"It's Botox in a Bottle": 19 Serums That Make a Huge Difference

Pros: Firms the skin without the use of retinol

Cons: None

The key ingredient in this firming serum is bamboo, which contains soluble or insoluble fiber, antioxidants, proteins, vitamins, and minerals. The formula also has a natural retinol alternative complex with ingredients like chicory root oligosaccharides and tara tree. You can use this on your face and neck.

What a reviewer said: "This has worked wonders on my neck and jawline; it just lifts and firms up loose, dry skin. It seriously took a few years off in just a month's time! I'm buying some more to gift to my girlfriends!"

Pros: Clinically proven to tighten the skin

Cons: High price point

Many reviewers say that the splurge-y price tag is worth it. The lightweight serum contains plankton extract and red algae (to smooth), hyaluronic acid (to plump and hydrate), and purslane (for overall skin health).

What a reviewer says: "This is literally like Botox in a bottle! I use it on special occasions as the last step in my routine, and it makes my skin look so firm and lifted. Yes, it's expensive, but you only need the smallest amount. It does leave a tight feeling, but I think that means it's working and tightening/firming my skin!"

Pros: Visibly brightens dull skin

Cons: Potentially irritating to sensitive skin

This oil-free serum is infused with resveratrol, a powerful vine antioxidant that targets fine lines and wrinkles. Other key ingredients include hyaluronic acid to hydrate the skin and a vegan collagen alternative.

What a reviewer says: "Once again, the fresh and discreet scent is a wonder. The serum penetrates quickly. Its application is enjoyable! I saw the difference in the firming and lifting of my skin. This serum leaves a very lightweight sensation on my face. It feels great!"

Pros: Lifts and tightens the skin

Cons: Tacky consistency when layered with moisturizers

You've got a potent hyaluronic acid formula here—there's 1.5% pure HA, to be exact. It works to deeply hydrate the face and lock moisture in, leading to plumper and firmer skin.

What a reviewer says: "I have tried everything on the market, and this is the best. I have seen a huge difference in my face and neck; this will be my one and only product now. I'm 50 years old, and this product has helped with wrinkles."

Pros: Flawless, dewy finish

Cons: Small amount of product for the price point

Here's another hydrating product. Tatcha's resurfacing and plumping serum combines lactic acid to smooth fine lines and texture with hyaluronic acid to hydrate and firm the skin. It's recommended to use it morning and night.

What a reviewer says: "Amazing! I've had large pores and slight bumps in small areas around them all my life and have tried everything. After two weeks of this, my skin looks so smooth, and my pores are much smaller. I've traded in my foundation for tinted moisturizer!"

Pros: Plumping and brightening

Cons: Sticky consistency

At just $12, this might be one of the most affordable options on our list. The serum contains Matrixyl 3000, which supports natural collagen production. Plus, it has a dual peptide for more collagen-boosting benefits.

What a reviewer says: "I'm 26 with some fine lines and fairly clear skin. I used this product in the evening, and it made my skin noticeably firmer and healthier looking, and it made fine lines less noticeable. I've been using it for about a week, and I'm really happy with it."

Pros: Affordable price point

Cons: Potentially drying formula

If you want the anti-aging benefits of retinol without having to use retinol, you can try this serum. It contains bakuchiol, a natural retinol alternative that works well with sensitive skin. The firming product is also infused with hyaluronic acid for super hydration.

What a reviewer says: "This is a moisturizing product that makes your skin glow and removes blemishes over time. Your skin texture and health will improve with consistent use. [This is] great for people who are prone to acne as this product is noncomedogenic. Perfect for sensitive skin like mine."

Pros: Gentle on sensitive skin

Cons: Possible piling when layered with moisturizers

This powerful serum is specifically designed to target fine lines and wrinkles and promote firmness and elasticity. It's recommended you apply the product before your moisturizer, focusing on any areas with wrinkles.

What a reviewer says: "I absolutely love this serum! I have acne and wrinkles and have tried many brands, but it's hard to find a serum that doesn't make me break out. This serum is so silky and gives the skin a light glow. I also use it above my eyes, where I have started to notice some light wrinkles. In just a week, I started to notice a difference."

Pros: Smoothes and moisturizes the skin

Cons: None

After using this product, you're supposed to see some results in just a day. The formula includes Olay's Amino-Peptide Complex II, which will promote the regeneration of surface skin cells, so the skin will appear plump, smooth, and firm.

What a reviewer says: "Showed improvement within days. This has been the best product I have tried. It didn't get rid of 100% of the wrinkles, but I'd say there was a 50% to 75% improvement. The only downside is you have to apply it every day to maintain the benefits."

Pros: Deeply moisturizes the skin

Cons: Breakable glass packaging 

With a gel-like consistency, this serum contains a liquid matrix of hyaluronans to firm up the skin. There are also phycocolloids, which work with the hyaluronans to plump and hydrate.

What a reviewer says: "It really tightens my face (I make sure I put it on my forehead, laugh lines, crow's-feet, 11's, and sometimes down my neck if I have put a little extra). It has a tacky feeling at first, but after you apply your makeup, you don't notice [it] as much. Makes me feel wide awake and fresh."

Pros: Hydrates skin with no residue

Cons: Potentially irritating to sensitive or acne-prone skin

What a reviewer says: "Holy grail serum—I have used Kate Somerville skin products for years. I love her skin products because they are expensive but not as bad as other brands, and I see results. Even when I try other skin products, I always find my way back to KS.

Pros: Lightweight formula with quick absorption

Cons: High price point

What a reviewer says: "This may be the single best beauty product I have ever used! Here's why: Not only does it deliver on its three promises of softening lines/wrinkles, firming skin, and evening skin tone, it actually performs much better than I would've expected. In introducing this product to my beauty routine, I made no other changes to my routine or the products I use. In one month, I have definitely noticed a softening of the fine lines around my mouth, and my age spots (from years of carelessness in the hot Florida sun) are much less noticeable. Pores are much less noticeable. My skin is much more luminous."

What a reviewer says: "I love this resculpting serum. It's pretty expensive, so I only use it on my neck and décolletage area, but it feels nice and cool going on, and it is lightweight, so you can layer lotion on top of it. It's now part of my nighttime routine."

Pros: Tones and restores the neckline

Cons: High price point

This serum is specially formulated for the neck and décolletage, working to promote collagen and elastin production. The product targets wrinkles and sagging skin while also providing moisture and protection.
