Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate suitability for normal skin, as glycolic acid and salicylic acid provide effective exfoliation to address acne lesions, but the formula lacks sufficient emollient ingredients for optimal hydration.
  • While beneficial for general exfoliation, the product's primary ingredients are not specifically targeted to alleviate your redness and irritation.
  • The product is safe for your sensitive skin, containing no harsh or prohibited ingredients that would cause irritation.

How to apply

  • Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
  • Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
  • Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
  • Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
  • Always do a patch test before your first use and avoid getting the serum too close to your eyes .

People Say

★4.6Overall rating based on 1.9k+ reviews

This dual-action serum is widely praised by adults with oily and combination skin for simultaneously treating cystic acne and smoothing fine lines. While highly effective at reducing sebum and clearing congestion, users note it can be drying and may cause an initial "purge" period before results become visible. The summary is based on a very large amount of data and should definitely be taken into account.

Questions and answers

How well does SkinCeuticals Blemish + Age Defense work for sensitive skin?

SkinCeuticals Blemish + Age Defense is an average fit for sensitive skin because its strong acids exfoliate well, but the formula lacks enough moisturizing ingredients to keep skin soft. A treatment of this type needs soothing ingredients, antioxidants, and hydrating components to calm redness and irritation without causing dryness.

Journal of Cosmetic Dermatology, 2024BioMed Research International, 2020

Which ingredients make this serum a good fit for sensitive skin?

This serum is a fair fit for sensitive skin because it contains salicylic acid and glycolic acid to help clear breakouts, though it lacks soothing hydrators to calm redness. A treatment for sensitive skin needs soothing ingredients like niacinamide or snail secretion filtrate and extra moisture to keep the skin calm and comfortable.

BioMed Research International, 2020Journal of Cosmetic Dermatology, 2024

What does Salicylic Acid do for sensitive skin?

Salicylic acid may cause irritation on sensitive skin, so it requires careful use and good sun protection to keep skin comfortable. A product for this skin type needs gentle, soothing ingredients and a mild formula that respects the skin barrier.

The British Journal of Dermatology, 1999International Journal of Toxicology, 2003

What does Glycolic Acid do for sensitive skin?

Glycolic acid can be too harsh for sensitive skin, leaving it dry and irritated, so this type of skin needs a gentler exfoliating ingredient and calming plant extracts to keep the skin barrier safe and comfortable.

Cutaneous and Ocular Toxicology, 2022

Where does it go in a skincare routine for sensitive skin?

Apply this treatment in the evening, starting just once a week to see how your skin responds before using it more often. Because this product lacks sufficient hydrating and calming ingredients for your sensitive skin, a routine for this skin type needs extra soothing and moisturizing ingredients to keep it comfortable.

Can I use this serum with retinol, and in what order?

It is best to use this serum on alternating nights rather than mixing it with retinol, because combining strong exfoliating acids and retinol is likely to cause excessive dryness and irritation on sensitive skin. When you do use this treatment, apply it after cleansing and toning, and follow with a rich moisturizing cream to keep your skin soft and comfortable.

How often should I use it?

Start by using this treatment once a week in the evening to see how your skin tolerates the exfoliating acids. If your skin feels comfortable and you see good results, you may carefully use it more often. Sensitive skin needs products that provide soothing hydration alongside exfoliation to keep it calm and soft.

Can it clog pores, cause breakouts or purging for sensitive skin?

It is unlikely to clog pores, but initial breakouts or purging may happen with sensitive skin since it contains exfoliating acids. Reviewers note it can sometimes be drying or irritating. A treatment for sensitive skin needs soothing ingredients and extra moisture to keep skin calm.

Is this serum fragrance-free and alcohol-free?

It has no fragrance and contains drying alcohol (alcohol denat).
