Key takeaways
The A Method by Tina Alster, MD, launched in 2018 after decades of dermatology and laser surgery experience.
The dermatologist-founded brand was co-created with skincare formulator Angelia Inscoe.
Its philosophy is simple: fewer purposeful products, layered in the right order, with appropriate care around professional procedures.
The Post-Care Kit reflects the original cleanse, soothe, and protect approach.
C Antioxidant Gel 20% is Dr. Alster's featured pick for antioxidant support and brighter-looking skin.
The A Method by Tina Alster, MD, grew from a problem she saw in dermatology practice: patients needed simpler guidance for caring for their skin between appointments. After decades of dermatologic laser surgery, Dr. Tina Alster introduced the line as her “practice playbook” at the 38th Annual Meeting of the American Society for Laser Medicine and Surgery in 2018.
This guide is for anyone who knows the brand but wants to understand its founder, core products, and layering approach. You can shop The A Method while exploring its everyday skin care philosophy.
How did dermatologic laser surgery at the Washington Institute shape The A Method?
Dr. Alster built The A Method around decades of clinical experience and the importance of consistent home care. She is the founding director of the Washington Institute of Dermatologic Laser Surgery, established in 1990, and a clinical professor of dermatology at Georgetown University Medical Center. She earned her B.S. and M.D. degrees from Duke University before completing her dermatology residency at Yale University. She has published hundreds of articles and eight medical textbooks.
Before launching her line, Dr. Alster spent nearly a decade consulting for Lancôme and La Mer. In 2018, she co-founded the woman-owned, physician-led brand with skincare formulator Angelia Inscoe. The initial Post-Care System paired cleansing, soothing moisture, and sun protection for patients after in-office care. She called the launch her “practice playbook” in a 2018 interview with The Georgetown Dish. Learn more about Dr. Tina Alster on Our Story.
What makes The A Method skin care approach different?
The method rests on three habits: choose purposeful products, apply them in a sensible order, and adjust the routine when skin needs extra care. These principles give each product a clear role, including between professional appointments. The A Method describes its formulas as dermatologist-tested, but that doesn't mean every product is appropriate for every skin type or skincare routine.
Start with fewer, purposeful products
A simpler routine makes it easier to understand what your skin needs and how it responds. A gentle cleanser, moisturizer, and daytime sunscreen create a practical foundation. Add a serum only when it serves a clear cosmetic goal, such as improving the look of dullness, rough texture, or fine lines. Choosing fewer products can also reduce unnecessary exposure to potential irritants and make your routine easier to maintain.
Layer from thinnest to thickest
The A Method's central layering rule is to apply lighter products before richer formulas, then finish daytime skin care with sunscreen. This lets lightweight serums contact the skin before heavier creams. Follow the product's directions and the brand's skincare layering guide, rather than assuming that stacking more active ingredients makes a routine more effective.
On her practice website, Dr. Alster describes a simple daily approach: a waterless vitamin C serum in the morning and all-trans retinol at night. It connects her professional advice to the products she developed, although the right routine still depends on your skin's tolerance and your dermatologist's guidance.
Keep post-procedure routines uncomplicated
After an in-office procedure, your dermatologist's instructions take priority over your usual product lineup. Dr. Alster's experience with microneedling, nonablative lasers, and chemical peels informed the brand's original focus on post-care. These procedures can leave skin temporarily sensitive.
Fragrance-free formulas and simple layering are part of the brand's philosophy, but that doesn't make every product suitable for freshly sensitized skin. Avoid restarting strong active ingredients until your clinician confirms the timing. The products support comfort and appearance, not the medical outcome of a procedure.
Which Tina Alster products show how the method works?
The Post-Care Kit and C Antioxidant Gel 20% explain two sides of the line: simple post-procedure care and everyday antioxidant skin care. They serve different situations, and Dr. Alster's Washington, DC practice also stocks The A Method products for in-office purchase.
The Post-Care Kit: cleanse, soothe, protect
The Post-Care Kit follows the original three-step idea with cleansing, moisturizing comfort, and mineral sun protection.The kit includes Cleanse Gentle Daily Wash, Soothe HC Recovery Balm, and Clear SPF 40 Protection Powder. Use each only as directed by your dermatologist, particularly after microneedling, a chemical peel, or a laser appointment.
A cleanser removes everyday buildup without unnecessary scrubbing, while a suitable balm can help skin feel more comfortable. Sun protection is also important, although a powder sunscreen may not be appropriate on freshly sensitized skin or sufficient as the only sunscreen layer. Check out the post-procedure skincare line for similar products and confirm timing with your clinician.
Dermatologist pick: C Antioxidant Gel 20%
C Antioxidant Gel 20% is featured as Dr. Alster's pick and is formulated with 20% THD-ascorbate, a lipid-soluble form of vitamin C. The water-free, lightweight gel offers antioxidant support against environmental free radicals while helping skin look brighter, smoother, and more even over time. It also has a silky finish that layers comfortably under moisturizer and sunscreen.
This is an everyday antioxidant step, not an automatic addition immediately after professional procedures. The product page allows morning and evening use, while the brand's practical routine places vitamin C particularly well in the morning.
How should you layer The A Method products morning and night?
A useful daily skin care routine begins with cleansing, adds one suitable serum, and ends with moisturizer, plus sunscreen in the morning. The table offers a starting point for skin that isn't recovering from an in-office procedure. The line also includes TCA Retexturizing Cream, which combines all-trans retinol and trichloroacetic acid (TCA) to support smoother-looking skin texture. This is a separate nighttime active, not an automatic addition to post-procedure care.

Retinol formulas, including Reti-Gel listed by Dr. Alster's Washington, DC practice, require care because tolerance varies. Avoid stacking retinol, acids, and multiple serums in one routine. Give your skin time to adjust.
The A Method by Tina Alster, MD: FAQs
Which two serums cannot be used together?
There isn't one universal pair of serums everyone must avoid, but layering several strong actives at once can increase irritation. Many people prefer vitamin C in the morning and retinol at night. Niacinamide and vitamin C can often work in the same routine; our article on using niacinamide with vitamin C explains how to introduce them comfortably.
What is the 4-2-4 rule in skincare?
The 4-2-4 rule is a cleansing trend involving four minutes of oil cleansing, two minutes with a second cleanser, and four minutes of rinsing. The A Method does not require this timed cleansing routine. The American Academy of Dermatology recommends washing gently instead of scrubbing, which is more important than a fixed timer.
Is The A Method the number one dermatologist skincare brand?
There is no universal ranking of which skincare brand is the best for everyone. The A Method is dermatologist-founded, drawing on Dr. Alster's practice and Angelia Inscoe's formulation experience. That background explains how the brand was developed; it doesn't guarantee that every formula suits every skin type.
How does Dr. Tina Alster's microneedling experience relate to The A Method?
Her experience with microneedling and other in-office procedures helped shape the brand’s focus on simple post-care routines. Professional microneedling, or collagen induction therapy, creates controlled micro-injuries. Skincare choices afterward depend on your dermatologist's instructions. The Post-Care Kit supports skin comfort and appearance when appropriate.
Where should I start with The A Method?
Start with a cleanser, moisturizer, and daytime sunscreen, then add one product that fits your main cosmetic goal. For everyday antioxidant care, consider C Antioxidant Gel 20%. For the days around a procedure, ask your clinician whether the Post-Care Kit is appropriate. Ready to shop? Explore those two products through the links above and choose what fits your routine.
