03

Ingredient breakdown

INGREDIENTS

Salicylic Acid (BHA) ~0.5-2%Proven

Oil-soluble beta hydroxy acid that penetrates deep into pores to dissolve sebum, unclog blackheads, and reduce inflammation. The gold standard for acne treatment.

  • Mechanism: Penetrates oil-filled pores to break down dead skin cells and excess sebum
  • Clinical Evidence: FDA-approved OTC acne treatment at 0.5-2% concentration
  • Anti-inflammatory: Has aspirin-like structure that calms redness and irritation

Lactic Acid (AHA)Proven

Gentle alpha hydroxy acid that exfoliates the skin surface while providing hydration. Helps improve skin texture and fade post-acne marks.

  • Dual Action: Exfoliates dead skin cells while attracting moisture to skin
  • Gentler than Glycolic: Larger molecule size means less irritation for sensitive skin
  • Brightening: Helps fade hyperpigmentation and post-inflammatory marks

Gluconolactone (PHA)Proven

Next-generation polyhydroxy acid that provides gentle exfoliation with added antioxidant benefits. Ideal for sensitive skin that cannot tolerate traditional AHAs.

  • Gentle Formula: Larger molecule size provides slower, less irritating exfoliation
  • Antioxidant: Provides protection against free radical damage comparable to Vitamin E
  • No Photosensitivity: Studies show PHAs do not increase sun sensitivity like AHAs

Carnitine 2XPromising

Amino acid derivative that helps regulate sebum production by supporting healthy skin metabolism and lipid breakdown.

  • Oil Control: Studies show topical L-carnitine can reduce excess oil and improve skin oil balance
  • Cell Energy: Supports healthy skin metabolism by boosting lipid breakdown
  • Anti-aging: Research shows it improves skin resilience against UV damage and aging

Licochalcone A (LICO A)Proven

Eucerin's signature ingredient extracted from licorice root. Powerful anti-inflammatory that soothes irritated acne-prone skin.

  • Anti-inflammatory: Reduces redness and inflammation associated with acne
  • Antioxidant: Protects skin from oxidative stress
  • Soothing: Calms reactive, sensitive skin without irritation

Panthenol (Pro-Vitamin B5)Proven

Humectant that deeply hydrates while supporting skin barrier repair. Prevents the dryness often associated with acne treatments.

  • Hydration: Attracts and holds moisture in the skin as a humectant
  • Barrier Support: Promotes production of lipids essential for healthy skin barrier
  • Wound Healing: Supports fibroblast proliferation for faster healing of acne lesions
Prevents the drying and peeling commonly experienced with acid-based acne treatments.

Frequently asked questions

FAQ

This serum contains Salicylic Acid (BHA), which requires caution during pregnancy and breastfeeding. While ACOG considers topical salicylic acid under 2% generally safe, we recommend consulting your healthcare provider before use. If you're breastfeeding, avoid applying near the breast area and wash hands thoroughly after application.

No, this serum is NOT fungal acne safe. It contains Cetearyl Alcohol, Stearic Acid, and Pentaerythrityl Tetraisostearate, which can potentially feed malassezia yeast. If you have fungal acne/pityrosporum folliculitis, consider the Eucerin DermoPure Triple Effect Serum instead, which is fungal acne safe.

Use caution when combining with other actives. This serum already contains AHA, BHA, and PHA, so layering additional acids may cause irritation. Avoid using with retinol in the same routine - alternate days instead. Vitamin C can be used in the morning while using this serum at night. Always introduce new combinations gradually.

This serum is best for oily, combination, and acne-prone skin types. It excels at controlling sebum production and treating comedonal acne (blackheads and whiteheads). It's also suitable for sensitive acne-prone skin due to its soothing ingredients. Dry skin types may find it slightly drying and should pair with a richer moisturizer.

You may notice reduced redness and soothing effects immediately. Sebum control typically improves within 1-2 weeks. Visible reduction in acne and comedones usually occurs around weeks 2-4. For full prevention benefits and optimal results, consistent use for 6-8 weeks is recommended. Some users may experience initial purging in the first 1-2 weeks.

Apply after cleansing and toning (if using a toner), before moisturizer. In the morning: Cleanser → Toner → SOS Serum → Moisturizer → Sunscreen SPF 30+. At night: Cleanser → Toner → SOS Serum → Moisturizer. Always allow 30 seconds for absorption between steps.

No, this serum is clinically tested to be non-comedogenic and non-acnegenic, meaning it will not clog pores or cause acne. It has a very low comedogenic rating of 1/5. The BHA (salicylic acid) actually helps unclog existing pores by dissolving sebum and dead skin cells.

The serum has a Period After Opening (PAO) of 12 months. The 40ml bottle, when used twice daily as recommended, typically lasts 4-6 weeks. Store in a cool, dry place below 25°C and away from direct sunlight to maintain efficacy throughout its shelf life.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: Eucerin Pro Acne Solution SOS Serum is an excellent clinically-proven option for those with oily and acne-prone skin seeking a comprehensive treatment. The triple acid complex (AHA+BHA+PHA) combined with sebum-controlling Carnitine and soothing Licochalcone A delivers impressive results backed by clinical studies. The fragrance-free, non-comedogenic formula from a trusted German pharmacy brand makes it a reliable choice. However, it's not suitable for fungal acne sufferers, and pregnant/breastfeeding individuals should consult a doctor first. At its price point, it offers good value with pharmacy-grade quality and proven efficacy.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.

We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.

A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
