SkinCeuticals Blemish + Age Defense

SkinCeuticals Blemish + Age Defense

A corrective serum for skin that refuses to choose between clarity and longevity.

Acne and visible signs of aging are not opposing concerns. They are often two sides of the same skin cycle. Blemish + Age Defense was designed precisely for this duality.

This oil-free, multi-acid serum targets congestion, breakouts, and uneven texture while simultaneously refining the appearance of fine lines, pores, and discoloration. The formulation is deliberate: strong enough to correct, balanced enough to respect aging skin.

For patients managing breakouts without sacrificing skin integrity, this is a holy grail product.

Why It’s Different

Blemish + Age Defense is built around a first-of-its-kind acid blend that combines alpha hydroxy acids, beta hydroxy acids, and dioic acid to address acne at the pore level while encouraging smoother, more even skin over time.

Rather than stripping the skin or over-drying blemishes, it works by:

• Normalizing cell turnover

• Keeping pores clear

• Improving surface texture and tone

The result is skin that looks clearer, calmer, and more refined — not irritated.

Who This Product Is Best For

• Adult acne or hormonal breakouts

• Congested or enlarged pores

• Uneven texture or tone

• Early signs of aging alongside blemishes

Not recommended during pregnancy or on compromised post-procedure skin unless directed by a provider.

When to use

• Evening use is preferred

• Can be used once daily, up to twice daily if well tolerated and provider-approved

Where it fits in your routine

• Apply after cleansing

• Use as your targeted treatment step

• Follow with hydration and moisturizer

On nights when Blemish + Age Defense is applied, it should be the only corrective active used.

How much to use

• 4–5 drops total

• Spread in a thin, even layer over acne-prone or congested areas

Important guidance
If sensitivity develops, reduce frequency rather than discontinuing completely. Consistency matters more than intensity.

Each ingredient in Blemish + Age Defense was chosen to serve both acne control and visible aging.

Glycolic Acid (3.5%)
An alpha hydroxy acid that gently exfoliates the skin’s surface, improving texture, radiance, and the appearance of fine lines while helping prevent pore congestion.

Dioic Acid (2%)
A multifunctional acid that helps regulate excess oil, reduce blemish formation, and support a more even skin tone. Particularly beneficial for adult acne and post-breakout discoloration.

Salicylic Acid (1.5%)
A beta hydroxy acid that penetrates into pores to dissolve congestion, reduce breakouts, and calm inflammation. Essential for acne-prone skin without compromising aging skin.

LHA (0.3%)
A derivative of salicylic acid that exfoliates more slowly and precisely, improving cell turnover and refining pores with less irritation than traditional exfoliants.

Citric Acid (0.5%)
An alpha hydroxy acid that supports gentle exfoliation and helps brighten uneven tone while contributing to overall skin smoothness.

HEPES (0.5%)
A buffering agent that enhances exfoliation efficiency while helping maintain skin comfort, improving tolerance to active acids over time.
