Frequently asked questions
FAQUse with caution. Alpha-Arbutin is a derivative of hydroquinone and breaks down into this compound on the skin. While arbutin has lower toxicity than pure hydroquinone and some studies suggest it may be safe, there is limited research on its use during pregnancy and breastfeeding. Most dermatologists recommend avoiding arbutin during pregnancy and nursing as a precaution. Always consult your healthcare provider before using any brightening products during this time. Safer alternatives include Vitamin C or Azelaic Acid.
Yes! This serum is considered fungal acne safe. The formula does not contain ingredients that feed malassezia yeast, such as fermented ingredients, fatty acids (C11-C24), oils, polysorbates, or esters. It is oil-free and uses a water-based formula with safe humectants like glycerin, sodium hyaluronate, and propylene glycol. Safe for those prone to fungal acne/pityrosporum folliculitis.
Alpha-Arbutin is generally well-tolerated and plays nicely with most other actives. You can safely combine it with: Vitamin C (great combination for enhanced brightening), Niacinamide, Hyaluronic Acid, and Peptides. For AHAs/BHAs and Retinol, you can use them together, but introduce gradually to avoid irritation. Consider using arbutin in the morning and retinol at night, or alternating days when starting out. Always listen to your skin and scale back if you experience irritation.
This serum works well for all skin types but is particularly excellent for oily, combination, and acne-prone skin due to its lightweight, oil-free, water-based formula that absorbs quickly without leaving residue. The 4D Hyaluronic Acid provides good hydration for normal to dry skin, though those with very dry skin may want to layer with a richer moisturizer. Its fragrance-free formula also makes it suitable for sensitive skin types (patch test recommended).
Results timeline varies by individual and severity of hyperpigmentation. Generally: Week 1-2: Improved hydration and skin texture. Week 4-6: Subtle brightening, newer spots may start fading. Week 8-12: More visible reduction in dark spots and hyperpigmentation. Month 3+: Significant improvement in stubborn pigmentation. Consistency is key - use twice daily with diligent sunscreen application. Deeper, older pigmentation takes longer to treat than recent spots.
Apply this serum after cleansing and toning, but before heavier products. The order is: 1) Cleanser, 2) Toner (optional), 3) This Arbutin Serum, 4) Other serums/treatments if using, 5) Moisturizer, 6) Sunscreen (AM only). Apply to slightly damp skin for better absorption. Wait 15-30 seconds between products. Can be used both morning and evening, but sunscreen is mandatory during daytime use.
No, this serum has a low comedogenic rating of 1/5. It is oil-free, silicone-free, and contains no known pore-clogging ingredients. The water-based formula with lightweight humectants like glycerin and hyaluronic acid is non-comedogenic and suitable for acne-prone and congested skin. It is also fungal acne safe, making it a great choice for those prone to breakouts or clogged pores.
The serum has a Period After Opening (PAO) of 12 months. Once opened, use within one year for optimal efficacy. The 30ml bottle typically lasts 4-8 weeks with twice-daily use (3-4 drops per application). Store in a cool, dry place away from direct sunlight to maintain stability. The Alpha-Arbutin is stable in this formulation, but exposure to heat and light can degrade actives over time.
Verdict: The Purest Solutions Brightening Serum offers excellent value as an entry-level brightening treatment. With its 2% Alpha-Arbutin and impressive 4D Hyaluronic Acid complex, it delivers gentle yet effective results for hyperpigmentation at an unbeatable price point. The fungal acne-safe, fragrance-free formula makes it accessible to a wide range of skin types. While it requires patience and consistent sunscreen use, those seeking an affordable, clean-beauty approach to fading dark spots will find this Turkish skincare gem a worthy addition to their routine. Best for those with oily, combination, or acne-prone skin who want gradual, gentle brightening without harsh ingredients.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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.
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
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
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.
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.
