Texture & feel
SENSORYPore-Perfecting Complex
Farnesol, adipic acid, agarikon mushroom, and prickly pear dissolve waxy buildup within pore walls and flush away impurities for an instant filtered look.
7 Alpha Beta Acids
A proprietary blend of glycolic, salicylic, lactic, mandelic, malic, citric acids, and willow bark extract that exfoliates both surface and within pores.
Silicone-Free Blurring
Adipic acid creates a smoothing, pore-filling effect without silicones, so you get a filtered finish that actually treats pores instead of just masking them.
Antibacterial Protection
Farnesol and salicylic acid inhibit the growth of acne-causing bacteria while clearing existing blockages, helping to prevent future breakouts and blackheads.
Safety & compatibility
SAFEContains retinol and salicylic acid, both of which are not recommended during pregnancy or breastfeeding. Consult your OB-GYN before use.
Contains Polysorbate 80, Polysorbate 20, Caprylic/Capric Triglyceride, and Isopropyl Jojobate which can feed Malassezia yeast and worsen fungal acne.
Mostly non-comedogenic ingredients. The lightweight liquid formula is designed to clear pores rather than clog them. Suitable for acne-prone skin.
Dr. Dennis Gross Skincare is certified cruelty-free and all products are vegan. No animal testing at any stage of development.
Multiple AHAs and BHA may cause sensitivity in some users. Start every other day and build to daily use. Always wear SPF during the day as acids increase sun sensitivity.
Free from parabens, silicones, formaldehydes, phthalates, mineral oil, coal tar, and sulfates (SLS & SLES). Formulated by a board-certified dermatologist.
Low concentration of retinol provides anti-aging benefits but may cause purging in first 2-4 weeks. Avoid combining with other retinoid products.
Includes lavender extract and bergamot fruit oil. Those with sensitive skin or fragrance sensitivities should patch test before full application.
Ingredient breakdown
INGREDIENTSSalicylic Acid (BHA)Proven
The gold standard BHA for pore treatment. Oil-soluble, so it penetrates deep into pores to dissolve sebum plugs, reduce blackheads, and calm inflammation. Also has antibacterial properties.
- Mechanism: Penetrates oil-filled pores to exfoliate from within, dissolving waxy buildup and dead skin cells that cause blackheads
- Clinical Evidence: Extensively studied for acne and pore treatment; shown to reduce comedones by 40-60% in 8-12 weeks at 2% concentration
- Anti-inflammatory: Structurally related to aspirin, providing potent anti-inflammatory action that reduces redness around blemishes
Glycolic Acid (AHA)Proven
The most researched and potent AHA. Water-soluble exfoliant that works on the skin surface to lift dead cells, reveal brighter skin, and boost collagen production at higher concentrations.
- Mechanism: Breaks the bonds between dead skin cells on the surface, accelerating cell turnover and improving skin texture
- Collagen Boost: At concentrations above 10%, proven to stimulate collagen synthesis for firmer skin over time
- Brightening: Reduces hyperpigmentation by promoting exfoliation of melanin-containing cells
FarnesolProven
A naturally-derived antibacterial agent found in plants like citronella and neroli. Targets acne-causing bacteria and helps dissolve waxy buildup within pores for clearer skin.
- Antibacterial: Inhibits growth of P. acnes and other bacteria on skin surface and within pores
- Pore Clearing: Works synergistically with AHAs/BHA to flush impurities from deep within pore walls
- Fragrance Note: Also classified as a fragrance ingredient with a sweet floral scent; may be sensitizing for some
Mandelic Acid (AHA)Proven
A gentle AHA derived from bitter almonds. Larger molecular size means slower penetration and less irritation compared to glycolic acid, while still providing antibacterial and exfoliating benefits.
- Gentle Exfoliation: Larger molecular weight makes it less likely to cause stinging or irritation, ideal for sensitive-leaning skin
- Antibacterial: Has natural antibacterial properties that help reduce acne-causing bacteria
- Hyperpigmentation: Effective at improving dark spots, especially in darker skin tones where glycolic acid may be too aggressive
Retinol Low %Proven
Vitamin A derivative and the most extensively studied anti-aging ingredient. Accelerates cell turnover, boosts collagen production, and helps regulate oil production for refined pores over time.
- Cell Turnover: Speeds up skin renewal cycle, helping to keep pores clear and skin smooth
- Anti-Aging: Proven to reduce fine lines and wrinkles, improve skin firmness, and even out skin tone
- Oil Regulation: Helps normalize keratinization and reduce sebum production for less oily, less congested skin
Sodium HyaluronateProven
The salt form of hyaluronic acid with a smaller molecular weight for deeper skin penetration. Acts as a moisture magnet, attracting up to 1000x its weight in water to keep skin hydrated and plump.
- Deep Hydration: Smaller molecules penetrate further into skin than standard HA, providing hydration at multiple levels
- Barrier Support: Helps maintain skin barrier function even while using exfoliating acids
Fomes Officinalis (Agarikon Mushroom) ExtractPromising
A rare medicinal mushroom extract that helps control shine, reduce inflammation, and firm the skin to make pores appear smaller. Part of the serum's unique Pore-Perfecting Complex.
- Mattifying: Helps regulate sebum production and control excess shine throughout the day
- Skin Firming: Tightens skin around pores, making them appear visibly smaller
Phytic Acid & Pentasodium PentetatePromising
Chelating agents that dissolve the waxy sebaceous plugs deep within pore walls. They bind to mineral deposits and oils, flushing out debris that keeps pores stretched and enlarged.
- Deep Pore Cleansing: Targets and dissolves the hardened sebum plugs that cause persistent enlarged pores and blackheads
- Antioxidant: Phytic acid also acts as an antioxidant, helping to protect skin from environmental damage

Where it fits in your routine
ROUTINEFor best results, use after the Alpha Beta Daily Peel. Apply to clean, dry skin before moisturizer. Use AM and/or PM. Always follow with SPF during the day.
How to use
HOW TO USECleanse & Dry
Start with clean, dry skin. Pat face dry after cleansing. If using the Alpha Beta Daily Peel, apply the serum after completing both peel steps.
Dispense 3-4 Drops
Use the dropper to dispense 3-4 drops into your palm. A little goes a long way with this concentrated formula.
Apply & Massage
Gently massage the serum onto your face and neck using upward strokes. Can be used as an all-over treatment or as a targeted spot treatment on pore-prone areas like the nose and cheeks.
Let It Absorb
Allow 1-2 minutes for the serum to fully absorb before layering moisturizer and sunscreen. Works beautifully under makeup as a pore-blurring primer.
Who is it for?
WHOPerfect for you if:
- You have enlarged or visible pores, especially on nose and cheeks
- Blackheads and congestion are persistent concerns
- You want a silicone-free pore blurring effect under makeup
- You prefer clinically-tested, dermatologist-developed formulas
- Oily or combination skin that needs oil control without dryness
- You want both instant cosmetic results and long-term treatment benefits
Consider alternatives if:
- You are pregnant or breastfeeding (contains retinol and salicylic acid)
- You have fungal acne / Malassezia folliculitis
- Your skin is very dry and easily dehydrated by acids
- You are already using strong retinoids (tretinoin, adapalene) and multiple acids
- Budget is a priority and $65/oz is outside your range
- You are highly sensitive to botanical extracts or fragrance components
Skin type compatibility
SKIN TYPESIdeal match. Controls excess oil, shrinks pore appearance, and mattifies without stripping. The silicone-free formula treats pores rather than just masking them.
Great for T-zone oil control without drying out cheeks. Can be used as a spot treatment on oilier zones or all over. Lightweight enough for daily use.
Works well for maintaining smooth texture and preventing blackheads. The acids provide gentle exfoliation while hyaluronic acid and panthenol maintain hydration.
Multiple acids may feel drying. Start with every other day use and always follow with a rich moisturizer. Some dry skin users report the serum can feel tight.
Contains 7 active acids plus retinol and botanical extracts. Patch test recommended. In clinical trials, 100% of subjects agreed it was non-irritating, but proceed cautiously.
Salicylic acid and farnesol target acne bacteria and unclog pores effectively. Low comedogenic rating. Not suitable if you have fungal acne specifically.

- A little goes a long way; 3-4 drops covers entire face
- Works beautifully under makeup as a pore-blurring primer
- Dermatologist-developed with pharmaceutical-grade ingredients

- Reduces blackheads and prevents new ones from forming
Criticized
- Premium price ($65 for 1 oz) is a significant investment
- Can be drying for those with dry or very sensitive skin
- Some users see no improvement even after months of use
- Not pregnancy or breastfeeding safe
- Not fungal acne safe due to polysorbates and esters
- Thin, watery consistency can feel insubstantial
- Results require consistent daily use to maintain
- Contains botanical fragrance ingredients (lavender, bergamot)
Budget-friendly alternatives (dupes)
DUPESFocuses on salicylic acid (BHA) only at 2% concentration. Excellent for blackheads and pore clearing. Lacks the multi-acid AHA complex, farnesol, and pore-filling adipic acid, but is the gold standard BHA product. 4 oz bottle offers much better value per ml.
Extremely affordable BHA treatment targeting pores and blackheads. Uses squalane as a base rather than water. Simpler formula without the multi-acid blend, retinol, or pore-perfecting complex. Great entry point for those new to BHA.
Different mechanism: uses niacinamide to regulate sebum and reduce pore appearance rather than acids. Much gentler approach. No exfoliating acids or retinol. Pregnancy safe alternative. Ideal for those who want pore minimizing without chemical exfoliation.

Frequently asked questions
FAQNo. This serum contains both retinol and salicylic acid, which are not recommended during pregnancy or breastfeeding. Retinol is a vitamin A derivative that has been linked to birth defects at high doses, and salicylic acid is generally advised against during pregnancy by most dermatologists. If you are pregnant, planning to become pregnant, or breastfeeding, consult your OB-GYN before use. Consider pregnancy-safe alternatives like niacinamide-based pore treatments instead.
No. This serum is not considered fungal acne safe. It contains several ingredients that can feed Malassezia yeast, including Polysorbate 80, Polysorbate 20, Caprylic/Capric Triglyceride, and Isopropyl Jojobate. If you have confirmed fungal acne (Malassezia folliculitis), this product may worsen your condition. Look for FA-safe alternatives that avoid polysorbates, fatty acids, and esters.
This serum already contains retinol and multiple AHA/BHA acids, so layering additional retinoids or strong acids on top can increase the risk of irritation and over-exfoliation. According to Dr. Dennis Gross, the serum works well with the Alpha Beta Daily Peel (use the peel first, then the serum). Vitamin C can be used at a different time of day (e.g., vitamin C in the morning, this serum at night). If you are new to acids, start with this serum alone and gradually introduce other actives once your skin adjusts.
This serum is best suited for oily, combination, and normal skin types. It excels at controlling oil production, shrinking pore appearance, and clearing blackheads. Those with dry or very sensitive skin may find the multiple acids too drying and should start with every-other-day application. In clinical trials, 100% of subjects agreed the serum was non-irritating, but individual experiences may vary.
In clinical trials, 81% of subjects showed significant improvement in pore appearance after just 3 days. By 1 week, 86% agreed their skin texture looked clearer and smoother. Most users report noticeable improvements within the first 1-2 weeks of consistent use. Full results for blackhead reduction and oil control typically develop over 4-8 weeks. Consistency is key; results diminish if you stop using the product.
Apply after cleansing and toning on clean, dry skin. If you use the Alpha Beta Daily Peel, apply this serum after completing both peel steps. Follow with your moisturizer and sunscreen (AM). This serum can be used both morning and evening. It also works well under makeup as a pore-blurring primer step.
This serum has a low comedogenic rating of 1 out of 5. It is specifically designed to clear and unclog pores, not clog them. The formula is silicone-free and contains multiple pore-clearing ingredients like salicylic acid, phytic acid, and farnesol. However, as with any product, individual reactions can vary, and some users with very reactive skin have reported initial breakouts as part of a purging phase during the first 2-4 weeks.
The serum has a Period After Opening (PAO) of 12 months. However, because it contains retinol, it is best used within 6-9 months of opening for maximum potency. Store in a cool, dry place away from direct sunlight. Many users report that using 3-4 drops per application, one bottle lasts several months even with daily use.
Verdict: The Dr. Dennis Gross Alpha Beta Pore Perfecting & Refining Serum is a powerful, clinically-backed treatment for anyone struggling with enlarged pores, blackheads, and oily skin. Its unique combination of 7 AHA/BHA acids, farnesol, and a silicone-free pore-filling complex delivers both instant cosmetic blurring and long-term pore treatment. The clinical data is impressive, with 81% of subjects seeing pore improvement in just 3 days. However, the premium price tag ($65/oz), the presence of retinol and salicylic acid (making it unsafe during pregnancy), and the fact that it's not fungal acne safe limit its audience. If enlarged pores and congestion are your primary concerns and you have oily to combination skin, this is one of the most effective targeted pore serums available. Budget-conscious shoppers may find similar (though less comprehensive) results with Paula's Choice BHA or The Ordinary Niacinamide.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.

Quick Product Notes
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.
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
Notable Effects & Ingredients
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.

Ingredients Related to Skin Types
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.
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.
