collagen supplements. Topical collagen mainly provides surface-level hydration and softness.
Turmeric Root Extract (Curcuma Longa) offers anti-inflammatory and antioxidant benefits. It helps energize dull skin and can regulate sebum production. Turmeric gives this serum its brightening and revitalizing character.
Glycerin is a trusted humectant that draws water to the skin. It supports the skin barrier and works well for all skin types. Chamomile Flower Extract adds soothing and calming properties to round out the formula.

How to Apply By Nature Vitamin C and Collagen Serum
Using this serum correctly will help you get the best results. Follow these simple steps for your daily routine.
Step 1: Cleanse your face. Start with a gentle cleanser to remove dirt, oil, and makeup. Pat your skin dry with a clean towel. Never apply serum on dirty skin because it reduces absorption.
Step 2: Apply the serum. Pump one to two drops onto your fingertips. Gently pat the serum onto your face and neck. Focus on areas where you see dullness, uneven tone, or fine lines. Do not rub it harshly.
Step 3: Wait for absorption. Give the serum about 30 to 60 seconds to absorb fully. You will notice the skin feels smooth and slightly dewy. This makes it an excellent pre-makeup base.
Step 4: Moisturize. Follow up with a lightweight moisturizer to lock in all the benefits. If you use the serum in the morning, always finish with sunscreen. Vitamin C can make your skin more sensitive to UV rays.
You can use this serum once or twice daily. Morning use pairs well with sunscreen for added UV protection. Evening use allows the ingredients to work while your skin repairs overnight.
What Does It Smell Like and Feel Like?
The texture of this serum is light, silky, and gel-like. It does not feel heavy or sticky on the skin. Many users describe it as almost water-like in consistency. It spreads easily and absorbs within seconds.
The scent has a mild, fresh fragrance. Some users describe it as slightly citrusy with a hint of floral notes. The fragrance comes from added parfum along with natural components like limonene and linalool.
If you prefer fragrance-free products, this serum may not be ideal. The scent is subtle but present. Most users find it pleasant. However, a few reviewers with sensitive noses noted the smell was stronger than expected.
On the skin, it leaves a smooth, slightly dewy finish. There is no greasy residue. Your skin feels hydrated and soft immediately after application. This is one reason many users enjoy it as a primer before makeup.
Real User Reviews and Feedback
User feedback for the By Nature Vitamin C + Collagen Serum has been mostly positive across Amazon, Walmart, and social media platforms like TikTok and Instagram.
Positive reviews highlight several common themes. Users say the serum makes their skin look brighter and more refreshed within days. Many praise the lightweight texture and fast absorption. Several reviewers have called it “better than expensive brands” and say they noticed improvements in skin tone, texture, and moisture.
Some users on Walmart gave it 5-star ratings and mentioned it feels amazing on the skin. One reviewer said it was the “best vitamin C serum I have ever used.” Others love the large 3 fl oz bottle size, which offers great value for money.
Negative feedback is less common but worth noting. A few users mentioned the serum develops a funky smell over time if not stored in a cool place. The brand recommends keeping it in the fridge, which helps preserve the Vitamin C. Some users with very sensitive skin experienced mild irritation, likely from the fragrance ingredients.
Overall, the serum holds a strong rating across multiple retail platforms. It performs well for the price and delivers visible results for most users.
Pros and Cons of By Nature Vitamin C and Collagen Serum
Pros:
- Affordable price at around $14 to $18 for a 90ml bottle
- Two forms of Vitamin C for both brightening and antioxidant protection
- Contains hydrolyzed marine collagen for surface-level plumping and hydration
- Turmeric extract adds energizing and anti-inflammatory benefits
- Large bottle size compared to competitors
- Paraben-free, alcohol-free, and cruelty-free formula
- Works great as a pre-makeup primer
Cons:
- Contains fragrance (parfum) which may irritate sensitive skin
- Must be stored properly or it can develop an unpleasant smell
- Vitamin C concentration is not disclosed, making it hard to compare with clinical-grade serums
- Collagen works mainly on the surface and does not penetrate deeply into the skin
How Does It Compare to High-End Vitamin C Serums?
Many premium Vitamin C serums cost between $50 and $180. The SkinCeuticals C E Ferulic, for example, is priced around $182 and is often called the gold standard. So how does this $15 serum compare?
The By Nature serum uses Ascorbic Acid and Magnesium Ascorbyl Phosphate. This is a solid combination. However, high-end serums often include stabilizing agents like ferulic acid and Vitamin E. These ingredients extend the shelf life of Vitamin C and boost its antioxidant power.
The concentration of Vitamin C in By Nature’s formula is not listed on the packaging. Premium serums usually contain 10% to 20% Vitamin C with clinical studies to back up their claims. This is one area where the By Nature serum falls short.
That said, the By Nature serum holds its own for everyday brightening and hydration. If you are on a budget and want visible results without spending a fortune, this serum delivers solid performance. It is not a replacement for clinical-grade products, but it offers real benefits at a fraction of the cost.
Does Vitamin C and Collagen Work Well Together?
Yes, Vitamin C and collagen make a smart pairing in skincare. They address different skin concerns and complement each other well.
Vitamin C is an antioxidant that protects skin cells from damage. It also stimulates your body’s own collagen production. This means it works from the inside to strengthen the skin’s structure over time.
Topical collagen, on the other hand, provides immediate surface benefits. Hydrolyzed collagen acts as a humectant that locks moisture into the upper layers of the skin. It creates a plump, smooth appearance right after application.
Together, they offer both short-term hydration and long-term skin support. Vitamin C boosts natural collagen production while the topical collagen provides instant moisture. This dual action makes the combination popular in modern skincare formulas.
The addition of turmeric extract in this serum adds a third layer of benefit. Turmeric is anti-inflammatory and antioxidant. It helps calm irritated skin while also brightening the complexion. All three ingredients work in harmony.
Is This Serum Worth the Price?
At around $14 to $18 for a 90ml bottle, the By Nature Vitamin C + Collagen Serum is one of the best value options in its category. Most competitor serums come in 30ml (1 oz) bottles at similar or higher prices.

You get three times the product for the same cost as many other serums. If you use one to two pumps daily, a single bottle can last six to eight weeks. That makes the daily cost extremely low.
The formula delivers real results for brightening, hydration, and skin texture improvement. It may not match the potency of a $180 clinical serum, but for everyday skincare, it performs above its price point.
If you are new to Vitamin C serums or on a tight budget, this is a smart buy. You get clean ingredients, a generous size, and noticeable results. The risk is low, and the reward is high for most users.
Tips for Getting the Best Results
To maximize the benefits of this serum, follow a few simple tips.
Store it in the fridge. Vitamin C oxidizes when exposed to air, light, and heat. Keeping the serum cool extends its shelf life and preserves its potency. A fridge-cold serum also feels refreshing on the skin.
Use sunscreen every morning. Vitamin C boosts the skin’s UV protection, but it is not a sunscreen substitute. Always apply SPF 30 or higher after your serum and moisturizer. This protects your skin and prevents dark spots from returning.
Be consistent. Results build over time. Use the serum daily for at least two to four weeks before judging its performance. Most users see visible changes in skin brightness and texture within this period.
Pair it with the right moisturizer. A lightweight, hydrating moisturizer locks in the serum’s benefits. Look for one with hyaluronic acid or ceramides for extra moisture support.
Do a patch test first. If you have sensitive skin, test the serum on a small area for 24 hours. This helps you avoid any potential allergic reaction to the fragrance ingredients.
Where to Buy By Nature Vitamin C and Collagen Serum
You can purchase this serum from several trusted retailers. Amazon is the most popular option, where it is listed under ASIN B08FGJRSCM. Prime members often enjoy free shipping and fast delivery.
Walmart also carries this serum both online and in select stores. The price at Walmart is typically around $14.97. This is a convenient option if you prefer to shop in person.
The official By Nature Skincare website (bynatureskincare.com) sells the serum directly. Shopping from the official site ensures you get the freshest product. You can also explore their full Vitamin C + Collagen skincare range there.
Check for coupons and deals on Amazon. The listing sometimes features clip-on coupons or subscribe-and-save discounts. These can bring the price down even further.
Final Verdict on By Nature Vitamin C and Collagen Serum
The By Nature Vitamin C + Collagen Face Serum is a solid budget-friendly option for anyone looking to brighten and hydrate their skin. It combines two forms of Vitamin C with marine collagen and turmeric extract in a clean formula.
The serum absorbs fast, feels lightweight, and works well under makeup. Most users see visible improvements in skin tone and texture within two weeks. The large 90ml bottle offers excellent value compared to competitor products.
The main downside is the inclusion of fragrance, which may not suit very sensitive skin types. The undisclosed Vitamin C concentration is also a minor concern for advanced skincare users.
Overall, we give this serum a strong recommendation for beginners, budget shoppers, and anyone who wants a reliable daily brightening serum. It does what it promises at a price that is hard to beat.
