An essence is a lightweight, hydrating liquid used after cleansing and before serums or moisturizers. Originally popularized in Korean skincare, essences are designed to deliver a concentrated dose of hydration and active ingredients that help prep the skin for better absorption of everything that follows.

Think of it as the bridge between cleansing and treatment:

• It restores moisture lost during cleansing.
  
• It helps rebalance the skin’s pH.
  
• It improves the penetration and performance of serums and creams.
  

Think of it as a sip of hydration before your serums and creams — but one that’s infused with powerhouse ingredients. Think of your skin as a sponge — if it’s dry and depleted, it can’t absorb all the goodness from your routine. And it does more than just hydrate. That’s where essence comes in. Packed with powerhouse actives, it preps, heals, and transforms your skin from the very first step.

We don’t label Regelica as a “clean beauty” brand because the term is vague, unregulated, and often used to create fear around ingredients that are actually safe and effective. Instead, we focus on transparency—clearly sharing what’s in our formulas and why.
Our products are free of phthalates, formaldehydes, parabens, mineral oil, SLS, and synthetic dyes—not because it’s trendy, but because we prioritize skin-friendly, science-backed ingredients.
“Clean” means different things to different people. We prefer to be clear. No gimmicks, just skincare that works.
And yes—we are proudly certified cruelty-free by both Leaping Bunny and PETA. We never test on animals, and we never will.

We recommend using our Immunity Support Essence both morning and evening — right after cleansing and before applying serums or moisturizer.
For best results, apply the essence as soon as possible after cleansing — while your skin is still slightly damp.Why?
Cleansing can temporarily disrupt your skin’s pH. Our essence helps restore balance while delivering an initial layer of hydration. Applying serums and creams on damp skin helps them absorb more effectively, boosting their impact.

Yes, our essence does contain fragrance — a light, fresh citrusy scent designed to enhance your skincare experience.
It’s true that many fragrances can be sensitizing, but we’ve taken extra care to minimize that risk:

Our fragrance is a low-allergen synthetic blend, not derived from essential oils or natural sources (which are common triggers).

It’s tested non-allergenic according to EU standards.

It contains no phthalates, which are often linked to irritation.

We carefully select every ingredient to ensure safety and efficacy, but as with any skincare product, we recommend performing a patch test before applying to larger areas — especially if you have sensitive skin.

The iconic Korean “glass skin” look—clear, smooth, and intensely hydrated—is traditionally achieved by layering up to 7 layers of toner. But we’ve simplified the process. Our Immunity Support Essence is packed with multi-weight humectants that hydrate on multiple levels, helping you achieve that healthy glow and visible before-and-after glass skin effect with just one step. ✨
Consistency is key—but we made it easier (and faster) to get there.

Regelica’s Immunity Support Essence is designed to hydrate, restore your skin’s pH balance, and support its natural immunity—especially if you're looking to upgrade your skincare routine for dull skin and achieve a clear glass skin look.
It features gentle forms of Vitamin C for pH balance—an essential step after cleansing, as a balanced pH is key to supporting the microbiome of the skin and keeping its natural defenses strong.
Infused with nutrient-rich Sea Buckthorn and a skin-native microbiome complex, our essence nourishes, heals, and reinforces your skin’s resilience, promoting a radiant, thriving complexion.
If you're searching for skin care products for healthy skin or want to simplify your routine, this is your one-step solution for for pH balance, deep hydration, and visible glow.

The Immunity Essence gives a healthy, hydrated glow—plump and radiant, but never oily. It absorbs quickly, leaving skin refreshed and balanced.

Yes. The Immunity Essence is formulated with stable, gentle forms of Vitamin C, which means it can be safely combined with other ingredients such as tretinoin, ascorbic acid, peptides, and niacinamide. Since every skin type is unique, we recommend monitoring your skin’s response and adjusting use if needed.

Vitamin C is a powerhouse for brightening skin and boosting collagen, but the most well-known form—ascorbic acid—can often be irritating, especially for sensitive or reactive skin types.

That’s why in our Immunity Essence we chose gentler derivatives: Magnesium Ascorbyl Phosphate (MAP) and Sodium Ascorbyl Phosphate (SAP). These forms are more stable and less acidic, making them far better tolerated by sensitive skin while still delivering the key benefits of Vitamin C—like brightening, antioxidant protection, and collagen support.

If you have sensitive skin but still want the Vitamin C glow, MAP and SAP let you get the benefits—without the burn.

Both MAP and SAP are gentler, more stable forms of Vitamin C—perfect for people with sensitive or reactive skin.
Magnesium Ascorbyl Phosphate (MAP) is known for its hydrating and brightening properties. Unlike pure ascorbic acid, MAP is water-soluble and less acidic, meaning it’s far less likely to cause irritation. It helps fade dark spots, even out skin tone, and support collagen production—leaving skin firmer and more radiant over time.
Sodium Ascorbyl Phosphate (SAP) is another well-tolerated Vitamin C derivative with an extra benefit: it’s one of the few forms of Vitamin C shown to help acne-prone skin. In addition to brightening and collagen support, SAP has antimicrobial properties that can help reduce the bacteria associated with breakouts—making it ideal for those dealing with both dullness and blemishes.
Both MAP and SAP deliver the antioxidant protection of Vitamin C—shielding skin from environmental stress like pollution and UV exposure—while being much gentler than traditional ascorbic acid. They may work a bit slower, but their low irritation risk makes them ideal for consistent, long-term use.

Sea Buckthorn is a tiny orange berry with an impressive skincare résumé. It’s one of the few natural ingredients that contains all four types of omega fatty acids—3, 6, 9, and the rare omega-7. These healthy fats help reinforce the skin barrier, lock in moisture, and keep your skin feeling plump, smooth, and resilient.
It’s also incredibly rich in antioxidants, including vitamins C and E. In fact, Sea Buckthorn contains more vitamin C than oranges, making it a powerful ally against free radicals, pollution, and UV damage—all major contributors to dullness and premature aging. This antioxidant boost helps brighten the skin, even tone, and support collagen production for firmer, more youthful-looking skin.
On top of that, Sea Buckthorn has natural anti-inflammatory and healing properties. Traditionally used to treat burns and wounds, it’s known to calm irritation, reduce redness, and promote faster skin recovery. Whether your skin is feeling stressed, dry, or just in need of a glow-up, Sea Buckthorn is like a multitasking skin superhero—hydrating, protecting, and healing all at once.

Your skin is constantly exposed to stress—sunlight, pollution, even everyday cleansing—all of which can cause micro-damage to your skin cells, including your DNA. We all know the importance of protecting against this kind of damage to prevent premature aging. But what about the damage that’s already happened?
That’s where your microbiome comes in. Recent research suggests that certain beneficial bacteria—like Streptococcus thermophilus—can naturally stimulate your skin’s own production of DNA repair enzymes. In skincare, a fermented form of this bacteria, called Streptococcus thermophilus lysate, is used to help support the skin barrier, boost hydration, and activate those repair pathways.
It’s one of the star ingredients in our Microbiome Complex, featured in Regelica’s Immunity Support Essence.
