Retinol vs. Retinal Shot: differences and how to use them.

by Vienna in News

Discover the difference between retinol and retinal, what "shot" means, and how to use vitamin A without irritation — with tips on routine, alternating uses, and SPF.

Let's be honest: microneedling isn't for everyone. Redness, recovery time, "pricks"... it works, but it's not exactly relaxing. If you're looking for needle-free results, there's a trend gaining traction: so-called retinol/retinol "shots" .

Spoiler alert: these aren't injections . It's just a name for fast-absorbing formulas with a "boost" effect.

Retinol vs. Retinal: What's the difference?

Both are forms of vitamin A (retinoids) — known for supporting a more even-toned, smooth, and luminous complexion.

The main difference lies in the path they take to become active in the skin:

  • Retinol : requires 2 conversions in the skin to become active.

  • Retinal (retinaldehyde): requires only 1 conversion .

In practice: retinal tends to act faster , but it can also be more intense — therefore, its introduction should be gradual.

What does “shot” mean in skincare?

"Shot" is a term used to describe formulas that are typically:

  • concentrated

  • fast absorbing

  • designed to give a boost to a consistent routine

It has nothing to do with syringes — it's topical skincare.

Which to choose: Retinol Shot or Retinal Shot?

You choose Retinol if…

  • You are starting with vitamin A.

  • Do you have more sensitive/reactive skin?

  • You want to build tolerance calmly.

You choose Retinal if…

  • You already tolerate retinol well.

  • Do you want a more advanced step?

  • Are you looking for faster (and consistent) results?

How to use vitamin A without irritation (the simple method)

1) Start slowly
2 nights/week for 2 weeks → then 3 nights/week if everything is ok.

2) Only at night
Retinol/retinal = nighttime routine.

3) Hydration helps a lot.
If needed, use the "sandwich" method: moisturizer → retinoid → moisturizer .

4) SPF in the morning is mandatory.
If you use retinoids, wear sunscreen every day .

What to avoid in the same routine

To reduce irritation, avoid the following on the same night:

  • Retinoids (retinol/retinal) + AHAs (glycolic/lactic/mandelic)

  • Retinoids + BHA (salicylic)

How to switch (easy):

  • Night A: retinoid

  • Night B: AHA or BHA

  • Repeat (on alternate days)

How long before I see the results?

It depends on the skin and its consistency, but generally speaking:

  • texture/vibrance: a few weeks

  • Lines/stains: more time and regular use

The most important thing is to maintain a simple routine, with hydration and SPF.

Conclusion: retinol or retinal?

  • Retinol : best for beginners and building tolerance.

  • Retinal : faster/stronger, ideal when the skin is already prepared.

If you want progress without complications: start with Retinol Shot and move up to Retinal Shot when your skin feels comfortable.

VT Reedle Shot 100: The surreal at-home microneedling experience.

In the world of skincare, innovation is key to staying ahead. Reedle Shot 100 VT Cosmetics' product is a true testament to this, paving the way for a revolution in at-home microneedling in Korea. Developed to deliver professional-level results, this product promises to transform your skincare routine, offering deep nourishment and restoration like never before. What makes the Reedle Shot stand out? Reedle Shot 100 utilizes VT's exclusive microneedling technology — Cica Reedle™ — and this ampoule ensures that active ingredients such as niacinamide, hyaluronic acid, and Centella Asiatica extract penetrate deep into the skin. Its specific formula exfoliates, soothes, and hydrates, making it a powerful ally for improving skin texture and hydration. What are reeds? The blades are tiny, needle-like parts on the VT Reedle Shot 100. They are designed to gently touch the skin, similar to microneedling performed in dermatological clinics, but much less intensely. Microneedling is a procedure in which several fine needles pierce the skin to stimulate its regeneration, leaving it with a fresher, younger appearance. How do they work? Helping Skin Care Products Penetrate When using the VT Reedle Shot 100, the rods create microchannels in the surface layer of the skin. This allows the beneficial ingredients of the serum, such as vitamins and moisturizing components, to penetrate deeper into the skin than they normally would. Stimulating skin repair The tiny needle pricks stimulate the skin to begin the repair process, leading to the production of more collagen and elastin. These substances are like the building blocks of the skin, keeping it smooth, elastic, and youthful-looking. Thus, over time, your skin may become smoother and firmer. Making the most of the serum. Because the wands help the serum's ingredients penetrate deeper into the skin, the skin can get more benefits from the product. This means better hydration and healthier-looking skin overall. Gentle and safe Although "needles" may seem intimidating, the blades of the VT Reedle Shot 100 are extremely gentle. This makes the product safe for home use, ideal for those who want some of the benefits of microneedling without having to go to a professional. Who can benefit from the Reedle Shot? Recommended for those seeking to minimize pores and maximize product absorption, Reedle Shot is revolutionary. Whether preparing the skin for serums or for intensive treatment, this product caters to a wide audience, including people with sensitive and acne-prone skin. Key ingredients and their benefits Packed with skin-beneficial ingredients such as centella asiatica extract, madecassoside, propolis extract, and macadamia seed oil, Reedle Shot offers unparalleled nourishment. These ingredients work in harmony to soothe inflammation, hydrate, and plump the skin, providing a rejuvenated appearance. User experiments: Developing tolerance to obtain maximum benefits The Reedle Shot series, available in100 ,300 , and700 concentrations, is designed to meet various skin sensitivities and needs. Users report a tingling sensation with the lower concentrations, which is normal during the skin's adaptation process. It is recommended to gradually increase tolerance to obtain the best experience and results. Application tips for optimal results Incorporate Reedle Shot into your nighttime routine after cleansing. Apply an appropriate amount evenly to the face, massaging until fully absorbed. It is worth noting that Reedle Shot 100 is gentle enough for daily use, while caution is advised when using higher concentrations. Safety and adherence tests Due Due to the innovative nature of Reedle Shot's microneedling technology, a patch test is strongly recommended. This step is crucial, especially for those with sensitive skin or a compromised skin barrier, to ensure compatibility and avoid irritation. Where can I find Reedle Shot? Here, at our store!

Guia Completo de Skincare: Encontre os Produtos Perfeitos para o Seu Tipo de Pele - San Ha Co

Complete Skincare Guide: Find the Perfect Products for Your Skin Type

If you're still unsure how to start a skincare routine, the best way is to discover your skin type. But how do you identify your skin's characteristics to achieve a beautiful and healthy complexion? We've prepared this complete guide to help you with this discovery and the main daily care tips to keep your skin radiant. See below. Determine your skin type. Normal skin : generally does not have excessive shine or dryness and produces oil in the ideal amount. Dry skin : It generally has little natural oil. It has a dry, rough appearance and lacks shine. Oily skin: It features enlarged pores, with a high chance of developing blackheads and pimples. Oiliness is usually concentrated in the "T-zone" of the face (forehead, nose, and chin). Combination skin: It can cause dryness in specific areas of the face and oiliness in other areas, such as the T-zone (forehead, nose, and chin). Sensitive skin: it's not a skin type. Sensitivity can occur in any of the skin types mentioned above. This condition can occur for various reasons, including climate changes, reaction to acne treatment, skin diseases, lack of hydration, among others. It usually leaves the affected area red, burning, and itchy. Morning routine For a basic morning skincare routine, follow these steps: Cleanse your face with a gentle cleanser that doesn't completely strip away natural oils. Apply a serum, moisturizer, or oil. Apply sunscreen. The types of products you choose should be based on your skin type. Normal skin Cleansing: Choose something gentle, like micellar water, which contains molecules that remove dirt. Simply apply it to your skin; no rinsing is necessary. You can also use a foaming cleanser. Serum: Serums are available for various skin treatments. Choose one that meets your needs, whether it's anti-aging or moisturizing. Look for ingredients like antioxidants, nourishing oils, or retinol. Moisturizer: Just like with your serum, choose a moisturizer that meets your needs and contains antioxidants in its formula. Sunscreen: Apply sunscreen every day before leaving home. Use a good-textured, water-resistant sunscreen with SPF 30 or higher. You can opt for a moisturizer containing sunscreen as the final step in your skincare routine, before makeup, if applicable. Dry skin Cleansing: Choose a gentle cleanser, preferably fragrance-free, and use just enough to create a light lather. Pat dry with a towel and immediately apply moisturizer. Serum and moisturizer: The key to preventing dry skin is retaining moisture. Use a cream for dry skin. Ingredients to look for in these products include: Hyaluronic acid, glycerin, and lanolin. Sunscreen: Use a fragrance-free sunscreen with SPF 30 or higher. Oily skin Cleansing: Use a foaming cleanser that does not contain alcohol or oil. You don't need harsh cleansers that strip the skin of its natural oils. Choose products that remove dirt and oil and are gentle on the skin, thus avoiding possible irritation. Serums and moisturizers: Avoid any oil-based serums or moisturizers. Choose those labeled non-comedogenic – and fragrance-free for less irritation. Sunscreen: Sunscreen can aggravate acne-prone skin and cause breakouts, but it's essential for protecting your skin. Choosing barrier sunscreens based on zinc oxide or titanium dioxide can help. Be sure to choose a product labeled oil-free. Combination skin For combination skin, it may be necessary to treat specific dry or oily areas with different products. Otherwise, use a gentle foaming cleanser and apply moisturizer and sunscreen daily. Avoid any products that cause breakouts or dry skin. Sensitive skin Cleansing: Using an oil to cleanse sensitive skin can help. A pure oil, such as argan, coconut, or jojoba, can dissolve dirt and grime without additives that can irritate the skin. You can also use a very gentle liquid cleanser without added fragrance. Serum and moisturizer: the fewer products you use if you have sensitive skin, the easier it will be to identify what might be causing irritation. Choose a single product that has few ingredients and is fragrance-free. If your skin burns after using the product, discontinue use immediately. Sunscreen: A sunscreen with a barrier base containing zinc oxide or titanium dioxide is a great option. Avoid products with fragrances. Adverse effects Discontinue use of any skin product that results in burning, itching, redness, swelling, or pain. Night Routine For a basic nighttime skincare routine, follow these steps: Cleanse your skin, using a makeup remover product if necessary. Apply a facial toner, spreading it all over your face. Apply a night serum or moisturizer, or both if desired. Click on your skin type to see recommended products. Normal skin Toner: Choose a toner indicated for normal skin. Toners containing hydroxy acids help with ultraviolet ray damage, while those with antioxidants – such as vitamins C and E – can treat free radical damage and scarring. Serum or moisturizer: Choose a serum or moisturizer for nighttime use. A cream based on vitamin A, for example, can help with collagen production, while retinol helps combat signs of aging. Dry Skin Toner: Skip this step or use a toner that offers hydrating benefits. Avoid alcohol-based toners. Serum or moisturizer: oil-in-water formulations, such as lightweight gels, lotions, and serums, are ideal for normal to dry skin. Oily Skin Toner: Use a toner that is gentle and balanced, avoiding alcohol- or oil-based toners. Look for non-comedogenic brands. Serum or moisturizer: choose an oil-free and non-comedogenic moisturizer. Opt for products with antioxidants, such as resveratrol, quercetin, and cinnamic acid, to help reduce the appearance of inflammation. Combination Skin For nighttime skincare for combination skin, choose products that won't aggravate or irritate the skin condition. Salicylic acid is a great active ingredient for cleansing combination skin. Always apply thin layers of product. Sensitive Skin Toners: skip this step or use a very mild, natural toner. Serum or moisturizer: moisturizers containing humectants – such as glycerin and hyaluronic acid – work well for sensitive skin. Preventing moisture loss with creams containing barrier molecules, such as petroleum jelly and dimethicone, can also help.

How to Get Rid of Those Stubborn Pimples on Your Forehead

How to Get Rid of Those Stubborn Pimples on Your Forehead First of all, it's important to know how to identify closed comedones — also known as whiteheads! The first step to treating any type of acne is understanding exactly what type you're dealing with. Similar to whiteheads, fungal acne and milia can also appear on the forehead as small, raised bumps. So let's understand the differences between them! 📖 Related article: What Type of Acne Do You Have? Fungal acne is caused by a yeast infection and manifests as small, red, itchy pimples. Whiteheads (closed comedones) are white, itch-free, and filled with pus. Another possible culprit is milia , which result from a buildup of keratin below the surface of the skin. They appear as small, hard, white bumps. Unlike whiteheads, milia are pus-free and do not cause inflammation around the affected area. If you've already identified those stubborn spots on your forehead as closed comedones, take a deep breath—they're annoying, yes, but easy to treat. Here are our most effective tips for getting rid of them: Tips for Treating Closed Comedones (aka Whiteheads) 1. Double Cleanse! An essential step in the world of Korean cosmetics, double cleansing consists of two steps: First, use an oil-based cleanser to remove makeup, sunscreen, and other oily impurities; Then follow with a water-based cleanser to remove dead skin cells, bacteria, and water-soluble residue. By cleansing your face twice, you ensure that you remove all the impurities that can clog your pores and cause acne. 💧 See our complete collection of cleaning products here. 2. Tea Tree Oil Tea tree oil is one of the most popular natural acne treatments. It has anti-inflammatory and antimicrobial properties, ideal for eliminating acne-causing bacteria and soothing inflamed skin. If you're looking for an effective option, try TOUN28's T8 Tea Tree Oil , which contains 100% pure oil. If you have sensitive skin, you can dilute a drop or two in your moisturizer for a gentler version. 3. Exfoliate! Exfoliation is essential for removing dead skin cells. Fewer dead cells = less chance of pores becoming clogged with blackheads! You can opt for physical or chemical exfoliants , but we recommend chemical exfoliants—they work deep, dissolving hidden impurities. We love COSRX Two-in-One Poreless Power Liquid , which is suitable even for sensitive skin and can be used daily. Want a more powerful routine? You can combine this product with other more intense chemical exfoliants. 4. Retinol Retinol is known for its anti-aging benefits, but it's also a great ally against whiteheads. It works at the cellular level, accelerating skin renewal, reducing inflammation, and controlling oil production—all the things you need to keep your pores clear and your skin blemish-free. 5. Please. Don't. Squeeze. Like. Pimples. We know it's tempting, but squeezing or picking will only worsen inflammation, increase the risk of infection, and cause scarring. To avoid this temptation, apply COSRX Master Patch X-Large patches to the affected areas—they help protect the skin and speed healing. Conclusion Closed comedones on the forehead can be persistent, but with proper care and some patience, they're perfectly manageable. Choose the right products, maintain a consistent routine, and avoid picking at pimples—your skin will thank you!
