Retesting Skin Type: Key to Smarter Skincare Decisions

When Should You Retake the Skin Type Test? A Dermatologist’s Guide to Adapting Your Skincare Routine

Skincare is not static. Your skin is constantly changing due to internal and external influences like age, climate, hormones, stress, and even the products you use.

That’s why it’s essential to revisit your skin type classification from time to time—especially if you’re using the Baumann Skin Typing System to guide your skincare choices.

In my dermatology practice, I frequently recommend that patients retake the Skin Type Solutions quiz as part of their long-term skincare strategy.

Your skin type might change over time—and your skincare routine should change with it.

In this blog post, I’ll explain why, when, and how often you should retake the skin type test, and how it can help you maintain healthy, glowing skin for the long haul.

Why Your Skin Type Can Change

The Baumann Skin Typing System is built around identifying four key skin barriers that affect your skin’s overall health:

Dehydration

Inflammation

Hyperpigmentation

Aging

When you first take the Baumann Skin Type Indicator quiz, the results help categorize which of these barriers are affecting your skin the most.

A personalized skincare routine is then recommended to address those specific issues. But as your skin improves—through consistent care and proper products—your skin type can shift, and so should your routine.

Here’s how your skin may improve over time with the correct regimen:

Dehydration: Often resolves within a few weeks of using hydrating products.

Inflammation: Typically improves shortly after, especially when anti-inflammatory ingredients are added.

Hyperpigmentation: May take 12–16 weeks to noticeably fade.

Aging signs: These require ongoing care and usually show progress after several months of consistent treatment.

Once your skin improves in any of these areas, sticking with the same products could lead to over-treatment or new imbalances. That’s why it’s so important to retake the quiz and refresh your skincare plan.

When Should You Retake the Skin Type Test?

Let’s take a closer look at the specific situations where retaking the quiz is not just recommended, but necessary.

1. When Your Skincare Routine Stops Working

One of the clearest signs it’s time to reassess your skin type is when the products that once worked wonders suddenly seem ineffective—or worse, irritating.

For example:

If your skin was dehydrated and now feels oily

If your dark spots have lightened but your products still include skin-lightening agents

If breakouts return after a long stretch of clear skin

In these cases, your skin type may have changed due to progress in treatment, and continuing to use products for the “old” skin type could cause new problems. This is when a retake of the quiz is essential.

2. Seasonal Changes

Where you live can influence how dramatically your skin changes from season to season.

In hot and humid climates (like Miami), skin often stays more hydrated and oily throughout the year.

In cold, dry climates, winters may leave your skin tight, flaky, or even irritated—requiring richer creams and gentler cleansers.

During summer, your skin may become oilier, requiring lighter formulations and more robust sun protection.

If you notice that your skin feels different during certain times of the year, it’s not your imagination—your skin is adapting to the weather.

That’s why we recommend retaking the quiz at least once per season if you experience extreme seasonal variations.

3. Hormonal Shifts

Hormones play a huge role in skin health. Whether it’s oil production, collagen synthesis, or pigmentation changes, hormone fluctuations can significantly alter your skin type.

Hormonal changes may come from:

Puberty

Starting or stopping birth control

Pregnancy or postpartum changes

Menopause

Hormonal therapy (e.g., testosterone or estrogen supplementation)

Medications that alter hormone levels, such as spironolactone or tamoxifen

We advise our patients to retake the skin type quiz any time there is a major hormonal shift—and then again around 3 months later, as it often takes that long for the skin to reflect internal changes.

4. Major Lifestyle Changes or Increased Stress

Stress may not show up on a lab test—but it shows up on your skin.

When stress levels rise, your body produces more cortisol. This hormone increases blood sugar, which can lead to:

More frequent breakouts

Greater skin inflammation

Accelerated aging

Events such as starting a new job or school, moving, becoming a parent, or dealing with a breakup can all increase stress levels and impact your skin.

On the flip side, reduced stress (say, after a vacation or recovery from a difficult life event) can improve skin health. In both cases, a change in stress level is a great reason to retake the quiz and adjust your routine accordingly.

What Happens After Your Skin Improves?

Let’s say you’ve followed your customized routine for 90 to 120 days, and your skin is doing great: no more flaky dryness, reduced redness, fewer breakouts, and a more even tone.

Now what?

You should retake the quiz to determine your new skin type.

Continuing to use products designed for problems you no longer have—such as hyperpigmentation or inflammation—could lead to irritation or unbalanced skin.

For example, if your dark spots are gone, there’s no need to continue using aggressive skin-lightening ingredients.

By updating your skincare routine to suit your current skin needs, you can focus on maintaining your improvements and preventing future issues.

How Often Should You Retake the Quiz?

Here’s a simple guideline:

Trigger Recommended Quiz Frequency

No major changes Once a year

Seasonal shifts Every 3–4 months

Hormonal changes Immediately after the change, and again 3 months later

Increased or decreased stress As soon as the stress level changes noticeably

Routine no longer effective Immediately

Skin problems have improved or disappeared After 90–120 days of consistent product use

Not Sure If Your Skin Type Is Correct?

Another sign that you may need to retake the test is if your current skin type description doesn’t resonate with your experience.

The most common confusion is around the “P” designation for pigmented skin types. Many people assume this refers to ethnic background or natural skin tone—but it doesn’t.

In the Baumann Skin Typing System, “P” means you have visible dark spots or uneven pigmentation that you want to lighten.

If you don’t have those, you’re classified as “N” (non-pigmented), regardless of your skin color.

If you believe you’ve been misclassified—or if your skin has changed since the last quiz—it’s a good idea to reassess and make sure your skincare routine is actually aligned with your current concerns.

The Bottom Line: Your Skin Evolves, and So Should Your Routine

Skin is dynamic—it reflects your environment, lifestyle, stress levels, hormone balance, and how well you care for it.

The Baumann Skin Type Indicator quiz is a powerful tool to help you navigate these changes and maintain optimal skin health.

So don’t think of the skin type quiz as a one-and-done assessment. It’s more like a wellness check-in for your skin.

Just like you visit the doctor for annual physicals, your skin deserves regular re-evaluation, too.

DQH Can I use salicylic acid first and then vitamin C? It’s easy to create a skincare routine, but knowing how to use it is another thing entirely. In most cases, if you’re not getting the desired skin results, it could be due to the layering of conflicting ingredients. So, is it possible that salicylic acid and vitamin C are such ingredients? Or are these active ingredients the duo that’s been missing from your skincare routine? If you want answers, stick around because today we are going to explain the benefits of salicylic acid and vitamin C and how they can be used in your daily life. What are the benefits of salicylic acid for skin? Salicylic acid is one of the most commonly used beta hydroxy acids and is favored by many people with oily, acne-prone skin. This acid is derived from willow bark, and unlike its water-soluble relatives (called alpha-hydroxy acids), salicylic acid is oil-soluble, which means it can penetrate deeper into the lower layers of the skin. Once it reaches the lower layers, it can help unclog pores of excess sebum, dirt, bacteria, debris, and impurities. This results in clearer skin tones and greater definition. Not only does salicylic acid benefit the underlying layers, but the outer surface of the skin benefits as well. When applied to the skin, salicylic acid removes the buildup of dead skin cells. This is accomplished by breaking the bonds that hold dead cells to the surface. Over time, this can cause the complexion to look dull and prone to acne, blackheads, and other blemishes. If you’d like to learn more about salicylic acid and how it can improve your skin, check out this dedicated blog post from a beauty insider. What are the benefits of vitamin C for skin? Vitamin C is considered one of the most powerful antioxidants, which means it is very effective at fighting free radicals and preventing them from causing further skin damage. Examples of free radicals include pollution, central heating, UV rays and harsh climate. They attack proteins, fats and cell membranes as soon as they come into contact with the skin, causing signs of premature aging such as fine lines and wrinkles as well as hyperpigmentation, flaky patches of skin and loss of elasticity. Many people usually prefer to use vitamin C in their morning routine as this ingredient gives the complexion a radiant glow. You’ll also find that vitamin C can target areas of hyperpigmentation, plumping the skin and reducing the appearance of fine lines and wrinkles. The thing about vitamin C is that there are a lot of outdated studies going back to the 1950s that describe vitamin C as an unstable skin component. Thanks to improvements in modern technology, this is no longer the case as all products now contain a stable form of vitamin C. Visit The Beauty Insider to learn more about vitamin C. So please check out our blog post. Can I use salicylic acid first and then vitamin C? Yes, you absolutely can. In fact, it’s thought that using salicylic acid before using vitamin C ensures it penetrates faster and works faster. This is an efficient way to utilize two power sources, and the reason has to do with pH. For example, the skin’s natural pH is about 4.7, making it slightly acidic. Salicylic acid and vitamin C are also both acidic, and you’ll find that vitamin C is absorbed quickly into the skin. Therefore, using salicylic acid beforehand can increase the acidity of the skin and allow vitamin C to penetrate into the skin faster. While this is considered an effective way to combine two powerful ingredients, you need to be aware of your skin type and how it reacts to certain active ingredients. Even people with perfect, normal skin can experience skin sensitivity and irritation. Therefore, always consult a doctor or dermatologist before using any new products on your skin. It’s also important to follow skin application rules. In this case, you need to use the product correctly to ensure you get the best results for your skin. If you’re not sure what I mean, the basic rule for skin is to start with the thinnest consistency and work your way up to the thickest consistency. This prevents a barrier from forming on the surface, preventing other active ingredients from penetrating the skin. Can I use salicylic acid at night and vitamin C in the morning? Yes, absolutely, this is considered the most effective way to get returns without any adverse side effects. This is because there is enough time between applications to ensure that the skin’s pH levels return to balance. You’ll also find that Vitamin C is rich in antioxidants and is perfect for use in the morning to ensure your skin is protected and looking its healthiest. Due to the small size of salicylic acid molecules, it is an acid that is able to reach the deepest parts of the skin. While this is effective at keeping skin clear, it also increases the risk of irritation and photosensitivity. Therefore, many people prefer to use powerful BHAs in their evening routine without exposure to UV rays, pollution, or harsh weather. Warning: If you avoid using sunscreen every day, none of these ingredients will do what your skin needs. The combination of chemical peels and powerful ingredients increases the risk of further damage to the skin’s surface. Use SPF 50 every day to keep your skin protected and your lipid barrier healthy, even on cloudy days, keeping your skin in top condition.
