⚠️
Pregnancy

βœ…
Breastfeeding

Topical salicylic acid is unlikely to be absorbed into breastmilk. Avoid applying to areas that may contact baby's skin.

βœ…
Fungal Acne (Malassezia) Safe

Formula contains no ferments, problematic fatty acids, or esters. Salicylic acid and niacinamide are beneficial for fungal acne.

βœ…
Non-Comedogenic

Dermatologist tested and confirmed non-comedogenic. Will not clog pores or cause additional breakouts.

⚠️
Sun Sensitivity

Contains BHA which increases sun sensitivity. Always use SPF 30+ during the day when using this product.

ℹ️
Sensitive Skin

πŸ”¬ Ingredient Breakdown

πŸ§ͺ Salicylic Acid 2% Proven

A beta hydroxy acid (BHA) that penetrates oil-filled pores to dissolve sebum buildup, exfoliate dead skin cells, and reduce inflammation. The maximum OTC concentration for acne treatment.

  • FDA Approved: Recognized as an effective OTC acne treatment at 0.5-2% concentration
  • Oil-Soluble: Unlike AHAs, BHA penetrates into pores for deep cleaning action
  • Anti-Inflammatory: Related to aspirin, helps reduce redness and swelling
⚠️
May cause dryness or peeling initially. Start slowly and always use sunscreen.

✨ Niacinamide 4% Proven

Vitamin B3 derivative that regulates sebum production, minimizes pore appearance, and fades post-inflammatory hyperpigmentation while strengthening the skin barrier.

  • Sebum Control: Clinically shown to reduce oiliness and shine
  • Barrier Support: Increases ceramide production for stronger skin
  • Brightening: Inhibits melanin transfer to fade dark spots and acne marks
βœ…
Safe for all skin types including sensitive skin. Works synergistically with acids.

πŸ‹ Lactic Acid 3% Proven

A gentle alpha hydroxy acid (AHA) that exfoliates the skin surface, promotes cell turnover, and provides hydrating benefits thanks to its humectant properties.

  • Gentle Exfoliation: Larger molecule size makes it gentler than glycolic acid
  • Hydrating: Natural humectant that attracts moisture to skin
  • Texture Smoothing: Improves rough, uneven skin texture over time

🌾 Azelaic Acid Undisclosed Proven

A naturally occurring dicarboxylic acid with antibacterial, anti-inflammatory, and tyrosinase-inhibiting properties. Effective for both acne and post-acne marks.

  • Antibacterial: Kills acne-causing bacteria on the skin
  • Anti-Inflammatory: Reduces redness associated with acne and rosacea
  • Brightening: Inhibits tyrosinase to fade hyperpigmentation
βœ…
Generally considered safe during pregnancy and breastfeeding. Gentle enough for sensitive skin.

🌿 Witch Hazel Extract Proprietary Traditional

Thayers' signature ingredient, sourced from their family farm in Connecticut. Alcohol-free extraction preserves beneficial tannins for soothing, anti-inflammatory benefits.

  • Farm-to-Bottle: Certified organic, locally grown in Fairfield County, CT
  • 195% More Tannins: Non-distilled process preserves more beneficial compounds
  • pH Balancing: Helps restore skin's natural pH after cleansing

πŸ’§ Sodium Hyaluronate Undisclosed Proven

A low-molecular-weight form of hyaluronic acid that penetrates skin to provide deep hydration, counteracting the potential drying effects of exfoliating acids.

  • Deep Hydration: Can hold up to 1000x its weight in water
  • Plumping Effect: Helps skin appear more plump and youthful
  • Barrier Support: Prevents moisture loss while acids work

❓ Frequently Asked Questions

This serum contains 2% salicylic acid. The American College of Obstetricians and Gynecologists (ACOG) considers topical products with 2% or less salicylic acid generally acceptable during pregnancy, but it's best to consult your healthcare provider before use. For breastfeeding, topical salicylic acid is unlikely to be absorbed into breastmilk at significant levels, but avoid applying to areas that may come into direct contact with your baby.

Yes! This serum is fungal acne safe. It contains no ferments, problematic fatty acids (C11-C24), esters, or oils that feed malassezia yeast. The key ingredients - salicylic acid, niacinamide, lactic acid, and azelaic acid - are all beneficial for fungal acne and can help manage the condition.

This serum already contains salicylic acid (BHA) and lactic acid (AHA), so avoid layering additional acid products to prevent over-exfoliation. With retinol, use them on alternating nights or apply retinol at night and this serum in the morning. Vitamin C can be used in the morning before this serum, but watch for irritation. Always introduce new combinations gradually.

This serum is ideal for oily, combination, and acne-prone skin types. The salicylic acid and niacinamide help control excess oil while treating acne. Those with dry or sensitive skin should use caution - start with once every other day and always follow with moisturizer. Not recommended for very dry, eczema-prone, or compromised skin barriers.

Clinical testing shows improved hydration in just 15 minutes and visible acne clearing within 1 week. Post-acne marks typically begin fading around 4 weeks with continued use. Maximum benefits are usually seen after 8 weeks of consistent use. Some users may experience initial purging (temporary increase in breakouts) as the acids work to clear congestion.

Apply after cleansing and toning, but before moisturizer and sunscreen. The order is: Cleanser β†’ Toner (optional) β†’ Thayers Acne Serum β†’ Moisturizer β†’ Sunscreen (AM). Apply to clean, dry skin. Can be used 1-3 times daily, but start with once daily to assess tolerance.

No, this serum is dermatologist-tested and confirmed non-comedogenic. It has a comedogenic rating of 0/5, meaning it will not clog pores. In fact, the salicylic acid actively works to unclog existing pore congestion and prevent new blockages from forming.

The serum has a Period After Opening (PAO) of 12 months. Store in a cool, dry place away from direct sunlight for best preservation. The 1 oz (30ml) bottle typically lasts 4-8 weeks depending on usage frequency and whether you apply to full face or use as spot treatment.

β˜…β˜…β˜…β˜…β˜†
4.3 out of 5

Verdict: Thayers Double Action Acne Serum is an impressive multi-tasking treatment that combines proven acne-fighting ingredients at effective concentrations. The formula stands out for including 4% niacinamide, 3% lactic acid, and azelaic acid alongside the 2% salicylic acid - giving you more bang for your buck compared to single-ingredient alternatives. The alcohol-free, fragrance-free formulation with heritage witch hazel makes it suitable for most skin types, and it's one of the few affordable options that's also fungal acne safe. The main drawback is the small 1 oz bottle size, which may not last long with daily use. Overall, an excellent choice for those seeking a comprehensive, drugstore-accessible acne serum from a trusted American brand with 175+ years of history.

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 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.

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.

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.
