How to apply

Apply to freshly cleansed skin in the morning before your moisturizer and always follow with SPF. Use a few drops sparingly—Vitamin C is potent. If your skin is sensitive, start with every other day or mix a drop into your cream. Product may darken over time—this is normal and does not reduce effectiveness.
FAQs

Is this serum safe for mature skin (50+) with sensitivity?
Yes. It’s formulated to be gentle despite its potency. If you are sensitive to strong formulas, begin with every other day and patch test first.

How often should I use C+ Serum Forte 25%?
Ideal usage is every morning. However, if new to strong Vitamin C, start with every other morning until your skin adjusts.

Will it sting or irritate?
Some tingling is normal, especially with potent Vitamin C. If irritation lasts more than 20-30 minutes, rinse and reduce usage.

Does the color change over time?
Yes, the serum may gradually darken due to oxidation—this is normal and does not affect performance.

Can I use it under makeup and sunscreen?
Absolutely. Apply in the morning, let it absorb, then layer with your moisturizer and always finish with SPF.

    I alternate this with the C-vitamin booster. Absorbs quickly, not oily, makes skin soft and glowing.

    Very satisfied

    This serum works well in every way. Easy to apply and spread, very economical, feels great on the skin and absorbs well so it layers nicely under day cream. My skin seems to really like it.
