Frequently asked questions

FAQ

Yes, this serum is safe for use during pregnancy and breastfeeding. It contains Sodium Ascorbyl Phosphate (SAP), a stable and gentle form of Vitamin C that is considered safe for pregnant and nursing mothers. The formula is free from retinoids, high-dose salicylic acid, hydroquinone, and other ingredients typically avoided during pregnancy.

Yes, this serum is fungal acne safe. It is free from ferments, problematic fatty acids (C12-C24), esters, polysorbates, and oils that feed Malassezia yeast. The formula relies on safe humectants like glycerin, sodium hyaluronate, and niacinamide that don't promote fungal growth.

Yes, SAP (Sodium Ascorbyl Phosphate) is a stable form of Vitamin C that can be used alongside most other actives. It works well with niacinamide (already in the formula), hyaluronic acid, and can be layered with retinol. For AHA/BHA, use them at different times of day to avoid irritation. Apply Vitamin C in the morning and retinol/acids at night for best results.

This serum is best suited for oily, combination, and acne-prone skin types due to its lightweight, non-greasy texture. It also works well for normal and dry skin when paired with a moisturizer. The gentle SAP formula makes it suitable for sensitive skin, though patch testing is recommended if you're highly reactive to fragrance.

You can expect to see initial hydration and smoother skin texture within the first week. Visible brightening typically appears within 2-4 weeks of consistent daily use. For more significant improvements in dark spots and skin tone, allow 4-8 weeks of regular application. Results vary based on individual skin conditions and concerns.

Apply this serum after cleansing and toning, before moisturizer. The order is: Cleanser → Toner → This Serum → Moisturizer → Sunscreen (AM only). For nighttime, you can follow with a richer cream or sleeping mask. The lightweight texture allows it to layer well under other products.

No, this serum has a low comedogenic rating of 1/5 and is considered non-comedogenic. It does not contain heavy oils, silicones, or pore-clogging ingredients. The lightweight gel texture is designed to absorb quickly without leaving residue that could block pores. It's suitable for acne-prone skin.

The serum has a PAO (Period After Opening) of 12 months. Once opened, use within one year for optimal efficacy. The stable SAP formula is less prone to oxidation than pure L-Ascorbic Acid, but store in a cool, dark place to maintain freshness. If the color changes to dark yellow/brown or develops an off smell, discontinue use.

— Skincarisma verdict
4.2 / 5 ★★★★☆

Verdict: Hanasui Vitamin C + Collagen Serum is an excellent entry-level brightening serum that punches above its weight class. At under $5 for a multi-active formula featuring Vitamin C, Niacinamide, Collagen, and Hyaluronic Acid, it offers remarkable value for skincare beginners or those on a budget. The gentle SAP form of Vitamin C makes it pregnancy-safe and suitable for sensitive skin, while the fungal acne-safe formula is a bonus for those prone to Malassezia issues. While the low Vitamin C concentration (1%) may not satisfy users seeking aggressive brightening, its gentle approach delivers gradual, sustainable results without irritation. Ideal for preventive skincare and maintaining healthy, radiant skin rather than treating severe hyperpigmentation.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
