Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening for your combination skin due to ascorbic acid, which helps to even skin tone and provides antioxidant activity. Allantoin and tocopherol offer general skincare benefits like hydration and soothing, which are supportive for your oily shine but not targeted for this specific concern.
- The formula is highly suitable for combination skin, with ascorbic acid and tocopherol offering good antioxidant activity and collagen stimulation.
- The safety profile is excellent, with no risks of irritation for your combination skin due to the absence of prohibited or harsh ingredients.
How to apply
- Use your serum as part of your PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
- Apply the serum after cleansing and toner, and right before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏳for it to soak in.
- Apply the serum on clean and dry skin since your skin is not sensitive.
- Always do a patch test before using the serum for the first time, and avoid the eye area .

Questions and answers
How well does Dr. Althea Pure Vitamin C 50% Boosting Powder work for combination skin?
Dr. Althea Pure Vitamin C 50% Boosting Powder works moderately well for combination skin because it offers decent brightening and antioxidant support. While it is safe and unlikely to cause irritation, other products fit this skin better by containing ingredients like niacinamide, propolis, and zinc PCA that specifically regulate oiliness and provide optimal hydration without imbalance.
Which ingredients make this powder a good fit for combination skin?
Ascorbic acid makes this powder a good fit for combination skin by offering moderate brightening to even your skin tone, while tocopherol and allantoin provide general soothing and hydration. Treatments that fit this skin best need ingredients like niacinamide, zinc PCA, and propolis to regulate oiliness and enhance radiance without causing irritation.
What does Vitamin C do for combination skin?
Vitamin C helps brighten dull areas and smooth out uneven texture on combination skin while protecting against daily environmental stress. It may also help keep pores clear and skin firm by supporting collagen production, though drier spots may need an added moisturizer to stay comfortable.
What does Silica do for combination skin?
Silica helps absorb excess oil in shiny areas while keeping dry patches feeling balanced and smooth. This type of ingredient is often used in lightweight formulas to give combination skin a clean, matte finish without feeling heavy.
Where does this powder go in a skincare routine for combination skin?
This treatment goes in the evening routine after cleansing and before moisturizing, though it can also be used weekly depending on your skin. Combination skin needs an antioxidant treatment that balances brightening with targeted hydration and oil control.
Can I use this powder with retinol, and in what order?
You can use this treatment alongside retinol, but it is best to apply them on alternate nights or separate them into morning and evening routines to avoid potential irritation. Because combination skin needs targeted balancing alongside brightening, products of this type work best when they also include ingredients that control oily shine and deeply hydrate dry areas.
How often should I use this powder?
You can use this treatment in your evening routine once a week to start, and then carefully use it more often if your skin tolerates it well and shows good results. Because combination skin does best with products that balance oily shine while gently brightening and soothing, this skin type also needs targeted oil control and lightweight hydration.
Can this powder clog pores, cause breakouts or purging for combination skin?
This powder is unlikely to clog pores or cause breakouts for combination skin because it has an excellent safety profile with no harsh or prohibited ingredients. However, combination skin needs a product with targeted oil-balancing ingredients to better manage excess shine and prevent clogged pores.
Is this powder fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
