Blemish + Age Defense FAQs

What does SkinCeuticals Blemish + Age Defense do?

SkinCeuticals Blemish + Age Defense is an oil-free corrective serum that targets both adult acne and early signs of ageing. It helps to reduce breakouts, refine pores, improve skin texture, and minimise fine lines using a combination of exfoliating acids and oil-regulating ingredients.

Who should use SkinCeuticals Blemish + Age Defense?

This serum is best suited to oily, combination, and acne-prone skin types, particularly those experiencing adult or hormonal breakouts alongside concerns such as enlarged pores, uneven texture, or early skin ageing.

How do you use SkinCeuticals Blemish + Age Defense?

Apply four to five drops to clean, dry skin once or twice daily, depending on tolerance. It can be used across the full face for overall correction or applied directly to areas prone to congestion. Always follow with a moisturiser and daily SPF, as the active ingredients can increase sensitivity to sunlight.

Can I use Blemish + Age Defense every day?

Yes, however it should be introduced gradually, especially if you are new to active acids. Starting with once daily or every other day allows the skin to build tolerance before increasing to more regular use.

Is SkinCeuticals Blemish + Age Defense good for acne?

Yes, it is specifically formulated for acne-prone adult skin. Ingredients such as salicylic acid and LHA help to clear pores, reduce active breakouts, and minimise the likelihood of future congestion.

Does Blemish + Age Defense help with ageing skin?

In addition to addressing breakouts, this serum also improves visible signs of ageing. Glycolic and citric acids support skin renewal, helping to smooth texture, refine fine lines, and restore a more radiant, even-looking complexion.

Can I use this serum with other active ingredients?

It can be used alongside other actives, but care should be taken to avoid over-exfoliation. Combining it with strong retinoids or additional exfoliating acids should only be done under professional guidance to maintain skin balance and barrier health.

Is SkinCeuticals Blemish + Age Defense suitable for sensitive skin?

Due to its high concentration of active ingredients, this formula may not be suitable for very sensitive or compromised skin. A patch test is recommended, and gradual introduction is key to assessing tolerance.

How long does it take to see results?

Many clients begin to notice clearer, smoother-looking skin within two to four weeks, with continued improvements in tone, texture, and overall clarity over time with consistent use.

Do I need SPF when using Blemish + Age Defense?

Yes, daily SPF is essential when using this product. The exfoliating acids increase the skin’s sensitivity to UV exposure, so consistent sun protection is necessary to maintain results and prevent further damage.
