β Frequently Asked Questions
Blemish + Age Defense contains 1.5% salicylic acid, which is below the 2% threshold generally considered safe during pregnancy. However, it also contains glycolic acid and high alcohol content. While topical absorption is minimal, we recommend consulting your healthcare provider before use during pregnancy. For breastfeeding, avoid applying to areas that may contact baby's skin.
Yes! This serum is fungal acne safe. It contains no fatty acids, oils, or esters that feed malassezia yeast. The glycolic acid and salicylic acid actually help combat fungal overgrowth by exfoliating the skin surface. The minimal, oil-free formula makes it an excellent choice for those prone to fungal acne.
With Vitamin C: Yes, apply vitamin C first, wait 1-2 minutes, then apply Blemish + Age Defense. This is SkinCeuticals' recommended protocol. With Retinol: Use on alternate nights to avoid over-exfoliation. Start slowly and monitor skin tolerance. With other AHA/BHA: Not recommended to layer additional acids as this product already contains multiple exfoliating acids. This could lead to irritation and barrier damage.
This serum is best suited for oily, combination, and acne-prone skin types, particularly those also concerned with early signs of aging. It excels at controlling sebum, clearing pores, and smoothing fine lines. It may be too drying for very dry skin types or those with compromised skin barriers. Sensitive skin should patch test and introduce gradually.
Results can vary, but clinical studies and user reviews show: Days 1-2: Some notice immediate improvement in blemish size. Week 1-2: Reduced oiliness and smoother texture. Week 4: Significant improvement in breakouts and early anti-aging benefits (28% improvement in fine lines in studies). Week 8: Optimal results with 39% reduction in sebum and continued improvement in clarity and tone.
Apply after cleansing and toning, but before moisturizer and sunscreen. In the AM: Cleanser β Toner β Vitamin C β Blemish + Age Defense β Moisturizer β Sunscreen. In the PM: Cleanser β Toner β Blemish + Age Defense β Moisturizer. If using retinol, alternate nights with this product.
No, Blemish + Age Defense is non-comedogenic with a 0/5 comedogenic rating. The oil-free formula contains no pore-clogging ingredients. In fact, the salicylic acid and LHA actively work to unclog existing pores. It's specifically designed for acne-prone skin and will not cause breakouts when used as directed.
The product has a 12-month Period After Opening (PAO). With the recommended 4-5 drops per application used once or twice daily, a 30ml bottle typically lasts 3-6 months depending on usage frequency. Store at room temperature away from direct sunlight to maintain potency throughout its shelf life.
Verdict: SkinCeuticals Blemish + Age Defense is a premium, clinically-proven serum that delivers on its dual-action promise. The unique 5-acid formula effectively targets both adult acne and early signs of aging, making it an excellent choice for those dealing with both concerns. While the price point is steep and the alcohol content may not suit everyone, the dermatologist-backed formulation and visible results justify the investment for oily, acne-prone skin types seeking anti-aging benefits. For best results, commit to consistent use with proper sun protection.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.

EU Allergen-Free
EU Allergen-Free
Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.
For more information regarding the EU's Scientific Committee on Consumer Safety, please visit their official website.
Disclaimer
The EU Allergen Free label is for the 26 ingredients identified by the EU SCCS and products will be only flagged if a suspected ingredient is on it's ingredient list. It is possible for cosmetics to contain one of the suspect ingredients without it appearing on the ingredient list due to it not reaching the concentration threshold to disclose it and cosmetic manufacturers choice to not disclose it.
Also note, the EU Allergen Free label is not personalized for your own allergies you may have and it does not constitute as medical advice.

Fungal Acne (Molassezia) Safe
Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
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 Β«promisesΒ» 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.
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

What are Ingredients Related to Skin Type?
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.
Pro Tip Alert!
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.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!

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.
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.
