Good products, shipping was okay

I ordered the CP Serum and a small bottle of LacSal Serum. The products arrived well-packaged. I've been using the CP Serum for a few weeks now and my skin feels a bit smoother, which is nice. Shipping took about a week to get to me in Arizona, which is decent but not super fast. I also wish they offered more detailed usage instructions for combining products, as I had to look up some things on their blog.

My skin feels better!

Got the Super Cop 2X and some Emu Oil. My skin was looking pretty rough, and I wanted to try something different. It took a few days to get here, but I've been putting it on for about a month. My face actually feels softer, and some of my old sun spots look a little less noticeable. I'm happy with it.

I'm thinking of trying their Hair Signals Therapy Solution for hair thinning. Has anyone seen actual results from this, or is it just hype?

R Rahul87 3 days ago ✓ Best Answer

I've been using Hair Signals for about 6 months, and I definitely see less shedding and some new baby hairs around my hairline. It's not a miracle cure, but it has made a noticeable difference for me. Consistency is key.

R Rahul87 3 days ago

About 3 months before I really noticed a change.

R Rohan 3 days ago

That's encouraging! How long did it take to see results?

A AmitM 3 days ago

Following. My hair is getting thinner too.

S Sneha 3 days ago

Curious too.

S Shruti 3 days ago

My husband tried it for a year, didn't do much for him. Maybe his thinning was too advanced. Everyone's different I guess.

K Karan_S 3 days ago

Yeah, I heard it works better for early stages.

My last Skin Biology order took almost two weeks to arrive. Is shipping always this slow now? Used to be faster.

A Anjali 4 weeks ago

Mine arrived in about 5 days last month, maybe it depends on what you ordered or where you are?

N NikhilS 4 weeks ago

Could be location dependent. I'm in the south.

C coolboy88 4 weeks ago

I ordered Super Cop 2X and it took 8 days to reach me in Bangalore. Not super fast but not terrible.

N NikhilS 4 weeks ago

Hmm, I'm in Mumbai. Maybe it's just a busy period for them.

S Swati 4 weeks ago

Sometimes during holiday sales it gets backed up. Did you order during a sale?

N NikhilS 4 weeks ago

No, just a regular order.

Just got my first order from Skin Biology, a bit confused about using GHK-Cu with my usual hydroxy acid serum. Dr. Pickart's site says be careful, anyone have a good routine for this?

R Rahul87 4 weeks ago ✓ Best Answer

Hey Priya, I use them on alternating nights. So, one night GHK-Cu (usually the CP Serum for me), next night my AHA/BHA. Never at the same time, it can deactivate the peptides.

A AmitM 4 weeks ago

Good point on the deactivation. I heard that too.

S Sneha22 4 weeks ago

Yeah, definitely separate them. I wait at least 12 hours between them.

D Deepak91 4 weeks ago

I actually use my hydroxy acid cream in the morning and GHK-Cu at night. Works perfectly for me, no issues.

P PriyaK 4 weeks ago

Interesting, I might try that. Thanks!

D deepu 4 weeks ago

I tried buffering once by waiting like 30 min, but still got a bit of redness. Stick to alternating days. My skin is pretty sensitive though.

P PoojaR 4 weeks ago

Sensitive skin here too, alternating is key.

What's the difference between CP Serum and Super Cop 2X? I want something for deeper lines and scarring.

M maxwell 6 days ago ✓ Best Answer

Super Cop 2X is much stronger. CP Serum is good for general skin health, maintenance, and lighter issues. If you're targeting deeper lines and scars, Super Cop 2X or even the GHK Luxury Copper Serum would be more effective. Start slow with Super Cop though, it's potent.

G Gaurav 6 days ago

Thanks! I'll definitely go for the stronger one then.

D deepu 6 days ago

Yeah, Super Cop is intense. I had some peeling when I first started.

P PriyaK 6 days ago

CP Serum is more for everyday use and preventative. Super Cop 2X is where you go for repair and more aggressive treatment. It has a higher concentration of copper peptides.

G Gaurav 6 days ago

Makes sense. I need the repair.

Thinking of trying Skin Signals Solution for some redness and mild sun damage. Anyone had good results with it?

P PoojaR 3 weeks ago ✓ Best Answer

I've been using Skin Signals for about 3 months for similar issues. My redness has definitely calmed down, and some of the smaller sun spots are less noticeable. It's subtle but consistent.

M Meera 3 weeks ago

Good to know, I'm looking for something gentle.

R Rahul 3 weeks ago

Following this thread, I have similar concerns.

D Deepak 3 weeks ago

Same here, very curious.

R Rohit 3 weeks ago

It worked okay for my redness, but didn't do much for my sun damage. For that, I had better luck with their P&R High-Retinol Cream.

M Meera 3 weeks ago

Thanks for the comparison, I'll keep that in mind.

My loyalty points just reset on Skin Biology's site, but I had a good amount saved up. Did anyone else experience this, or is it just me?

D Deepak91 3 days ago ✓ Best Answer

I had a similar issue once, contacted their customer service, and they were able to restore them. Might be a glitch on their end.

D Divya 3 days ago

That's good to hear. Hopefully they can help me too.

A Anjali 3 days ago

Keep us posted on what they say.

P PoojaR 3 days ago

Oh no! Mine are still there. Did you check your account history? Sometimes points expire after a certain period if you don't make a purchase, but I don't recall Skin Biology having that policy.

D Divya 3 days ago

I just checked, no mention of expiry. I sent them an email.

Does Skin Biology have a military discount? My husband is asking.

A Ankit 1 week ago

I don't think they have a direct military discount listed on their site, but sometimes they offer professional discounts for estheticians. Might be worth contacting customer service directly to ask.

S Shruti 1 week ago

Good idea, I'll tell him to check.

R Rajesh 1 week ago

I haven't seen anything about a military discount from them personally. Usually, I just look for coupon codes or wait for sales.

K Kavita 1 week ago

Same here. Never came across one.

Got an email about a holiday sale at Skin Biology. Are their holiday discounts usually worth waiting for, or is it better to just use a first-time buyer code if I'm new?

T techfreak 2 weeks ago ✓ Best Answer

Holiday sales can be good, especially around Diwali or New Year. Sometimes they offer like 20-25% off sitewide, which is better than the usual first-time buyer 10-15% discount. If you're buying a few things, definitely wait.

R RahulK 2 weeks ago

Yeah, I saw a good one last year for Republic Day too.

K Karan_S 2 weeks ago

Good point, I'm planning a bigger order.

S Sneha 2 weeks ago

I think the first-time buyer discount is pretty standard, but the holiday ones can be product-specific too. Depends what you're looking for.

P Priya 2 weeks ago

True, sometimes it's like 30% off certain serums.
